Thermal power station - Wikipedia

A thermal power station is a power station in which heat energy is converted to electric power. In most places the turbine 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 heated.
