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.
