Coal-fired power plants generate electricity by burning coal in a boiler to produce steam. The generated steam flows into the turbine under enormous pressure, driving the generator to generate electricity. The steam is then cooled, condensed and returned to the water, then returned to the boiler, and the process restarted from the beginning.
