How a Coal Plant Works. Coalfired 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 water and returned to the boiler to start the process over. Here's a real ...

A thermal power station is a power plant in which the prime mover is steam driven. Water when heated turns into steam which drives a steam turbine. After passing through the turbine, the steam is condensed in a condenser and recycled to where it was heated. [Rankine cycle] Coal is used as a fuel to heat water in a coal based thermal power plant.
