Coal fired power plant - Energy Education

The pulverized coal is then input to a boiler, where combustion occurs and the coal provides heat to the power plant. This heat is transferred to pipes containing high pressured water, which boils to steam. The steam then travels through a turbine, causing it to rotate extremely fast which in turn spins a generator, producing electricity.
