Theory of Thermal Power Station. Usually, steam is produced from high-pressure boiler by utilizing heat generated from fossil fuel. In India, to run the thermal power plant, most commonly used coal is in form of bituminous or brown type, though less qualified peat one also utilized used. In the power plant water generally used in steam generator where steam is generated, flows thru the turbine (which drives an electrical
Dec 25, 2015 Boiler or more specifically steam boiler is an essential part of thermal power plant. Thermal power plant is usually referred as coal thermal power plant. Generally, bituminous coal, brown coal and peat are used as fuel of boiler in a coal power station. The coal is used as boiler fuel has volatile matter from 8 to 33 % and ash content 5 to 16 %.
The heat from combustion of the coal boils water in the boiler to produce steam. In a modern power plant, boilers produce steam at high pressures and temperatures. The steam is then piped to a turbine. The high-pressure steam impinges and expands across a number of sets of blades in the turbine. The impulse and the thrust created rotate the turbine.
