How a Coal Plant Works - TVA

Sep 12, 2021 · How a Coal Plant Works. Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

Natural gas power plant - Energy Education

Natural gas power plants generate electricity by burning natural gas as their fuel.There are many types of natural gas power plants which all generate electricity, but serve different purposes. All natural gas plants use a gas turbine; natural gas is added, along with a stream of air, which combusts and expands through this turbine causing a generator to spin a magnet, making electricity.
