General Description of Thermal Power Plants


Globally power stations utilize various sources of energy such as fossil fuels, nuclear, hydroelectric, solar, wind, and wave. A thermal power plant utilizes the “heat of combustion” of fossil fuels. A steam power plant constitutes a steam generator, a steam turbine, generator, condenser, heaters, pumps, fans, and other auxiliaries. Rankine cycle is the backbone of steam power plants. A gas turbine power plant comprises an upstream compressor coupled to a downstream turbine, and a combustion chamber in-between; and also a generator. Principle of operation of a gas turbine is based on the Brayton cycle or the Joule cycle. A Diesel generating station uses a Diesel engine and a generator ...
