    Why Pulverized Coal is Used in a Power Plant 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

    Pulverizers have three functions, pulverization, drying and classification. The classification function plays the important role of ensuring that only fine particles of the pulverized coal are sent to the boiler. Within a rotating-type classifier, fine particles are passed through while coarse particles are eliminated by utilizing the relative balance of centrifugal force and centripetal

    Combustion tuning of a pulverized coal boiler begins with balancing the air and fuel flows in the coal pipes from the pulverizers to the burners. Note that each of the coal pipes is a different length. On most boilers, burners are also present on the opposite side of the furnace, adding to the air/fuel-balancing challenges. Courtesy:

    Aug 13, 2009 Pulverized coal is the most efficient way of using coal in a steam generator. The coal is ground so that about 70 % will pass through 200 mesh (0.075 mm) and 99 % will pass through 50 mesh (0.300 mm). A pulverized coal boiler can be easily adapted for other fuels like gas if required later without much difficulty
