What Is Coal Power Plant and How Does it Work?

Sep 23, 2021How does 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 the water, and returned to the boiler to start the process over.
