Coal Pulverizers Power Plants

The coal input to the boiler of the power plant passes through three different phases before combustion in the boiler. Receiving, storing, and transporting the coal to the boiler. This is bulk storage and bulk handling. Preparing the coal for firing or pulverizing. This is what is special in a coal fired power plant, especially large thermal.
