No other alternative site identified/considered as selected site found techno-economically and environmentally feasible for development of proposed project. 3.4 Size or magnitude of operation The proposed biomass based thermal power plant has capacity of 18 MW based on 100% paddy straw. The proposed project cover 106553.73 Sq.M (26.33Acres) of land & the project cost is 141.25 Crore. 3.5Project description with process details (a schematic diagram/ flow chart showing the project layout, components of the project etc. Should be given). Power generation process is based on combustion technology with Rankine Steam cycle. For Power generation in thermal power plant is achieved by steam generation at high temperature and pressure which is then used to run a turbine to generate electricity. Paddy straw will used as fuel for steam generation. Steam generation requires heating demineralized water in the boiler at high temperature and pressure. Steam at high temperature 540 ̊ C and high pressure (95 Kg/cm 2) is fed to rotate the turbine to generate power. Spent steam is converted into condensate by cooling in heat exchanger. Cooling water used in heat exchanger is cooled in the cooling tower. Paddy Straw for generation of 1 Kw-Hr Power, the same has been estimated at 1.20 kg. This has been based on Boiler efficiency of 75%, Station Heat Rate of 2313.25 Kcal/Kw-Hr requirement of Steam for generation of 1 Mw-Hr of Power has been estimated at 3.805 TPH. Thus for generating 18 MW Power, total hourly requirement of Steam comes to 3.805 x 18 =68.49 TPH. As against this, MCR of Boiler is 80 TPH. The detail description of process is attached in Annexure 1.

TECHNOLOGY SELECTION

Bio-mass

5.1

Bio-mass is the agricultural residue coming out after the main crop is cultivated or processed. Bio-mass comprising of several agricultural residues and woods has emerged as an non-conventional source of energy in the country.

5.2

Bio-mass has always been an important energy source for the country considering the benefits it offers. Bio-mass is renewable, widely available, Carbon neutral and has the potential to provide significant employment in the rural area. Bio-mass is also capable of providing firm energy. Further, Biomass is a clean fuel & environmentally benign as compared to conventional fuel.

5.3

Basically there are 2 technologies available for producing electrical energy from Bio-mass. These are : (i) (ii)

Combustion Technology using Rankine Cycle Gasification Process using Auto Cycle Combustion Technology

5.4

In Combustion Technology, Bio-mass is burnt in a Boiler to produce steam. This is the most commonly used technology for producing power from Bio-mass. The advantage is that the technology use is similarly to that of a thermal plant base on fossil fuel like Coal, except for the Boiler. The Cycle used is conventional Rankine Cycle with Bio-mass being burnt in high pressure Boiler to generate steam and operate a Turbine with generated steam to produce electricity.

5.5

In Combustion technology with Biomass, primarily 2 types of Boilers are used viz Grate Boiler & Atmospheric Fludised Bed Combustion (AFBC) Boiler. The selection of Boiler depends on type of Bio-mass used for firing the Boiler. Gasification Process

5.6

Under gasification process, Bio-gas consisting about 52% Methane is generated through Fermentation of Bio & Agro Residue/waste in a Digester and burning the gas generated in a Gas engine coupled with an A.C. Generator to produce Electricity. The process is called Auto Cycle.

U.B. CONSULTANTS PRIVATE LIMITED PROJECT & MANAGEMENT CONSULTANTS

Sukhbir Agro Energy Limited TEV Study for 18 MW Biomass Project (Rice Straw Based) at Faridkot

88

5.7

Process for generation of Electricity from Bio-Gas in an Auto Cycle Plant is summarised below :

5.7.1

To generate Electricity from Bio-gas , the steps that must be gone through are twofold, chemical energy to mechanical energy and then from mechanical energy to electrical energy.

5.7.2

For these conversion processes to be achieved, a suitable Engine which shall be used for the generation of electricity from bio-gas digester is required.

5.7.3

The Bio-gas produced from the digester is slightly above the atmospheric pressure and needs to be compressed to approximately 150 m bar in a radial gas compressor to feed to the engine.

5.7.4

A gas engine is similar to an automobile car engine. It is an internal combustion engine which will burn the methane to convert the chemical bond energy of the gas to heat energy expanding the gases within the piston, driving the drive shaft and producing mechanical energy.

5.7.5

The mechanical energy in the rotating drive shaft is then coupled into an electrical generator.

