Coal-fired Power Plants
In a coal-burning power plant, the burning of the coal produces heat which converts water into steam. The steam, at high pressure, flows from the boiler to the turbine-generator where the steam spins the turbine. The spinning turbine is connected to the generator which produces electricity.
