HRSG OPERATION AND MAINTENANCE
SECTION 1: ENGINEERING FUNDAMENTALS 1.
LEARNING OBJECTIVES
•
Explain the fundamental physical principals of: water to steam conversion, heat transfer and natural circulation for a heat recovery steam generator.
•
Explain basic functional concepts of the Heat Recovery Steam Generator (HRSG) boiler design
2.
WATER TO STEAM
The function of the boiler is to produce a specific amount of steam at a constant pressure and temperature from a specific amount of feedwater. This steam is used to drive the turbine. Water can exist in three physical states, solid, liquid or gas (vapor), depending on the corresponding pressure and temperature. Steam generation is only concerned with the liquid and vapor forms of water. Steam results from adding sufficient heat to water to cause it to vaporize or turn into a gas. This occurs in two steps: a. b.
The addition of heat sufficient enough to raise the temperature of water to the boiling temperature. A continuing addition of heat to change to change the physical state of water from a liquid to a gas (steam)
Thermal capacity (specific heat) is the quantity of heat required to produce a unit change in temperature. Water has a high thermal capacity. This means that a great amount of heat is required to cause a temperature change in water. Water cools slowly in the process of giving up absorbed heat. Specific heat is the term used in power generation for thermal capacity. Specific heat is the amount of British Thermal Units, BTU, required to raise the temperature of one pound of water one degree Fahrenheit (oF). It takes one BTU to raise the temperature of one pound of water one degree F. Other substances may require either more or less heat to raise one pound by one degree F. Enthalpy is the measure of the total stored internal energy of a substance, such as water or steam. Steam tables list the enthalpy in Btu/lb of saturated liquid (hf), and saturated and superheated steam at various pressures and temperatures. The Btu/lb Represents the amount of heat transferred to the water/steam from the combustion of fuels. Enthalpy changes are a function of temperature and pressure. The steam tables show the trends in BTU when going from a lower pressure to a high steam pressure.

STEAM GENERATION PROCESS
Latent Heat of Fusion Latent heat of fusion is defined as the amount of heat required to melt one pound of ice at 32oF to one pound of water at 32oF. This latent heat or “hidden heat” produces a change in state of the water instead of a change in temperature. 144 Btu are needed to convert one pound of ice into one pound of water at 32oF at 14.7 psig or 29.92 “Hg, the normal atmospheric pressure or absolute pressure. This process is depicted in Figure 1.
Figure 1: Latent Heat of Fusion Latent Heat of Vaporization Latent heat of vaporization is defined as the amount of heat required to change one pound of liquid water to one pound of steam (vapor). When additional heat is added to the water at its boiling point, the temperature of the water remains constant, but the physical state is changed. One pound of water at 212o F. which is the boiling point of water at 14.7 psig, requires 970 Btu to change into one pound of steam at 212o F. This process is depicted in Figure 2.

HRSG OPERATION AND MAINTENANCE Latent Heat of Condensation Latent heat of condensation, also shown in Figure 2, refers to the condition where a pound of steam at 212o F is cooled (heat is removed) to form a pound of liquid water at 212o F. The energy lost in going from a pound of steam to water is 970 Btu/lb. Sensible Heat Refer to Figure 3. When the flow of heat is not reflected in a temperature change (latent heat), it is absorbed in the fluid or substance and increases the kinetic energy of the molecules of the substance. This is called sensible heat. Water at 32o F will absorb 180 Btu of sensible heat per pound when raising the water temperature to 212o F.

HRSG OPERATION AND MAINTENANCE Heat Flow Heat is the flow of thermal energy. When heat is added or removed, temperature differentials are formed so that thermal energy can flow from one substance or area to another. Sensible heat and latent heat are merely two effects produced by heat, not different kinds of heat. When the flow of heat is not reflected in a temperature change (latent heat), it is absorbed in the fluid or substance and increases the kinetic energy of the molecules of the substance. 4.
STEAM CHARACTERISTICS
Quality of Steam The proportion, by weight, or “dry” vapor in a steam and water mixture is termed the quality of steam. Steam quality is expressed in percentages. If as quantity of steam contains 90% steam and 10% water vapor, the mixture has a quality of 90%. Saturated Steam Saturated steam is steam saturated with all the heat it can hold at the boiling temperature of water. Dry saturated steam vapor essentially contains very little moisture (dependent upon its quality), and is at saturated temperature for the given pressure. Its total heat content, or enthalpy, is equal to the heat of the liquids plus the heat of vaporization. Pressure and Temperature Relationship When water is heater to the boiling point in a closed vessel, the vapor released caused the pressure to increase in the vessel. With the increase in pressure, the boiling temperature of the water also increases. The temperature at which water boils at a given pressure is termed the saturation temperature. For each saturation temperature, there is a corresponding pressure called the saturation pressure. Figure 4 depicts the relationship between saturation temperature and saturation pressure.

HRSG OPERATION AND MAINTENANCE
Figure 4. Pressure/Temperature Relation ship The Critical Point At 3208.2 psia with a corresponding saturation temperature of 705.5o F, water and steam properties are identical. In fact the terms “water” or “steam” no longer apply since the properties of the water and liquid are the same. Instead the term “working fluid” is used when temperature and pressure are above this critical point. Boilers designed to operate at pressures and temperatures below the critical point are called sub-critical boilers. Boilers designed to operate at pressures and temperatures above the critical point are called supercritical boilers. Superheated Steam Steam heated above its corresponding saturation temperature at a particular pressure is called superheated steam. Superheated steam contains no moisture, and will not condense until its temperature has been lowered to that of saturated steam at the same pressure. Superheating of steam takes place in the various superheater sections of the boiler. Steam must be superheated before it can be sent to the turbine or process steam headers to do useful work.

HRSG OPERATION AND MAINTENANCE Degree of superheat refers to the temperature difference in degree Fahrenheit between the steam at the superheater outlet, and its corresponding saturation temperature (steam drum outlet) at a given pressure. For example, consider a superheater outlet steam pressure of 72.5 psi and a superheater outlet temperature of 572o F. The corresponding saturation temperature at that pressure is 318o F. Therefore, the degree of superheat is 5720 F minus 318o F, equaling 254o F. It must also be recognized that there is a loss in steam pressure between the drum steam pressure and the superheater outlet pressure. Superheated steam has three advantages over steam that is not superheated: •
It increases the efficiency of the turbine.
•
It prevents damage to turbine blades from condensation.
•
It is able to travel through long pipelines with little or no condensing.
Departure from Nucleate Boiling There are two types of boiling that can occur in steam generators. Nucleate boiling – is the normal boiling process in a boiler in which water is raised to the boiling point, and individual steam bubbles form as water comes in contact with the hot tube surfaces. As these bubbles form and leave the heated surface, the cool water that remains (due to proper circulation) wets the tube surfaces, thus keeping the waterwall tube metal temperatures well within allowable limits. Film boiling – is an abnormal boiling condition and is present at times when insufficient water flow or circulation exists. When this type of boiling process takes place, steam bubbles form as water comes in contact with the hot tubes surfaces. They then collect and burst forming a film of steam which blankets the hot tube surface. Waterwall tube metal temperatures increase and tube damage can result. A term commonly used to describe this condition in DNB, or Departure from Nucleate Boiling. DNB can occur during periods of excessive firing rates if the circulation ratio or tube flow is not sufficient to carry away excess heat. Steam pockets form over large areas of the inner tube diameter, creating an insulating film barrier to normal heat transfer. The transition from Nucleate Boiling to DNB is shown in Figure 5.

HEAT TRANSFER PRINCIPLES
The process of transferring thermal energy can only occur if it originates from an area or material on one temperature to and area or material of a lower temperature. Heat transfer is vital to the operation of the power plant cycle and occurs in many locations throughout the plant. 6.
HEAT TRANSFER MODES
Conduction When heat passes through a solid object, quickly moving molecules in the hot portion collide with and give up some energy to slower molecules in the cooler portion. This type of heat transfer is called conduction.

Revision: 0 04/02/05
1-7
HRSG OPERATION AND MAINTENANCE Radiation Heat transfer occurs via radiation when electromagnetic waves from a heat producing source strike a surface, and give up energy to the molecules in that surface. Burning fuels give radiant energy. Convection When a heated fluid or vapor moves to a cooler region by circulation resulting from density differences between the hot and cold areas within the fluid or vapor, this is called convection. 7.
MAIN FACTORS AFFECTING HEAT TRANSFER
Differential Temperatures (∆T) The temperature difference between a high temperature source and a low temperature source is called differential temperature. A higher ∆T will result in a greater amount of heat transfer. Thermal Conductivity Thermal conductivity is an indication of how well a material absorbs and transfers heat. A higher value of thermal conductivity means a material is capable of transmitting heat at a faster rate than a material with a low thermal conductivity. Surface Area Surface area is the area of a low temperature source that is placed in contact with a source of higher temperature. A larger exposed area will result in a higher heat Transfer Coefficient. The heat transfer coefficient is a constant factor, which mainly depends on the physical properties of the heat transferring mediums such as gasses, solids and metal tubes, and the gas velocity in the boiler. Materials are selected and arranged in the boiler according to their various heat transfer properties. Pinch Point The difference between the gas temperature leaving an evaporating section and the temperature at which boiling is occurring (saturated water temperature) is called a pinch point. The pinch point strongly influences the amount of heat transfer surface in the evaporating section. Current HRSG designs uses pinch points in the 15o to 25o F range. See Figure 16 for a graphic representation.

