  • CoalFired Thermal Power Plant sciencedirect

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