Most U.S. and world electricity generation is from electric power plants that use a turbine to drive electricity generators. In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins (rotates) the rotor shaft of a generator.

The diagram illustrates the process of generating electricity from coal. In the first stage, coal is sent to a pulveriser through a conveyor belt where it is crushed until it becomes a fine powder. Milled coal is then blown into the combustion chamber of a boiler and is burnt at high temperature. The burning coal produces hot gases and heat ...

Steam coal, also known as thermal coal, is used in power stations to generate electricity. First coal is milled to a fine powder, which increases the surface area and allows it to burn more quickly. In pulverised coal combustion (PCC) systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high temperature.
