Feed Coal - an overview | ScienceDirect Topics

13.2.17 Loss of coal feeder. Loss of a coal feeder causes raw coal feed to associated puverizer to shut off. Since in a direct firing system, fuel is fired according to the requirement of the steam demand and reserve fuel in a pulverizer is very limited, a loss of feed will cause unbalance in operating pulverizer/s, thereby impairing the ...

thermal power plant processes coal mill

The power input to mill motors depends on the coal flow. In many power plants the coal flow is calibrated with the raw coal (RC) feeder speed, and a few plants have gravimetric feeders where the coal flow can be measured using load cells installed in the feeder. The gravimetric feeder gives a better coal measurement compared with the RC feeder .
