In a thermal power station, like the Queen
Elizabeth Power Station in Saskatoon, natural
gas is burned in a turbine, which drives a
generator to make electricity. The exhaust
gas is used in a boiler to convert water to
steam.
The high-pressure steam is directed into a
turbine, which turns a shaft. This shaft is
connected to a generator that makes power
as it turns.
A condenser converts the steam from the turbine
back to water. That water is reused in the
boiler.
