How a thermal power station works
In a thermal power station, fuel (coal or natural gas) is burned in a boiler to convert water to steam.
The high-pressure steam is directed into a turbine, which turns the turbine shaft. This shaft, connected to an electrical generator, produces electricity as it turns.
A condenser converts the spent steam from the turbine back to water that
is reused in the boiler. The condenser cooling water comes from the reservoir
and is returned for reuse.