HRSG OPERATION AND MAINTENANCE Approach Temperature The approach temperature is the difference between the saturated-water temperature in an evaporating section and the incoming feedwater temperature. The approach temperature influences the amount of surface required for an economizer section, with exponentially increasing amounts required for very low approach temperatures. Current HRSG economizers have approach temperatures in the 15o to 25o F range. Many other operating conditions can occur at off-design points, including start-up. Some conditions will result in steaming at the exit of the economizer, such that it acts as an evaporative surface. See Figure 16 for a graphic representation. Materials Metals have good thermal conductivity. The number and arrangement of the tube assemblies placed in a boiler are selected to provide the proper tube surface area which is expressed to the hot solids/gasses so that the correct amount of heat is transferred to the water/steam to obtain design steam pressure and temperatures with design combustion temperatures. Fiberglass, silica block, and certain refractory compounds are used where heat transfer is not desired. These materials, called insulators, have low thermal conductivity and help to reduce the heat transfer. Improper insulation in the form of ash and /or dust and internal tube deposits can be very detrimental to boiler heat transfer, as indicated in Figures 6, 7, 8 and 9. Ash/dust deposits on the external surfaces of boiler tubes have lower thermal conductivity than the tube metal. A higher differential temperature is required to pass the proper amount of heat through the ash/dust to the water/steam inside the tubes. The reduction in heat flow from the tube to the boiler water/steam increases the average tube metal temperature, which can lead to tube failures from overheating. Temperature limitations for typical tube materials are shown in Table 1.

BOILER WATER CIRCULATION
Boiler circulation is defined s the movement of water, a mixture of steam and water, or steam through boiler tube circuits. There are two types of circulation: •
Natural or “thermal” circulation
•
Forced or “controlled” circulation

HRSG OPERATION AND MAINTENANCE Natural Circulation In natural circulation boilers, circulation is accomplished without the use of circulating pump. The density difference between steam and water (thermal head) is the driving force in a natural circulation boiler (Figures 10 and 11).
Figure 10: Natural (Thermal) Circulation
Cold side: The density of saturated water in the downtakes (also called downcomers) will range between 60 lb/ft3 and 30 lb/ft3, depending on the corresponding pressure and temperature in the boiler steam drum. Hot side: The steam/water mixture density in the waterwalls will be approximately 25 lb/ft3. Variations in boiler pressure have a lesser effect on the mixture density.

HRSG OPERATION AND MAINTENANCE
Figure 11: Circulation Schematic for Natural (Thermal) Circulation As boiler pressure increases, the difference between the densities of water and steam, which is the motive force for natural circulation boilers, becomes smaller (Figure 12). Thermal head differential is the resulting differential ranges between approximately 25 psi and 10 psi, with the greater differential being possible in lower pressure boilers (Figures 12 and 13).

In addition to the fact that there is less motive force in a higher-pressure boiler, there are also other factors in a natural circulation boiler, which oppose circulation. These are: •
Friction between water and tube metal
•
Friction between water and scale deposits in tubes
•
Friction in tube bends
•
Friction in lower drum and headers
•
Friction around upper drum internals
•
Friction in the steam and water separating equipment

HRSG OPERATION AND MAINTENANCE
Figure 13: Typical Boiler Static Head – Constant Circulation Ratio of 4.0 Circulation Ratio Circulation ratio is defined as the weight of water entering the downcomer, divided by the weight of steam in the water/steam mixture leaving the water wall tube circuits. Because circulation is dependent on the thermal head, which is dependent on boiler pressure, the flow of water into the downcomer increases as load decreases. At low loads of 50% of Maximum Continuous Rating (MCR) or less, the circulation ratio will be much higher since there is less steam being generated. Natural Circulation boilers are generally designed for a circulation ratio of “5” equaling a circulation ratio of 5 to 1. For example, for every 25-lb. Of water entering the downcomer, there could be as much as 5 lb of steam leaving. 9.
HEAT RECOVERY STEAM GENERATOR
The following material was copied from pages 8-30 to 8-35 of the Combustion Fossil Power text. A Heat Recovery Steam Generator (HRSG) is used to recover heat that otherwise would be lost in the exhaust from a gas turbine. This heat is then used to generate steam that will drive a steam turbine or be used in a process. Typically, the addition of an HRSG and a steam turbine boosts total output of electricity by 30 percent or more over the traditional gas turbine operating in a single cycle mode. Efficiency increases with the increased output. Gas turbines have been widely used to provide standby or peaking power for electric utilities, or for unattended service in remote locations. As described in Chapter 1, the thermal efficiency is low because of high exit-gas temperatures (800 to 1000o F, or 425 to 540oC) and high excessair levels (220 to 300 percent) in the combustion products.

HRSG OPERATION AND MAINTENANCE exhaust gas can be recovered in a heat-recovery boiler to produce additional electricity using a steam-turbine generator. The combined output of electricity from the gas turbine and the steam turbine is 30 to 50 percent greater than that obtained from the gas turbine alone, with no additional fuel input. Combined-cycle power plants for industrial power-generation application have much higher thermal efficiencies than conventional steam power plants with the same steam conditions. In general, the high thermal efficiency of a combined-cycle plant can be economically exploited if liquid or gaseous fuels are readily available and the unit can be operated continuously or operated on an interruptible basis at least 50 percent of the time at full power. Chapter 1 of the Combustion Fossil Power text identified the four major classifications of combined cycles and their associated heat rates. The two most commonly used cycles for industry employ unfired or supplementary fired heat-recovery steam generators (HRSG’s). Supplementary fired heat-recovery steam generators use firing equipment located in the exhaust gas stream in the boiler inlet transition duct. Since gas-turbine exhaust contains 75 to 80 percent of the oxygen normally found in atmospheric air, fuel may be burned without the need for additional fresh air. By using duct burners, gas-turbine exhaust temperatures can be increased to 1500 to 1600oF (815 to 870oC) with a consequent reduction in the oxygen content of the exhaust gas from 15 percent to 11 percent. Supplementary firing generally doubles the steam output of the heat-recovery boiler by providing a mechanism for varying steam production and matching process-steam demand, independent of the gas-turbine electricity production. Most applications of HRSG’s to gas-turbines of greater than 20MW generate steam at two or three pressure levels. High-pressure steam (600 to 1800 psig, or 4.1 to 12.4 MPa gage) usually drives a steam-turbine generator. Intermediate-pressure steam (200 to 400 psig, or 1.4 to 2.8 MPa gage) is used for process steam in a plant or is injected into the gas-turbine combustor to reduce NO, emissions. Low-pressure steam (5 psig to 120 psig, or 35 to 825 KPa gage) is used for plant processes or feedwater heating in a de-aerator. An increasing number of installations induce intermediate-pressure steam for additional power recovery in the low-pressure stages of an enhanced power output when plant steam demand is low, but electrical demand is high. The heat-recovery steam generator may also incorporate additional water-heating sections for condensate preheating or for high-temperature water for fuel heating or other plant processes. In some locations, air-quality authorities have imposed very stringent requirements for NOx emissions from gas turbines. In many cases, these requirements virtually mandate the use of NOx reduction catalysts in the turbine exhaust steam. These catalyst assemblies operate in a narrow temperature range that is lower than the turbine exhaust-gas temperature. The presence of an HRSG is an asset in the strategy to control emissions since the NOx reduction catalyst may be located in the appropriate temperature zone between sections of heatexchange surface in the boiler. Steam-Generator Designs The basic principles for selecting heat-recovery steam-generating equipment are similar to those for conventional utility and industrial boilers. However, the designer must be aware of the entire system arrangement in order to integrate the steam generator properly within the overall plant. Although cycle efficiency and economics generally determine the basic cycle conditions, the designer is typically faced with a matrix of conditions, which determine the optimum design. These conditions include a wide range of thermal performance parameters, dictated by varying ambient conditions and steam load requirements, limitations on capital cost, and restrictions on available space. In pursuing a solution to the demands of a specific application, three aspects ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II

HRSG OPERATION AND MAINTENANCE of the boiler design process dominate: (1) extensive use of externally finned tubing for maximum convective heat recovery, (2) an emphasis on low gas-side pressure loss to limit the gas-turbine fuel-rate penalty associated with increased backpressure on the gas turbine, and (3) distribution of heat-recovery surface in multiple sections to achieve optimum heat transfer at each temperature level through the boiler.
Figure 14: Vertical, Unfired Steam Generator for Recovery of Heat from Gas Turbine Exhaust Boiler Configuration Waste-heat boilers in gas-turbine exhaust service can be configured with gas flow in the horizontal or vertical direction. Vertical gas-flow units permit an arrangement of equipment in the exhaust flow path that occupies less floor space but requires extensive steel support structure. Horizontal gas-flow units generally cover a greater plan area, but afford much better access for maintenance of boiler parts, duct burners, catalyst elements, and other equipment that may be associated with the HRSG.

HRSG OPERATION AND MAINTENANCE Boilers with vertical gas flow usually employ horizontal tubes connected by return bends with the tubes supported at several locations along the length of the tube my tube sheets, as illustrated in the figure above. Most of these applications require a circulating pump in the steam-generating sections of the boiler. The circulating pump ensures uniform distribution of water to multiple parallel steam-generating circuits. Pumps are usually sized to maintain a circulation ratio of 4 to 1 at the maximum steaming condition. Boilers with horizontal gas flow use vertical tubes connected to headers at the top and bottom, as seen in the following figure. The tube and header assemblies may be either top-supported or bottom-supported. Although the tubes are self-supporting in the vertical direction, lateral restraints are required to control gas-flow-induced vibrations. Natural circulation in the steamgenerating sections provides high circulation ratios without the use of pumps.

