  • How Coal Power Plant Works? - Do You Know? -

    The coal so arrived by the conveyor cannot be used the way it is, it is first converted into powder form also known as pulverized coal. It is made to rotate in a cylindrical tank at high speed with lots of spherical steel balls and thus converted into powder. Pulverizing plant also has the storage for un-pulverized coal and can store upto 30 hours of coal feed.
