Basic principle of thermal power plant 



 A generating station which converts heat energy of coal combustion into electrical energy is known as a steam power station. Steam is produced in the boiler by utilizing the heat of coal combustion. The steam is then expanded in the steam turbine and is condensed in a condenser to be fed into the boiler again. The steam turbine drives the alternator which converts mechanical energy of the turbine into electrical energy.

Coal Handling Plant Details 

Source of coal = Piparwar Mines North Karanpur (Jharkhand)



Location = Near Ranchi



Distance = 1200 Kms.



Type of coal=f-grade(Washed) E-grade(raw)



Coal requirement=13,000MT/Day(04 rakes)

Ash Handling Technique 





 A natural result from the burning of fossil fuels, particularly coal, is the emission of flyash. Ash is mineral matter present in the fuel. For a pulverized coal unit, 6080% of ash leaves with the flue gas. Two emission control devices for flyash are the fabric filters and electrostatic precipitators. Electrostatic precipitators have collection efficiency of 99%, but do not work well for flyash with a high electrical resistivity (as commonly results from combustion of lowsulfur coal). In addition, the designer must avoid allowing unburned gas to enter the electrostatic precipitator since the gas could be ignited.