Figure 16: Temperature Profile of Unfired Heat Recovery Steam Generator with Three Operating Pressure Levels A simplified flow diagram (Figure 17) for a triple-pressure HRSG illustrates the way in which heat-absorbing sections operating at certain temperature levels are located in the gas stream to minimize the amount of heat-transfer surface required. There are ten discrete heat-exchange sections distributed in descending order based on the gas temperature available and the fluid temperature requirements. The two critical temperature differences that influence the amount of heat-transfer surface and the overall steam generated at each pressure level are the: •
Pinch point: The difference between the gas temperature leaving a evaporating section and the temperature at which boiling is occurring (saturated-water temperature).
•
Approach temperature: The difference between the saturated-water temperature in an evaporating section and the incoming feed-water temperature.
The pinch point strongly influences the amount of heat-transfer surface in the evaporating section. Current HRSG designs use pinch points in the 15 to 25oF (8 to 14oC) range. In general, these boilers have 50 percent more surface in the evaporating section than boilers with pinch points of 40 to 50oF (22 to 28OC). The approach temperature also influences the temperatures. Current HRSG economizers have approach temperatures in the 15 to 250oF (8 to 14oC) range at the design point. Many other operating conditions can occur at off-design points, including start-up. Some conditions will result in steaming at the exit of the economizer, such that it acts as evaporative surface.

HRSG OPERATION AND MAINTENANCE Specific provisions to accommodate steaming at levels up to 5 percent of total flow in an economizer include: (1) careful control of water distribution in the last downflow passes of the economizer to cause that portion of the economizer to behave as a forced-circulation evaporator, or (2) configuring the last few passes of the economizer as entirely upflow, with relief by natural circulation into the steam drum. The triple-pressure HRSG temperature diagram shown in Figure 16 illustrates the distribution of heat-exchanger sections and the side of each evaporating bank section. Approach temperatures are illustrated as the difference between the water temperature leaving the last section of each economizer and the saturated-water temperature. Note that the high-pressure economizer is divided into three separate sections to provide appropriate temperature zones for the intermediate-pressure superheater, evaporator and economizer. Typical Construction Features The triple-pressure HRSG shown in Figure 17 illustrates equipment normally included in the scope of supply of the boiler supplier: •
Expansion joint at gas-turbine exhaust interface
•
Single-blade exhaust diverter valve bypass stack with silencer
•
Inlet transition duct with flow corrective devices
•
Duct burner
•
Heat-recovery steam-generator modules steam drums
•
Access ladders and platforms
•
Exhaust stack
Insulation is placed on the inside of all duct sections and boiler casing sections, thereby allowing the use of carbon steel casing plate and stiffeners, and minimizing the thermal growth of the overall boiler structure. A system of internal liner plates protects the insulation from gas flow. These plates are segmented for individual thermal expansion and overlapped in the direction of gas flow. All boiler pressure parts are supported in ways that allow complete freedom for thermal expansion relative to the casing and support structure.

HRSG OPERATION AND MAINTENANCE Fired Steam Generators Supplied with Gas Turbine Exhaust Normally containing 75 to 80 percent of the oxygen found in free atmospheric air, gas-turbine exhaust can concurrently supply to the furnace of a steam generator both sensible heat and oxygen for the combustion of a fuel. The design and operation of such boilers vary considerably, depending upon the ratio of the total exhaust flow to the amount necessary for oxidizing the supplementary fuel needed for a given evaporation. Combustion air preheaters are not used because of the already high level of preheat represented by the 700o to 900oF (370oF to 480OC) temperature of the exhaust gases. Supplementary-fired steam generators (Fig. 24) using most of the oxygen in the turbine exhaust are of the same design and size as units using outside air through forced-draft fans. The stack temperature of such a unit can be dropped economically to within 100o F (55o C) of the incoming feedwater temperature. Since the boiler is sized for a flue gas weight based on fresh air firing, a portion of the gas turbine exhaust is by-passed. This portion of the exhaust is cooled by passing over a separate steam generating bank, to the same temperature as the gasses passing through the boiler, and then proceeds to the final heat recovery in the economizer. In such a cycle, gas turbine and boiler size must be matched closely to obtain a high ratio of feedwater flow to the gas-turbine exhaust flow. Because all gas-turbine/boiler applications involve the recovery of sensible heat, the usual concept of boiler efficiency loses its significance. Customary practice therefore is to evaluate performance of combined-cycle boilers on the basis of stack temperature. The overall station heat balance is determined using the calculated value of fuel fired in the boiler (rather than boiler efficiency as such), in addition to the fuel fired in the gas turbine.

SECTION 2: HRSG SYSTEM DESCRIPTION 2.1 LEARNING OBJECTIVES •
Draw a simplified functional diagram of the HRSG, labeling the major components.
•
Describe the purpose and function of the major components.
2.2 INTRODUCTION (Refer to Pressure Part Diagram, Figure 2-3) This section provides a brief description of the components that make up the Heat Recovery Steam Generator (HRSG). The HRSG consists of three boiler systems at different pressure levels, high pressure (HP), intermediate pressure (IP), and low pressure (LP) and a Reheater. The water/steam and the exhaust gas flow paths are described below, starting from the inlet and following the fluid flow path. Each pressure stage consists of an economizer, evaporator and superheater. The Feedwater is heated in the economizer and fed to the drum. From the drum, water is fed into the evaporator, where a portion is evaporated. The resulting water-steam mixture returns to the drum, where the mixture is separated by means of separators. The saturated steam is fed into the superheater. The water/steam and the exhaust gas flow paths are described in the next section starting from the inlet and following the fluid flow path. The heat-absorbing sections of the HRSG are made up of shop-assembled pressure part modules. These modules can be shipped by truck, rail or barge. Each module is properly braced for shipment. The HRSG finned tubing is made by helically winding solid or serrated fin stock to the walls of bare tubing by means of a low penetration, high frequency resistance welding process. The HRSG evaporator circuits incorporate large steam drums to reduce the potential for water surges normally encountered during cold starts. Dedicated downcomers are used to ensure a proper circulation in each of the evaporator circuits. 2.3 HIGH PRESSURE WATER/STEAM FLOW PATH HP feedwater is supplied to the HP pressure section via the HP stage of the feedwater pump, which extracts feedwater from the Deaerator Storage Tank. The HP Economizer section functions to raise the boiler feedwater to a suitable approach temperature. After passing through the feedwater control, check and stop valves, the HP feedwater enters the HRSG at HP Economizer 4. The water then flows through HP Economizer 4, HP Economizer 3, HP Economizer 2, and then through HP Economizer 1. After leaving HP Economizer 1, the water enters the HP Steam Drum through one feedwater inlet nozzle and continues on to HP Evaporator. Natural circulation is maintained in the HP Evaporator by means of downcomers, which feed the water from the drum through distribution manifolds to the lower evaporator headers. Steam is generated and flows upward in the ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II

HRSG OPERATION AND MAINTENANCE evaporator tubes. The saturated water/steam mixture is conducted from the upper HP Evaporator headers to the HP Steam Drum through risers. The saturated steam is separated from the saturated water/steam mixture by the drum internals (centrifugal separators, corrugated dryers, and dry box) and then exits the top of the HP Steam Drum through the saturated steam outlets. ( A typical section of steam drum internals is shown in Figure 2-1) The saturated steam leaving the drum passes through HP Superheater 3 and HP Superheater 2. After leaving HP Superheater 2, the steam passes through two HP Desuperheaters in parallel. After leaving the HP Desuperheater, the steam flows through HP Superheater 1. The steam leaves HP Superheater 1 through connecting links where it is combined into the HP Main Steam line. 2.4 REHEATER STEAM FLOW PATH After combining with the IP steam, the cold RH enters the HRSG through Reheater 2. The steam then passes through two RH Desuperheaters in parallel into Reheater 1. The steam leaves Reheater 1 through connecting links where it is combined into the hot Reheat Steam Line. 2.5 INTERMEDIATE PRESSURE WATER/STEAM FLOW PATH After passing through the feedwater control, check and stop valves, the IP feedwater enters IP Economizer 1 then enters the IP Steam Drum through the feedwater inlet nozzle. This flow continues through the IP Evaporator. Natural circulation is maintained in the IP Evaporator by means of downcomers, which feed the water from the drum through distribution manifolds to the lower evaporator headers. Steam is generated and flows upward in the evaporator tubes. The saturated water/steam mixture is conducted from the upper IP Evaporator headers to the IP Steam Drum through risers. The saturated steam is separated from the saturated water/steam mixture entering the steam drum by the drum internals (centrifugal separators, corrugated dryers, and dry box) and exits the top of the IP Steam Drum through saturated steam outlets. The saturated steam leaving the drum passes through the IP Superheater. The steam leaves the IP Superheater through connecting links where it is combined into the IP Main Steam Line. A portion of the IP Steam can be used as pegging steam for the external deaerator. The IP steam passes through non-return and stop valves and then combines with the cold reheat steam. 2.6 LOW PRESSURE WATER/STEAM FLOW PATH The LP Feedwater takes suction from the Dearerator Storage Tank. The LP Feed water from terminal point (TP-7) passes through the flow orifice, control valve, stop check valve and block valve and enters the LP Drum through the feedwater inlet nozzle. A separate Condensate Feed flows through the Condensate Preheater and on into the External Deaerator Tank. A portion of the water from the Preheater outlet is taken to the Preheater Recirculation Pump suction. It then is being recirculated and mixed with the feedwater entering the Preheater inlet nozzle to increase the temperature of the incoming feedwater prior to entering the External Deaerator. Natural circulation is maintained in the LP Evaporator by means of downcomers, which feed the water through distribution manifolds into the lower evaporator headers. Steam is generated and flows upward in the evaporator tubes. The saturated water/steam mixture is conducted from the upper LP Evaporator headers to the LP Drum through risers. The saturated steam is separated ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II

