Thermal power station - Wikipedia

A thermal power station is a power station in which heat energy is converted to electricity.Typically, fuel is used to boil water in a large pressure vessel to produce high-pressure steam, which drives a steam turbine connected to an electrical generator.The low-pressure exhaust from the turbine passes through a steam condenser and is recycled to where it was heated.
