    In an inflated fuel firing system, coal is reduced to a fine powder with the help of grinding the mill and is then projected into the combustion chamber with the help of hot air current. The amount of air required (secondary air) to complete the combustion is supplied separately to the combustion chamber.

    The wet coal is fed into a pulverizer along with hot gases drawn from the firing hood. The hot gas temperature is controlled by bleed air. The coal or coke is simultaneously dried and ground in the hot-air swept pulverizer. The pulverizer can be a hammer mill, ring-roll mill, or a ball mill type.

    Depending on speed pulverizers are classified as low-speed, medium-speed, and high-speed mills. Pulverized coal burners may be located on the front or opposed walls or in the corners of the furnace. There are two types of fuel-firing systems: bin system and direct-firing system. Coal feeders are either the volumetric or gravimetric type.