HRSG OPERATION AND MAINTENANCE from the saturated water/steam mixture entering the steam drum by the drum internals (corrugated dryers, and dry box) and exits the top of the LP Drum through saturated steam outlets. The saturated steam leaving the drum passes through the LP Superheater. The steam leaves the LP Superheater through connecting links where it is combined into the LP Main Steam line. 2.7 GAS SIDE FLOW PATHS The exhaust gas that enters the HRSG will pass by the pressure part sections of the HRSG, heating the steam or water inside the tubes. The exhaust gas will pass across the pressure part sections in the following order: HP Superheater 1 - Reheater 1 - HP Superheater 2 - Reheater 2 - HP Superheater 3 - HP Evaporator 1 – HP Evaporator 2 The gas then passes across the remaining pressure parts sections in the following order: IP Superheater - HP Economizer 1 - LP Superheater - HP Economizer 2 - IP Evaporator - HP Economizer 3 - IP Economizer 1 - LP Evaporator - HP Economizer 4 - Condensate Feedwater Preheater. The exhaust gas will leave FW Preheater and exit the HRSG through the main exhaust stack. Some changes may occur in the pressure sections such as surface oxidation. In addition, normal operation of the boiler may result in some bowing of the tubes due to normal manufacturing tolerances. Both of these conditions are considered normal and are expected. 2.8 SCR – SELECTIVE CATALYTIC REDUCTION SYSTEM (Not used at Nubaria) N/A 2.9
START-UP VENTS
The HP main steam outlet piping incorporates a remotely operated vent valve at a location just upstream of the main steam outlet check valve. This valve is used to vent air and non-condensables from the system during start-up and to relieve excess steam pressure during steam system transients. 2.10
SKY VENTS
The sky vents system consists of a shut off manual valve, a control valve, the flow orifice and the steam silencer. Whenever the control valve opens, steam releases into the atmosphere. The flow orifice determines the steam flow to be added to the total steam flow for drum level control. The steam silencer reduces the noise through this vent line. 2.11

HRSG OPERATION AND MAINTENANCE 2.15
OVERALL PROJECT
A gas turbine combined with a triple-pressure HRSG with reheat and HP/IP/LP steam turbines form the combined cycle plant at the Nubaria Power Station. The HRSG utilizes the hot exhaust gas from the gas turbine to generate steam in three cycles: high pressure, intermediate, and low pressure. Steam produced is directed to the steam turbine. The HRSG is also equipped with a reheater section to reheat steam, which has passed through the HP turbine and direct it to the IP turbine. The Predicted Performance data provided at the end of this section addresses multiple operating conditions for the HRSG. Ambient conditions ranged from a modest 15 °C (59 °F) on up to 40 °C (104 °F) were reviewed. Maximum HP steam flow 71.19 Kg/s occurs at 129.2 bar and 567.7 °C. 2.16
SCHEMATIC OVERVIEW
Figure 2-3 (At the end of this section) provides an overview of the fluid flow paths, both series and parallel, which integrate the HRSG into the larger system of separators, coolers, preheaters, pumps, and turbines. Rather than simply being a radiator, the integration of this complex heat transfer system results in one of the most cost effective and efficient electric power production units in the world.

HRSG OPERATION AND MAINTENANCE
SECTION 3: AUXILIARY SYSTEMS AND EQUIPMENT 3.1
LEARNING OBJECTIVES
Describe the purpose, function and basic operation of the auxiliary system and components of the HRSG. 3.2
SAFETY VALVES
Safety valves are devices that protect the steam and water circuits of the boiler against accidental over pressurization. They provide the final protection against pressure part damage when other means, such as control and interlock systems fail or cannot react fast enough. The A.S.M.E. Boiler and Pressure Vessel Code states that safety valves are required on every pressure vessel. The boiler code also requires that the safety valves have a total steam relieving capacity at least equal to the rated full load steam flow of the boiler. 3.2.1 Description Each safety valve consists of a valve disc and seat, which form the seating surfaces. The disc is attached to the valve stem, called spindle, which extends up through the valve body. See Figure 3-11. A spring is used to provide the necessary force to hold the disk against the valve seat until the steam pressure below the disk forces the valve open, overcoming the spring compression. The compression screw is used to adjust spring compression or the popping pressure at which the safety valve opens. Upper and lower adjusting rings are provided inside the valve body near the valve disc and seat. The upper adjusting ring is used to adjust the “blowdown” or the difference between the valve opening and closing pressure. The lower adjusting ring is provided to obtain a quick popping action and to cushion the closing of the valve.

HRSG OPERATION AND MAINTENANCE 3.2.2 Hydrostatic Test Plugs and Valve Gags Hydrostatic test plugs are installed between the valve disc and seat for two purposes. •
To protect the valve seating surfaces during shipment.
•
To increase spring compression to prevent the valve from opening during initial hydrostatic testing.
These plugs must be removed before initial valve setting during boiler start-up. Safety valve gags prevent the safety valve from opening during hydrostatic tests and are also used when setting safety valves and when making valve adjustments. A typical Safety Valve Gag is shown in Figure 3-2.
NOTE: Under no circumstances should gags be left on during normal operation.

HRSG OPERATION AND MAINTENANCE 3.2.3 Safety Valve Operation Steam pressure in the drum or header is applied directly to the valve disc through the inlet nozzle. When the popping pressure is reached the steam pressure overcomes the force of the spring and the disc and spindle is pushed up opening the valve. This is called the “full life” position. The reaction force of the steam blowing between the disc and the seat holds the valve open. With the safety valve open the system steam pressure drops. When the spring pressure overcomes the steam pressure, the disc and spindle return to the closed position. Figure 3-3 shows a typical safety valve in both the open and closed positions.

HRSG OPERATION AND MAINTENANCE 3.2.6 Exhaust Piping Arrangement The exhaust from the safety and the relief valves are not attached to the building steel, and are free to move inside the vent pipe that vents the steam to the atmosphere. Only the vent pipe is attached to the building steel framework. Drains from the drip pan and exhaust vent pipe remove condensate. Vent piping is not connected to the valve body and should discharge the steam to a safe location. Proper drainage installation will prevent condensate buildup in the valve body and drip pan.

HRSG OPERATION AND MAINTENANCE 3.3
WATER LEVEL GAUGE
The primary function of water gauges and indicators is to provide the operator with a readily visible means of monitoring the water level within the steam drums at all times. Proper water level in steam drums is crucial during HRSG operation for the following reasons: •
Too low a water level in a steam drum may cause reduction and/or loss of circulation in the tube circuits.
•
Too high a water level will reduce the effectiveness of the steam separators and dryers in the drums causing water carry-over to the superheating tube assemblies.
3.3.1 Location The water gauge level indicator is attached to the end of each steam drum to allow visual monitoring of the steam drum water level. In accordance with the A.S.M.E. code for power boilers, a minimum of two (2) steam drum level indicators must be in service on the boiler steam drum at all times. In addition to the water level gauge, three level transmitters are also attached to the steam drum. 3.3.2 Description Normal operating water level in the steam drum is approximately the centerline of the drum. (See Figures 4-3, 4-4 and 4-5 for Drum Level Setpoints for the LP, IP, and HP Drums). The centerline of the gauge glass is located slightly below the normal water level (NWL) to correct for sub-cooling effects during operation. The gauge assembly typically consists of a steel body with flat glass faces. The tie-bar (necessary on only one end of these drums) includes upper and lower valves, which provide isolation of the water gauge for servicing and a connection for draining. This type of gauge requires a rear positioned illuminator. The illuminator is a device, which provides an electric lamp source for better viewing. The centerline of the water gauge glass is location slightly below the normal water level to correct for sub cooling effects during operation. Sub cooling is a condition when the water in the lower gauge glass connection is cooler than the water in the steam drum. The level in the water gauge will be lower than the actual level in the drum because the density in the gauge is greater than that of the steam drum. Placing the gauge centerline below the drum centerline compensates for the density difference between the water gauge and the steam drum. The water gauge body is attached vertically to a support column, which is connected to the water and steam sides of the steam drum through connections provided on the end of the steam drum. The water gauge is assembled from glass along with the necessary gaskets for sealing against drum pressure and temperature. ALSTOM Power Copyright 2004 Santan Expansion Project

HRSG OPERATION AND MAINTENANCE The drum water level is visible in the water gauge at all times, no matter how rapidly the water may rise or fall within the steam drum. This enables the operator to take an accurate reading at any time during operation. 3.3.3 Operation Water gauges use the principle of liquid seeking a level between two connected vessels. The top of the gauge glass is connected to the steam space of the drum. The bottom of the gauge connection is below the normal water level of the drum. This arrangement will allow the liquid in the gauge to rise to a level indicative of the level in the steam drum. Water in the gauge glass is cooler than water in the vessel and is denser. This results in a gauge water level, which is lower than the true water level in the vessel. Although this is compensated for, the operator must be cautioned to look for any other conditions, which may also lead to variations in gauge levels, such as: •
Plugged connection lines that will cause abnormal level readings, which can be corrected by proper lowdown.
•
Steam leaks that will reduce the pressure in the steam space of the gauge and will cause the water level in the gauge to rise. Steam leaks should be properly corrected to prevent damage to the gauge gasket-seating surface as well as to prevent false readings.
3.3.4 Water Gauge Blowdown The procedure for water gauge blowdown is as follows: a. b. c. d. e. f. g.
Make sure that the gauge glass can be isolated and drained separately from the transmitter. (See Figure 3-5) Close the upper and lower gauge valves. Open the drain valves and drain the gauge. Crack open the upper valve and allow the rush of steam to pass through the gauge, cleaning the glass. Close the upper valve. Inspect the gauge for cleanliness and if necessary repeat 3 and 4. Close the drain valve and slowly open the upper and lower gauge valves.
The gauge should now be clean and ready for service.

•
Describe the monitoring and supervision provided for on the HRSG and supervision provided for on the HRSG and list what parameters will initiate a unit Gas Turbine run back or possible trip.

