    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. The
