A thermal power plant is one kind of plant or system, which is used to produce electrical power by using thermal energy. Fig. 1 Thermal power plant. Coal is mainly used as fuel. Normally brown, bituminous, and peat coals are widely used. Water is used as secondary fuel which helps to transfer thermal energy from coal.

Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into the water, and returned to the boiler to start the process over.