CONCEPT for LP, IP, and HP DRUM LEVEL CONTROLS
The Feedwater control system modulates the rate of feedwater flow to the boiler to match the steam demand leaving the boiler. A relatively constant drum level is maintained by the control system throughout the operating load range of the boiler. Controlled steam drum level is important for two significant reasons. •
An excessively low water flow will expose boiler tubes resulting in overheating of the tube metal.
•
An excessively high water level will interfere with the steam-water separating equipment in the steam drum. Water separation becomes less effective and some water will be entrained in the steam leaving the drum. Water is then carried over with the steam, resulting in damage to plant equipment.
When load demand changes occur, the amount of steam required by the turbine/process changes. The flow of feedwater to the boiler must also change to meet the new load demands. The drum level control system provides for the necessary balance between the turbine and the boiler. An accurate measure of the balance between boiler fluid input and steam flow output is steam drum level. The feedwater control system sustains this balance by maintaining the proper fluid storage level within the boiler at all times. 4.2.1
Drum Level Control
HP Drum Level Control (Drum level will be corrected by the drum pressure). Normal Level: The drum level control will regulate the rate of feed water flow to maintain a proper drum level throughout the operation range of the steam generator. To get the maximum benefit from a three-element system, the feed water flow should be proportional to steam flow with reset action on drum level which means that the mass of feed water entering should always be equal to the mass of steam leaving, with continuous corrections made for deviations from level set points.

Dearator Storage Tank and Condensate Preheater Condensate Preheater Bypass Operation
When operating the HRSG Unit with high sulfur fuel, the Condensate Preheater should be bypassed. To bypass the Condensate Preheater, the Condensate Preheater Feedwater Stop Valve (HV-002) is closed and the Condensate Preheater Bypass Stop Valve (HV-003) is opened, resulting in all of the flow bypassing the Condensate Preheater. Online Switch Over to Engage Condensate Preheater Recirculation
In order to accomplish an on-line switch over while the HRSG is in operation and reengage the Condensate Preheater Recirculation, turn on the Condensate Preheater Recirculation Pump (PMP-040) and open the Recirculation Pump Discharge Control Valve to 100% open. To prevent thermal shock of the Preheater manifold, keep the Condensate Preheater Bypass Stop Valve (HV-003) open for 15 minutes after opening the Condensate Preheater Feedwater Stop Valve (HV-002). Set the Feedwater Heater Recirculation Control in AUTO mode. Pegging Steam Control
Pegging steam flow from the IP and LP Systems will be controlled by the Pegging Steam Control Valves (PV-001D, PV-002D and PV-003D) to maintain the Deaerator Storage Tank Pressure (PIT-001D and PIT-002D) at a set point established by the heat balance and process requirements.

HRSG OPERATION AND MAINTENANCE 4.2.2
Description
The feedwater control system is a control loop that, when in automatic maintains a balance of feedwater entering the boiler with the amount of steam leaving the boiler. The control system also keeps the volume of boiler water within the steam drum to an established set point level during operation. The feedwater control system is referred to as a “three-element control system” because three system measurements, or variables, are used to determine the required feedwater rate to the boiler. The three elements monitored are: •
Drum level
•
Feedwater flow
•
Steam flow
The three monitored elements, steam flow, steam drum level and feedwater flow, are measured and converted into electrical signals. The signals are transmitted as feedback control signals, to the control room. The use of three different elements provides a quick response when transients, or changes, occur during unit operation. The Feedwater control system is an analog control system. variable. Feedwater flow is the manipulated variable. 4.2.3
Drum level is the controlled
Principles of Operation
Drum level is related to, but is not a direct indicator of the quantity of water in the steam drum. Under different and varying steam loads, the steam bubbles occupy a different and varying volume of steam and water mixture. The mixture volume is related to the pressure in the steam drum. Two conditions can affect accurate drum level control. Figure 4-1 depicts these two conditions, called Shrink and Swell. 4.2.4
Shrink
In the case of shrink, an increase in pressure in the steam drum due to decreased steam flow results in the water in the steam drum dropping to a temperature lower than saturation. This will cause some of the steam bubbles to condense back into water and others to contract under the increased pressure. The level in the steam drum decreases. The amount of level decrease, or shrink, is dependent on the steam pressure within the steam drum. The greater the rise in steam pressure, the more the level will decrease. The effect shrink produces is a decreasing level even though less mass is actually leaving the steam drum.

4-5
HRSG OPERATION AND MAINTENANCE 4.2.5
Swell
If the steam pressure within the drum decreases due to an increase in steam flow, the water temperature within the drum is raised above the saturation temperature for that pressure. This causes some of the water to form additional steam bubbles, and the steam bubbles that are raising in the riser tubes will also expand. To maintain the continued flow of water through the riser tubes, the drum level will increase (swell). The amount of level rise is dependent on the steam pressure within the steam drum. The more the steam pressure decreases the greater the rise in drum level. The result of swell is that the level in the steam drum increases even though additional mass is actually leaving the steam drum.

HRSG OPERATION AND MAINTENANCE 4.2.6
Functional Level Control Operation
This use of the steam flow and feedwater flow signals minimizes the effects of shrink and swell. The three-element control system provides a smoother control of the drum level. (Figure 4-2).
Figure 4-2: Three Element Control
With no load changes, steam flow and feedwater flow should be equal to maintain a steady steam drum water level. The steam flow and feedwater flow signals are compared with each other to develop an error signal. This is the flow error (FR) signal. The measured drum level drum level is then compared with the flow error to provide a total error or level-flow error (LE) ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II
Revision: 0 04/02/05
4-7
HRSG OPERATION AND MAINTENANCE signal that is then sent to the level controller (LC). The total error is compared with the setpoint to provide the error signal that positions the feedwater control valve. •
In a swell condition (water level is increasing), the water level signal alone will call for less water. However, this would starve the boiler because the swell condition is caused by an increased steam flow (decreased steam pressure), which means more water is needed. By comparing the water level error with the steam flow, the amount of increased water flow called for by the steam and water flow error is balanced against the decrease in flow called for by the rising drum level. This action will continue to occur until steam pressure is restored to normal by stabilizing load demand at a new level. As the water level decreases to normal, more water is allowed to enter the boiler until feedwater flow equals steam flow.
•
The drum level signal is density compensated to generate a corrected drum level signal to the drum level controller.
•
To control swell during start-up, drum levels are maintained at a lower control level, just above its low water alarm setpoint, until steam flow reaches 10% of full flow for that system.

HRSG OPERATION AND MAINTENANCE
SECTION 5: OPERATION 5.1 • •
5.2
LEARNING OBJECTIVES Given a start-up condition (cold, hot) describe the actions and criteria needed to proceed up to full load. Given an abnormal condition, describe the proper procedures to bring the condition back to normal state. HRSG BOILER OPERATIONAL OVERVIEW
These procedures are intended to serve as a guide during the initial operating stages of a Heat Recovery Steam Generator (HRSG). They include the proper operating sequences for the steam generator and auxiliary equipment furnished by ALSTOM Power inc. Refer to the Piping and Instrumentation Diagram. The sequential procedures do not include detailed reference to equipment not furnished by ALSTOM Power inc., such as the feed pumps, or the gas turbine, etc. Because the steam generator is only one part of the power plant, and all equipment must operate in unison, specific procedures and detailed values cannot be included in this manual. As operating experience is gained and the controls are fine-tuned, the characteristics and operating requirements of the unit will become apparent. Refer to manufacturer's instructions for further operating details for specific equipment supplied by ALSTOM Power inc. 5.3
COMPLETION OF MAINTENANCE PRIOR TO OPERATION
Check the HRSG to make sure that all maintenance work has been completed, all tools and debris have been removed, the handhole plates and manhole covers have been installed and secured, and all access doors have been installed and secured. Check the safety valves to see that the gags have been removed, the lifting levers have been replaced, and the valves are not fouled or hung up. NOTE: Some equipment such as Valves, Instrumentation, Pumps, etc. mentioned in this manual may not be part of Alstom Power Scope of supply, so it may not shown on the Alstom Power’s P&ID drawing or referred documents. 5.4
INITIAL FILLING
This section describes the recommended procedure for fiIIing an empty HRSG with water. If the unit is hot, filling of a pressure level system with cold water should not be initiated until the drum metal temperature for that pressure level has cooled to within 56°C (100°F) of the incoming feedwater temperature. Filling should be done slowly, with the feedwater control valve at 10% open, to avoid severe temperature strains. Otherwise, damage may result due to relatively cool water coming into contact with heated pressure parts. Also, since deposits of solids in a superheater can cause corrosion or inhibit heat transfer, introduction of solids by carryover of boiler water from the drum during filling, hydrostatic testing or chemical cleaning must be avoided.

