Coal & electricity
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.
