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 ...Jan 01, 2014 Development. The project included the replacement of the old raw coal feeding equipment to the mill, which consisted of an apron feeder, for the new design of rotor weighfeeder Pfister TRW-K.

2.Coal pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transport to the boiler burner ...Power plant boiler fuel demand is transmitted as a coal feeder speed demand to a coal pulverizer control. A speed controller operates the feeder in accordance with the speed demand, and a position controller for a hot coal transport air damper positions the hot air damper to hold the mill outlet temperature to a setpoint value and to increase or decrease damper position in accordance with a ...

The coal interruption fault is often caused by the blockage of coal bunker or the coal feeder failure. When the coal interruption occurs, the coal feed flow into the mill will suddenly reduce to 0. Therefore, it is only to step down the signal of coal feed flow to 0 to realize the simulation of coal interruption.The Gravimetric Feeder compensates for the variation in bulk density by feeding a fixed weight of coal in response to a boiler demand. This ability to accurately weigh the coal on an “as-fired” basis provides significant improvement over volumetric feeders in terms of matching the BTU delivered by the feeder …