CONDENSATE PREHEATER OPERATION
Condensate Preheater Recirculation Operation The Condensate Preheater Recirculation System Functional Group should be switched ON, during normal operation of the gas turbine on Natural Gas fuel. During normal, base load operation of the HRSG, when the GT is using Natural Gas, the Condensate Preheater Recirculation Pump (PMP-040) is switched ON when the condensate feedwater temperature is < 51.7°C (125°F). The pump is switched OFF automatically when the condensate feedwater temperature is > 55°C (131°F). The Condensate Preheater Feedwater Stop Valve (HV-002) is positioned in the fully-opened position and the Condensate Preheater Bypass Stop Valve (HV-003) Is positioned in the fully-closed position. NOTE: A minimum temperature difference of approximately 2.5°C must be maintained between the saturation temperature in the Deaerator based on the operating pressure (PIT-001D and PIT-002D) and the incoming feedwater temperature (TE-066A and TE-066B) in order to ensure proper operation of the Deaerator. CAUTION: The Condensate Preheater Recirculation Pump (PMP-040) must never be run with suction and discharge valves closed. Damage to the pump will occur if there is no water flow through the pump. Ensure that the Minimum Recirculation Stop Valve (V-062) is fully open before starting the pump. 5.7
START-UP FROM A COLD CONDITION
This section describes the recommended procedure for starting the HRSG from a cold condition with no pressure in the HP, IP and LP boiler sections. Proceed as follows: 1. Purge the HRSG in accordance with NFPA 85, Chapter 8.9.2 (Combustion Turbine Exhaust Systems) guidelines. It is understood that purging is accomplished by using air at ambient temperatures. The ambient air temperatures during a normal purge cycle will not have any damaging effect on any of the HRSG components. 2. Align all HRSG valves as shown under the column labeled “START FROM COLD” on Tables 1 through 6. NOTE: Some of the following procedures are redundant to what is shown on Tables 1 through 6. This is done to emphasize the importance of performing these procedures. 3. Open the Stack Damper before rolling the Gas Turbine. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II

The RH Desuperheater Spraywater Power Block Valve (HV-700) is in ‘AUTO’. NOTE: Although desuperheating is not required except at peak turbine load, it is good practice to have the control station available whenever the unit is operating. 6. The following Drain Valves are in AUTO: HP Superheater 1 Drain Valve (HV-284), HP Superheater 2 Drain Valve (HV-282), HP Superheater 3 Drain Valve (HV-280), Allow any condensate in these sections to drain. 7. The following Drain Valves are in AUTO: Reheater 1 Drain Valve (HV-765), Reheater 2 Drain Valve (HV-760), IP Superheater Drain Valve (HV-580) Allow any condensate in these sections to drain. 8. The LP Steam Outlet Drain Valves (HV-948 and HV-949) are in AUTO. Allow any condensate to drain. 9. Prior to start up, reset the water level set points in the feedwater control system to ensure that the water levels in the HP, IP, and LP Drums and Deaerator Storage Tank are just above the Cold Start-up NWL (see Tables 7 through 10). Use the HP Evaporator (HV-180), IP Evaporator (HV-480) and LP Evaporator (HV-825) Intermittent Blow-off Valves as necessary to reduce water levels. 10. Open the HP Feedwater Stop Valve (HV-102), IP Feedwater Stop Valve (HV-400) and LP Feedwater Stop Valve (HV-800). 11.

HRSG OPERATION AND MAINTENANCE 14. Close the LP Main Steam Outlet Stop Valve (HV-919) and open the LP Steam Startup Vent (FV-915). NOTE: When starting the second gas turbine/HRSG train, with the first train already operating, the HP Main Steam Outlet Stop Valve (HV001), and the LP Main Steam Outlet Stop Valve (HV-919) shall remain closed until the pressure is within 5% and temperature is within 28°C of downstream piping. After permissives clear and stop valves open, the NRV in the respective lines will open once the pressures match and will then begin admitting steam. 15. If needed, restart feedwater pumps and ensure that pumps are running and all feed system valves are lined up. (See ‘START FROM COLD’ on Tables 1 through 6.) 16. Allow gas turbine exhaust flow to the HRSG by starting the gas turbine. 17. While the steam generator is being brought up to pressure, all cold steam piping should be gradually heated and drained of condensate. The HP Startup Vent Valve (HV-342), RH Steam Outlet Startup Vent Valve (FV-780), IP Startup Vent Valve (HV600), and the LP Startup Vent Valve (FV-915) must stay opened to insure a positive flow of steam which will reduce thermal expansion. To warm the piping downstream of ALSTOM Power scope, open the bypass valve on the HP Main Steam Outlet Stop Valve (HV-001A), the bypass valve on the LP Main Steam Outlet Stop Valve (HV-919A). Next, open a drain or vent downstream of ALSTOM Power scope to allow the steam from the bypass valve to warm the piping. Ensure that all steam piping downstream of the boiler piping is drained prior to admitting steam. NOTE: When starting the second gas turbine/HRSG train with the first train already operational, the bypass valves on the Main Steam Outlet Stop Valves are used to warm piping. 18. Once the LP steam lines have been properly warmed, the LP steam section is “on line” with steam ready to be introduced to the Deaerator. Open the LP Main Steam Stop Valve (HV-919) and close the bypass (HV-919A). The LP Startup Vent Valve (FV-915) will modulate open / closed in order to maintain the LP Steam Outlet Pressure (PIT-915A and PIT-915B) at 4.19 barg (5.20 bara). 19. Warm the Pegging Steam Lines and drain the lines of any condensate by opening the following valves: Low Range LP Pegging Steam Drain Valve (HV-072D). High Range LP Pegging Steam Drain Valve (HV-004D). IP Pegging Steam Drain Valve (HV-008D). Close the Drain Valves after a period of at least 5 minutes. NOTE: When starting the second gas turbine/HRSG train with the first train already operational, the Pegging Steam Lines will not require warming. For Startup on Natural Gas Operation: 20. Modulate open / closed the Low Range Pegging Steam Control Valve (PV-002D) to maintain Deaerator Storage Tank Pressure (PIT-001D and PIT-002D) at 0.99 barg (2.00 bara).

HRSG OPERATION AND MAINTENANCE When the Low Range Pegging Steam Control Valve (PV-002D) has reached 100% open and the Deaerator Storage Tank Pressure (PIT-001D and PIT-002D) falls below 0.99 barg (2.00 bara), this indicates that the required pegging steam is more than the available steam from the Low Range LP Pegging Steam Control Valve (PV002D). Switch over control of the pegging steam flow to the High Range LP Pegging Steam Control Valve (PV-001D). Completely close the Low Range LP Pegging Steam Control Valve (PV-002D). Modulate open / closed the High Range LP Pegging Steam Control Valve (PV-001D) to maintain Deaerator Storage Tank Pressure (PIT-001D and PIT-002D) at 0.99 barg (2.00 bara). The High Range LP Pegging Steam Line will automatically be drained of condensate for 5 minutes using the High Range LP Pegging Steam Drain Valve (HV-004D) prior to opening the High Range LP Pegging Steam Control Valve (PV-001D) if the line has been out of service for at least one (1) hour. When the required pegging steam is more than the available LP steam, the IP Pegging Steam Control Valve (PV-003D) is to be enabled and modulated open / closed in conjunction with High Range LP Pegging Steam Control Valve (PV-001D) to maintain Deaerator set pressure. The IP Pegging Steam Line will automatically be drained of condensate for 5 minutes using the IP Pegging Steam Drain Valve (HV-008D) prior to opening the IP Pegging Steam Control Valve (PV-003D) if the line has been out of service for at least one (1) hour. NOTE: The IP Pegging Steam Control Valve (PV-003D) is being used to maintain the Deaerator Storage Tank pressure at 0.99 barg (2.0 bara) once the High Range LP Pegging Steam Control Valve (PV001D) has reached 70% of the fully open position. During startup, control setpoint for Deaerator Storage Tank Pressure (PIT-001D and PIT-002D) will be set at 0.99 barg (2.00 bara). For Startup on Solar Fuel (Oil) Operation: 21. Modulate open / closed the Low Range Pegging Steam Control Valve (PV-002D) to maintain Deaerator Storage Tank Pressure (PIT-001D and PIT-002D) at 3.49 barg (4.50 bara). When the Low Range Pegging Steam Control Valve (PV-002D) has reached 100% open and the Deaerator Storage Tank Pressure (PIT-001D and PIT-002D) falls below 3.49 barg (4.50 bara), this indicates that the required pegging steam is more than the available steam from the Low Range LP Pegging Steam Control Valve (PV002D). Switch over control of the pegging steam flow to the High Range LP Pegging Steam Control Valve (PV-001D). Completely close the Low Range LP Pegging Steam Control Valve (PV-002D). Modulate open / closed the High Range LP Pegging Steam Control Valve (PV-001D) to maintain Deaerator Storage Tank Pressure (PIT-001D and PIT-002D) at 3.49 barg (4.50 bara). The High Range LP Pegging Steam Line will automatically be drained of condensate for 5 minutes using the High Range LP Pegging Steam Drain Valve (HV-004D) prior to opening the High Range LP Pegging Steam Control Valve (PV-001D) if the line has been out of service for at least one (1) hour. When the required pegging steam is more than the available LP steam, the IP Pegging Steam Control Valve (PV-003D) is to be enabled and modulated open / closed in conjunction with High Range LP Pegging Steam Control Valve (PV-001D) to maintain Deaerator set pressure.

HRSG OPERATION AND MAINTENANCE (HV-008D) prior to opening the IP Pegging Steam Control Valve (PV-003D) if the line has been out of service for at least one (1) hour. NOTE: While the IP Pegging Steam Control Valve (PV-003D) is being used to maintain the Deaerator Storage Tank pressure at 3.49 barg (4.50 bara) the High Range LP Pegging Steam Control Valve (PV001D) is to be maintained at 70% of the fully open position During startup, control setpoint for Deaerator Storage Tank Pressure (PIT-001D and PIT-002D) will be set at 3.49 barg (4.50 bara). For Startup on All Fuels: 22. When a measurable HP steam flow is established (approximately 10% of full flow), the HP steam section is “on line” and the HP Main Steam Outlet Stop Valve (HV001) may be opened and the HP Startup Vent Valve (HV-342) may be closed. Close the bypass on the HP Main Steam Outlet Stop Valve (HV-001A) if opened for warming the piping. 23. When a measurable IP steam flow is established (approximately 10% of full flow), the IP steam section is “on line” and the IP Startup Vent Valve (HV-600) may be closed. 24. The Condenser is available when the vacuum has been established. At that time, the HRH to Condenser Bypass is ready to be engaged. The RH section is “on line” and the RH Outlet Startup Vent Valve (FV-780) may be closed over a period of 2 minutes. Prior to the Condenser being available, the RH Outlet Vent Valve (FV-780) will modulate open / closed in order to maintain a minimum pressure of 10.99 barg (12.00 bara) at the HRH Outlet (PIT-780A and PIT-780B). Note that the RH Outlet Startup Vent Valve may remain open up to but not exceeding 50% flow rate. 25. Once the LP Turbine is ready to receive steam, the LP Startup Vent Valve (FV-915) may be closed. Note that the LP Startup Vent Valve (FV-915) may remain open up to but not exceeding 100% flow rate. 26. The water level set points in the feedwater control system for the HP, IP, and LP Drums and Deaerator Storage Tank will return to the normal operating water level settings automatically when the respective system steam flow > 10%.

