Thermal power station

A thermal power station is a power station in which heat energy is converted to electric power. In most of the places in the world 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; this is known as a Rankine cycle. The