5.7.6

The mechanical energy is utilized to drive the AC (alternating current) generator giving electricity. Of course, the generator also has to be connected into an electrical power distribution grid, and to save on power loss during transmission through the cables the voltage is raised in a step-up transformer.

5.7.7

A Combined Heat and Power (CHP) system is always worth considering. The idea of CHP is that, it uses the hot water otherwise wasted when the excess heat is cooled before it can go back into the circuit.

5.8

Auto Cycle Plants did not gain popularity in the country. Also Cost / MW of Auto Cycle Plant is higher as compared to Rankine Cycle Plant. Further as Auto Cycle Plant did not gain popularity in India, for setting up of Auto Cycle Plant foreign collaboration / assistance is required. Technology Selected

5.9

As Combustion Technology is a standard technology in the country for producing Power from Bio-mass, SAEL proposes to adept Combustion Technology within Rankine Cycle process. Further, the Company is having considerable experience in operation of 2 Nos. Bio-mass Power Plant of capacity same as that which SAEL proposes to install, selection of Combustion Technology is considered to be appropriate. U.B. CONSULTANTS PRIVATE LIMITED PROJECT & MANAGEMENT CONSULTANTS

Sukhbir Agro Energy Limited TEV Study for 18 MW Biomass Project (Rice Straw Based) at Faridkot

89

5.10

However, while utilizing Combustion Technology, selection of Boiler assumes importance. Selection of Boiler depends on the major Bio-mass to be used in the Plant for firing. For the subject Plant, Boiler is propose to be fired with 100% Paddy Straw.

5.11

SAEL, in consultation with major Boiler manufacturing company i.e. DP Clean Tech, Shanghai Power Equipment Research Institute Co. Ltd, BWSC has decided to install one number Single Drum, natural Circulation, Balanced Draft , Water Tube Biomass fired. Travelling Grate, Spreader Stoker Boiler suitable for steam output capacity of 80 tons per hour at 95 Kg/ cm2 (g) pressure and steam temperature of 540 0C, all measured at Superheater outlet at boiler MCR (Maximum Continuous Rating).

5.12

SAEL will decide on vendor for supply of Travelling Grate Boiler capable of accepting 100% Paddy Straw firing in due course. For that purpose SAEL is negotiating with reputed vendors like, DP Clean Tech, Shanghai Power Equipment Research Institute Co. Ltd, BWSC etc.  Advantages of Travelling Grate Stoker

5.13

Advantages of Travelling Grate Stoker are given below: 

Insensitive to fuel size.



Fuel containing maximum moisture can be successfully burnt.



Rapid load swings can be accommodated due to large inventory of the fuel on the grate.



Simple control.



Robust construction with minimum maintenance, hence high operating reliability.



Simple and rapid installation.



Low power consumption.



Efficient fuel feeding system using hydraulically actuated feed piston and divergent hoppers

Boiler Plant Design

5.14 The steam boiler is designed for firing various types of straws mainly paddy straw. The boiler plant design is based on Boiler Manufacturer’s experience with biomass fuels. 5.15 The fuel is introduced in the furnace through water cooled stoker ducts. The size of the combustion grate and the size and geometry of the combustion chamber, with respective combustion air nozzles, is designed with the aim of ensuring the complete combustion of the biomass fuel. 5.16 The boiler and the combustion grate are based on the bottom support design, simplifying the design of the sealing between the vibration grate and the boiler walls. The flue gas outlet of the boiler is connected to a separate tower with economizer and air preheater. 5.17 The combustion air is preheated in order to provide a more stable combustion process and to improve the overall boiler efficiency. 5.18 The spacing (pitch) between the heat surface tubes in the hanging super heater in the first pass is adapted to allow for the formation of deposits (scaling) known to form on the tubes due to the relatively low melting temperature of straw ash. The design and materials are specifically selected to counteract the high temperature corrosion related to straw firing. 5.19 All connections in the steam boiler will be fully welded. No tubes will be pressure expanded. 5.20 The boiler convection pass, economizer are cleaned with steam soot blowers. Combustion process

5.21 The combustion process involves a number of physical / chemical aspects of high complexity. The nature of the combustion process depends both on the fuel properties and the combustion applications. However, it can be separated into four different phases (drying, pyrolysis, gasification and combustion). In large scale applications, with continuous fuel feeding, these processes will occur in different sections of the grate.

