    Best Practices for the Design and Operation of Coal Mill

    Coal mill dust collectors have a substantial effect on productivity, yet have received relatively little attention as companies implement cost-saving programs, like the use of petcoke as a fuel reduction measure. Petcoke is typically ground finer than coal, and it has a particularly sticky nature that makes it more difficult to clean from filter bags. Its high sulfur content increases the

    Coal-mill optimisation in coal-fired power stations aids

    Coal mills play a critical part in the flexible operation or load following operation of PCF plants. Critical components which need to be controlled in coal supply operation are coal-feed rate, air-feed rate, and particle size. Many problems experienced with ramp rates and flexible operation of PCPP can be traced to coal mills, both the mill itself and the operation and control system.
