Coal feeders provide coal to the coal pulverizers (mills) where the coal is pulverized and dried. Dryer coal is easier to pulverize, and less mill power is needed to achieve the same coal fineness. Additionally, with less fuel moisture, more complete drying of coal can be achieved in the mill. This results in increased mill exit temperature (the temperature of the coal and primary air mixture at mill exit), better conveying of .

In this system, the raw coal from the coal bunker drops on to the feeder. Hot air is passed through coal in the factor to dry the coal. The coal is then transferred to the pulverising mill where it is pulverised. Primary air is supplied to the mill, by the fan. The mixture of pulverised coal and primary air then flows to burner where secondary air is added.

Until the late 1960s, the company's major specialty was feeding, measuring, and controlling the flow of coal from the coal bunker to pulverizers or stokers. As demand for electricity increased in the 1950s and 1960s and concern about pollution grew, the firm developed a gravimetric feeder to permit accurate control of combustion in the boiler and minimize stack emissions.
Jun 03, 2015· To prevent the backward flow of hot gas from a downstream pulverizer or boiler feed system at a power plant, cool inert gas is added to the feeder housing. To be effective, this sealing gas must be at a slightly higher pressure than the downstream system.