91

Straw Feeding System

5.22 The straw feeding system has the following functions: 5.22.1 It shall loosen the straw from the compressed layers of the straw bales and allow the formation of a uniform straw feed, filling out the stoker ducts and proceeding into the boiler combustion zone. 5.22.2 It shall ensure a constant feeding of the straw corresponding to the desired boiler load irrespective of the compression of the straw bales. 5.22.3 It shall ensure that any risk of fire from the furnace back into the straw lines is contained. 5.22.4 From the scarifier screws, the separated straw falls down into the stoker screws, which push the straw into the stoker ducts and into the furnace. The stoker ducts are watercooled not only to withstand the heat of the furnace but also to limit the heat transported back to the straw feed system when the straw line is stopped. 5.22.5 To minimize any fire hazard, the straw feeding system includes a number of separate fire protection barriers: 5.22.6 Any operating straw line will operate at a minimum speed to avoid risk of backfires during normal operation. 5.22.7 A water-cooled damper is installed at the inlet of each stoker duct which, when the straw feed is stopped, will compress the straw in the duct. This measure will reduce the speed with which any potential backfire that may spread. 5.22.8 Also, when a straw feed line is stopped, water nozzles in the duct and at the inlet of the stoker screws will soak the straw. These systems are normally fully sufficient to avoid any spreading of fire. 5.22.9 The chute from the scarifier screw to the stoker screws is provided with a fire damper, which closes when a straw line is stopped. Furthermore, the area is provided with water nozzles connected to the plant firewater system, which will open if high temperatures are detected. 5.22.10 The straw lines to the scarifier screws are internally protected by a sprinkling system connected to the plant firewater system. 5.22.11 The feeding lines and scarifiers shall be indoor. 5.22.12 From the straw bale scarifiers, the straw enters the stoker screws, where a set of double screws pushes the straw into the water cooled stoker duct and into the furnace. The stoker ducts are provided with compression plates (“dynamic dollies”) which ensure that the stoker ducts are filled with straw in a uniform compression. U.B.

Slag and Ash System Sl ag Hopper af t er Gr at e

5.23 At the lower end of the grate the slag and bottom ash from the combustion will be collected in a hopper and dropped to the Wet submerged slag conveyor. The hopper will be provided with refractory, protecting it from the radiation of the furnace. An inspection and cleaning door will be built into the hopper. Submerged Slag Conveyor

5.24

At the lower end of the grate the slag and bottom ash from the combustion will be collected in a hopper and dropped to the Wet submerged slag conveyor. The hopper will be provided with refractory, protecting it from the radiation of the furnace. An inspection and cleaning door will be built into the hopper.

5.25

The conveyor extracts the slag from the water bath and delivers it to the pit.

5.26

The conveyor belt is tightened at the drive shaft. This adjustment is made by loosening the locking device and manually adjusting the tightening screws.

5.27

The scrapers of the slag conveyor are provided with zinc anodes to limit corrosion.

5.28

Due to water evaporation caused by the hot slag, there will be a constant need for refilling the conveyor system with water. The water control is carried out by a fully automatic control system mounted on the slag conveyor. Transport of Slag after Submerged Conveyor

5.29

The slag is transported by a conveyor belt to a pit at end of slag conveyor.

5.30

A pit for collecting water from the slag conveyor, as well as for draining the intermediate storage area for the slag is recommended. The water collected in this pit may be used for refilling the slag conveyor, reducing the required amount of separately added water. Heating surface cleaning systems

5.31

The steam boiler is equipped with a heating surface cleaning system. This system consists of steam soot blowers for superheaters the economizer and the air preheater. U.B. CONSULTANTS PRIVATE LIMITED PROJECT & MANAGEMENT CONSULTANTS

Sukhbir Agro Energy Limited TEV Study for 18 MW Biomass Project (Rice Straw Based) at Faridkot

93

5.32

The soot blowers located in the areas with high flue gas temperature will be of the fully retractable type. The soot blowers in the economizer and air preheater area will be semi- retractable. During operation, the soot blowers will rotate and move in the longitudinal direction, making the steam from the nozzles on the soot blower intercept the heat surfaces cleaning them.

5.33

Soot blowing sequences are anticipated to occur three times per day, or one sequence for each operator shift. The soot blowing steam is taken from the turbine’s first extraction, with a pressure of approximately 25 bar(a).

5.34

A local PLC for control of the different steam soot blowers according to the selected cleaning program is included. The start of the desired soot blowing program will be initiated from the central control system. Boiler Specification