HRSG OPERATION AND MAINTENANCE For Startup on Natural Gas Operation: 27. Prior to beginning the final temperature step increase of the GT while operating at 50% load, complete the following change-overs: •
Disengage the bypass of the Condensate Preheater by turning on the Preheater Recirculation Pump (PMP-040) and opening the Recirculation Pump Discharge Control Valve (TV-040) to 100% open. To prevent thermal shock of the Preheater manifold, keep the Condensate Preheater Bypass Stop Valve (HV-003) open for 15 minutes after opening the Condensate Preheater Feedwater Stop Valve (HV-002). Set Feedwater Heater Recirculation Control in AUTO mode. The amount of recirculation flow should be such that the temperature entering the Condensate Preheater (TE-005A and TE-005B) is at or above the set point of 51.7°C. (Refer to Condensate Preheater Recirculation Operation section.) A minimum temperature differential of approximately 2.5°C must be maintained between the saturation temperature in the Deaerator based on the operating pressure (PIT-001D and PIT-002D) and the incoming feedwater temperature (TE-066A & B) in order to ensure proper operation of the Deaerator.
•
The Low Range LP Pegging Steam Control Valve (PV-002D) should be in AUTO mode so as to be able to control the pegging steam flow to the Deaerator as the total required pegging steam flow decreases. As the temperature of the feedwater entering the Deaerator increases the total amount of pegging steam required while maintaining the Deaerator Storage Tank Pressure (PIT-001D and PIT-002D) at 0.99 barg (2.00 bara) will decrease. Modulate closed as required the IP Pegging Steam Control Valve (PV-003D) first and then the High Range LP Pegging Steam Control Valve (PV-001D). Prior to completely closing the High Range LP Pegging Steam Control Valve (PV-001D), switch control of the LP pegging steam flow over to the Low Range Pegging Steam Control Valve (PV-002D). The Low Range LP Pegging Steam Line will automatically be drained of condensate for 5 minutes using the Low Range LP Pegging Steam Drain Valve (HV-072D) prior to opening the Low Range LP Pegging Steam Control Valve (PV-002D) if the line has been out of service for at least one (1) hour.
28. Once the GT has reached Base Load, change the control setpoint for the Deaerator Storage Tank Pressure (PIT-001D and PIT-002D) to 0.49 barg (1.50 bara). For Startup on All Fuels: 29. Open the following continuous blowdown isolation valves: a. HP Drum Continuous Blowdown Stop Valve (HV-181). b. IP Drum Continuous Blowdown Stop Valve (HV-482). c. LP Drum Continuous Blowdown Stop Valve (HV-827). Blowdown flow should be controlled with the following valves: a. HP Drum Continuous Blowdown Metering Valve (HV-182). b. IP Drum Continuous Blowdown Metering Valve (HV-484). c. LP Drum Continuous Blowdown Metering Valve (HV-829). ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II

Engage the HP to RH Bypass Valve (not in ALSTOM Power scope) to control the HP Steam Outlet Pressure to 58.99 barg (60.00 bara). 13. Open the IP Main Steam Outlet Stop Valve (HV-604), IP Steam Startup Vent (HV600), and the RH Steam Outlet Startup Vent (FV-780). Close the HRH Stop Valve (not in ALSTOM Power scope) and the HRH to Condenser Bypass (not in ALSTOM Power scope). 14. Close the LP Main Steam Outlet Stop Valve (HV-919) and open the LP Steam Startup Vent (FV-915). NOTE: When starting the second gas turbine/HRSG train, with the first train already operating, the HP Main Steam Outlet Stop Valve (HV-001), and the LP Main Steam Outlet Stop Valve (HV-919) shall remain closed until the pressure is within 5% and temperature is within 28°C of downstream piping. After permissives clear and stop valves open, the NRV in the respective lines will open once the pressures match and will then begin admitting steam. 15. If needed, restart feedwater pumps and ensure that pumps are running and all feed system valves are lined up. (See ‘START FROM WARM’ on Tables 1 through 6.) 16. Allow gas turbine exhaust flow to the HRSG by starting the gas turbine. 17. While the steam generator is being brought up to pressure, all cold steam piping should be gradually heated and drained of condensate. The HP Startup Vent Valve (HV-342), RH Steam Outlet Startup Vent Valve (FV-780), IP Startup Vent Valve (HV600), and the LP Startup Vent Valve (FV-915) must stay opened to insure a positive flow of steam which will reduce thermal expansion. To warm the piping downstream of ALSTOM Power scope, open the bypass valve on the HP Main Steam Outlet Stop Valve (HV-001A), and the bypass valve on the LP Main Steam Outlet Stop Valve (HV-919A). Next, open a drain or vent downstream of ALSTOM Power scope to allow the steam from the bypass valve to warm the piping. Ensure that all steam piping downstream of the boiler piping is drained prior to admitting steam. NOTE: When starting the second gas turbine/HRSG train with the first train already operational, the bypass valves on the Main Steam Outlet Stop Valves are used to warm piping. 18. Once the LP steam lines have been properly warmed, the LP steam section is “on line” with steam ready to be introduced to the Deaerator. Open the LP Main Steam Stop Valve (HV-919) and close the bypass (HV-919A) when the system is ready to receive the LP steam.

For Startup on Natural Gas Operation: 27. Prior to beginning the final temperature step increase of the GT while operating at 50% load, complete the following change-overs: •
Disengage the bypass of the Condensate Preheater by turning on the Preheater Recirculation Pump (PMP-040) and opening the Recirculation Pump Discharge Control Valve (TV-040) to 100% open. To prevent thermal shock of the Preheater manifold, keep the Condensate Preheater Bypass Stop Valve (HV-003) open for 15 minutes after opening the Condensate Preheater Feedwater Stop Valve (HV-002). Set Feedwater Heater Recirculation Control in AUTO mode. The amount of recirculation flow should be such that the temperature entering the Condensate Preheater (TE-005A and TE-005B) is at or above the set point of 51.7°C. (Refer to Condensate Preheater Recirculation Operation section). A minimum temperature differential of approximately 2.5°C must be maintained between the saturation temperature in the Deaerator based on the operating pressure (PIT-001D and PIT-002D) and the incoming feedwater temperature (TE-066A & B). This temperature differential is required in order to ensure proper operation of the Deaerator.
•
The Low Range LP Pegging Steam Control Valve (PV-002D) should be in AUTO mode so as to be able to control the pegging steam flow to the Deaerator as the total required pegging steam flow decreases. As the temperature of the feedwater entering the Deaerator increases the total amount of pegging steam required while maintaining the Deaerator Storage Tank Pressure (PIT-001D and PIT-002D) at 0.99 barg (2.00 bara) will decrease. Modulate closed as required the IP Pegging Steam Control Valve (PV-003D) first and then the High Range LP Pegging Steam Control Valve (PV-001D).

CONTROLS AND INSTRUMENTATION
Controls It is beyond the scope of this manual to discuss the design parameters and selection criteria of control systems. Instead, we will review the steam generator dynamics involved in tuning these systems and note problems we have found on actual operating units. When we discuss steam generator control, we are actually referring to the drum level controls; all other controls are supplied by others. The drum level controls will regulate the rate of feedwater flow to maintain a proper drum level throughout the operating range of the steam generator. To get maximum benefit from a three-element system, feedwater flow should be proportional to steam flow with reset action on drum level. This means that pounds of feedwater entering should always equal pounds of steam leaving, with periodic small corrections made to correct deviations from level set points. The best drum level control is achieved through mass flow balance. Instrumentation Even the most sophisticated and well-tuned control systems do not take the place of the judgment of an alert, motivated and trained operator. The only means that an operator has to make his judgements is through adequate and calibrated instrumentation.

HRSG OPERATION AND MAINTENANCE 5.12
SAFETY VALVES
Safety valves serve to protect pressure vessels from overpressure. On superheater outlets they serve the additional purpose of protecting the superheater from overheating in the event of a sudden interruption in steam consumption. The total relieving capacity of the safety valves on a boiler cannot be less than the design steaming capacity. It is a Code requirement that one or more safety valves on the steam drum be set at or below the design pressure of the unit. Any economizer which can be isolated from the boiler must have its own safety valve. The discharge capacity of any superheater safety valve or valves can be included in the total relieving capacity of the boiler, provided there is no way to isolate the superheater. Valves are to be designed to operate without chattering and to obtain full lift at no more than 3% above their set pressure. Valves are to close within 4% of set pressure, but no less than 2% of set pressure. The popping point tolerance shall not exceed: 2 psig for pressures up to 70 psig. 3% for pressures up to 300 psig. 10 psig for pressures up to 1000 psig. 1% for pressures over 1000 psig. ALSTOM Power recommends that all safety valves be lifted to check popping pressure and blowdown prior to annual maintenance outages. During these outages, valves that leaked or had a tendency to simmer or chatter should be disassembled and repaired. During valve testing, it is important to maintain drum level at or below normal water level to prevent water damage to drum valve seats and to prevent high solids boiler water from being drawn into superheaters. Any time a valve is disassembled, its seat should be touched up with a lap and 1000 grit-lapping compound. If the seat is in poor shape, use a carborundum disc first, then progressively finer grits. The following are safety tips and helpful hints: 1. Never set safety valves by holding set pressure and lowering the popping pressure setting with a wrench. This is extremely hazardous. Valve setting changes should be made with the boiler pressure considerably lower than set point. After the wrench adjustment is made the lifting gear should be replaced and boiler pressure should be raised to the new popping point. 2. Ring locking pins can vibrate loose when a valve is relieving. The pins should always be wired to each other except when one pin is removed to make a ring adjustment. 3. Entrained water will cause excessive blowdown on drum valves. Set drum valves with the drum water level a few inches below normal water level, if possible. 4. A rule of thumb: Vent pipes should be 2 inches larger in diameter than the valve discharge pipe. 5. The discharge pipe should extend no more than 14 inches into the vent pipe from the bottom of the drip pan. 6. A safety valve seat can be damaged by debris and water, which enters the valve body through the vent pipe. This debris is blown around when the valve lifts. Covering the vent pipe with a plastic bag can eliminate the problem. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II

