Coal-Fired Thermal Power Plant an overview

Coal is the dominating fuel source used in thermal power plants for generation of electricity. At the coal-fired thermal power plants, the raw coal is first pulverized to the shape of flour before it is force-fed to the furnace. During the pulverization process, the clay particles entrapped in the cracks of coal get separated from the coal.
