TVA - How a Coal Plant Works

Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

What coal is used as major fuel in thermal power plant only?

Power plants generally use steam coal which is a grade between anthracite and bituminous. Coal is first milled to a fine powder, which increases the surface area and allows it to burn more quickly. In these pulverized coal combustion systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high temperature.