HRSG OPERATION AND MAINTENANCE 7. It is occasionally necessary to mount a vent pipe rigidly to the discharge elbow. This should be done only when there is no alternative. Care should be taken that the vent pipe is cut off square, not on the bias. 8. Do not exceed five pops on a valve. If more pops are required, allow valve to cool before proceeding. 9. Do not make adjustments on first pop. Always evaluate the necessary adjustment from two pops. 10. When popping a valve, always have the cap and drop lever assembly in place with a rope affixed. If the valve begins to chatter, it can be manually popped before the seating surfaces are damaged. 11. Observe the popping pressure on a suitable gauge mounted in the proximity of the valve being tested. A second gauge, preferably a dead weight gauge, should be used to validate the calibration of the observed gauge. 5.13
FW PREHEATER BYPASS OPERATION
When operating the HRSG Unit with Distillate Oil, the FW Preheater should be bypassed. To bypass the FW Preheater, ensure you isolate the LP Feedwater Stop After Bypass Valve (YVD06). Ensure the FW Preheater Bypass Isolation Valves (ISV-D720A and ISV-D720B) are open and set the FW Preheater Bypass Modulating Valve in manual (or auto).
5.14
EMERGENCY PROCEDURES
High Water Level Abnormally high water levels should be avoided, as it may lead to carry-over and even priming. In the event of a high water level, there will be a high drum level alarm. Proceed as follows: 1. Isolate the feedwater supply for the appropriate drum using the HP Feedwater Control Valve (LV-100) and HP Feedwater Stop Valve (HV-102), IP Feedwater Control Valve (LV-430) and IP Feedwater Stop Valve (HV-400), LP Feedwater Control Valve (LV-801) and LP Feedwater Stop Valve (HV-800) and Condensate Preheater Outlet Control Valve (LV-064), Condensate Preheater Feedwater Stop Valve (HV-002) and Condensate Preheater Bypass Stop Valve (HV-003) as required. 2. Close the Bypass Stack Diverter Damper to HRSG using Normal Closing Speed (60 seconds). Damper may be reopened once the alarm clears, the cause of the alarm has been corrected and the GT is operating at or below 20% load. See Simple to Combined Cycle Operation for details. 3. Blowdown the appropriate drum until the water level is at the normal level. Use the HP Intermittent Blow-off Valve (HV-180), IP Intermittent Blow-off Valve (HV-480) and LP Intermittent Blow-Off Valve (HV-825) as required. The Intermittent Blow-off Valves may be used when the HRSG is operating at any pressure in order to reduce the drum water level. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II

5-19
HRSG OPERATION AND MAINTENANCE 4. Isolate the steam outlet for the appropriate drum using the HP Main Steam Outlet Stop Valve (HV-001), IP Main Steam Outlet Stop (HV-HV-604) and the LP Main Steam Outlet Stop Valve (HV-919) as required. Open Superheater Drain Valves for appropriate drum using HP Superheater Drains (HV-284, HV-282 and HV-280), IP Superheater Drain (HV-580) and LP Superheater Drain (HV-948) as appropriate. 5. If the alarm has not cleared within 2 minutes and the Bypass Stack Diverter Damper is not completely closed to HRSG, initiate trip of gas turbine. 6. Investigate the water conditions (alkalinity and solids). Low Water Level If the water level falls out of sight in the water gauge, due to failure of the feedwater supply or neglect of the operator, appropriate action should be taken at once. The only exception is in the case of momentary fluctuations that might occur with extraordinary changes in load. Any decision to continue to operate, even if only for a short time at a reduced rating, would have to be made by someone in authority who is thoroughly familiar with the circumstances that led to the emergency and positively certain that the water level can be restored immediately without damaging the boiler. In the absence of such a decision: 1. Close the Bypass Stack Diverter Damper to HRSG using Normal Closing Speed (60 seconds). If the alarm does not clear within 2 minutes, initiate trip of the gas turbine. If the alarm is cleared within 2 minutes and if the cause of the alarm is identified and corrected, the Bypass Stack Diverter Damper may be reopened once the GT is at or below 20% load. See Simple to Combined Cycle Operation for details. 2. Isolate the steam outlet for the appropriate drum using the HP Main Steam Outlet Stop Valve (HV-001), IP Main Steam Outlet Stop (HV-604) and the LP Main Steam Outlet Stop Valve (HV-919) as required. 3. If the condition has not been stabilized and gas turbine trip has been initiated, allow HRSG to cool so that it may be inspected for damage if required. After correcting the cause, the unit may be restarted. CAUTION: Do not attempt to add water until the steam generator has cooled down sufficiently to where the drum metal temperatures are within 56°C (100°F) of the feedwater temperature; otherwise, damage may result due to relatively cool water coming in contact with heated pressure parts.
Tube Failure 1. Immediately secure the gas turbine exhaust flow. 2. Secure unaffected sections of HRSG according to “Securing to Warm Lay-up Condition” instructions. 3. Isolate and drain affected sections of HRSG according to “Securing to Drain” instructions.

HRSG OPERATION AND MAINTENANCE Loss of Feedwater Supply The loss of feedwater supply is a rare occurrence in a properly maintained steam plant. However, loss of the feedwater supply can happen and it is to be treated as an extreme emergency. A steady persistent drop in the steam drum level indicates problems with the feed pump, feed pump recirculation control, steam generator feedwater valve control or a tube leak. By quickly comparing system pressures and flows with data taken at comparable loads during normal operation, the operators should be able to identify the problem area. If feedwater flow is increasing relative to steam flow and the drum water level is still falling, a tube leak can be assumed. Secure the gas turbine exhaust flow and proceed with tube failure emergency procedures (see Emergency Procedures – Tube Failure section for details). For the HP Drum, an alarm will sound when the drum water goes to the low level. At the low low HP Drum level the gas turbine exhaust flow should be secured. If the problem is with the feed pump or controls, restrict steam generator steam flow to balance the ability of the crippled feedwater system to maintain drum level. If it is not possible to stabilize drum levels by reducing load, secure the gas turbine exhaust flow and bottle up the steam generator, keeping all vents closed. When the feedwater system is repaired, restart the unit as detailed under the procedure titled “Start-Up From A Warm Condition”. In any case, the first consideration must be the protection of the steam generator pressure parts from operation with low water. As is true of any emergency situation with a steam plant, events do not always follow an orderly pattern. The procedures above may or may not fit the pattern for every circumstance. The intent is to emphasize what should be done in order to protect the steam generator and bring the plant back in operation as soon as possible.

HRSG OPERATION AND MAINTENANCE
1.
INTRODUCTION The main objectives of water chemistry control are to insure the long term integrity of the materials of construction and the successful operation of the boiler-turbine power cycle. The particular types of chemical treatment may very depending on many factors such as the variety of materials, operating conditions, system design, etc. The treatment of the feedwater and boiler water is beyond the control of this company. This company does not assume the responsibility for water treatment and control. This is in accordance with practices established by the American Boiler and Affiliated Industries Standards Committee. The company does however, provide water chemistry guidelines that reflect good industry practices. These guidelines are generally in accordance with published guidelines from EPRI, VGB, ASME, as well as ABMA (American Boiler Manufacturers Association). One notable exception is that the feedwater and boilerwater qualities reflect the steam purity requirements specified by the steam turbine and gas turbine (if steam or water injected) supplier as opposed to those provided in the ABMA guidelines. Feedwater chemistry control is based on the following general considerations: a. Ammonia is used to control pH. b. An oxygen scavenger is not needed if the oxygen concentration is below 10 ppb. If the use of an oxygen scavenger becomes necessary, hydrazine is preferable if allowed by local safety regulations. c. To minimize the risk of flow assisted corrosion in the lowpressure systems (see Appendix II), the pH range has a relatively high limit and the use of organic treatment chemicals is not recommended. Boiler water chemistry control is based on the following considerations: a. General and specific corrosion protection of the pressure parts surfaces in the event of contamination ingress. b. Achieving the required steam purity. There are several accepted methods for controlling boiler water chemistry. The majority of drum type boilers, however, still use some form of phosphate treatment (see appendix I). The particular phosphate treatment (phosphate concentration and corresponding pH) should be selected based on the following main cycle considerations:

It is understood that these are general guidelines and may need to be modified to meet plant specific requirements. Additional operational information, highlights, and criteria for selecting particular chemical controls are provided in Appendix I and III. A brief discussion on flow accelerated corrosion (FAC) is presented in Appendix II.

D. Boiler Water (HP, IP and LP) The tables below give the prime choice for HRSG drum boiler water treatment. In deviation to this specification, the following standards can also be adopted: - VGB guidelines R450L / 1988 - EPRI guidelines TR110051 - specifications of boiler suppliers approved by Alstom Note: These guidelines do not apply to the Low Pressure (LP) drum if used as a feedwater tank. In such a case, the feedwater guidelines are applicable to the LP boilerwater. Parameter
