fINTRODUCTION. A thermal power station is a power plant in which the. prime mover is steam driven. Water is heated, turns. into steam and spins a steam turbine which drives an. electrical generator. After it passes through the turbine, the steam is. condensed in a condenser and recycled to where it was.
