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.
