For typical coal powder boiler applications, the coal feeder is usually mounted under the bunker to continuously deliver the specified coal flow into the pressurized mill. The coal feeder is connected to the bunker via an inlet chute to allow positive coal loading on the belt of the coal feeder.
This is all controlled by the coal mill or pulveriser, and its associated feeder equipment. Operation of the coal mill can affect the ramp rate of the power station and its ability to handle rapid changes in output. For coal-fired power plants, the response time of the coal mills is critical for the overall reaction time to changing demand.
