    Coal-mill optimisation in coal-fired power . - EE Publishers

    Many of the existing pulverised coal-fired (PCF) power stations are operated at a fixed steady load (i.e. baseload operation). There is however a growing requirement for load following or flexible operation, which requires flexibility in most of the components of the power station. Flexibility and efficiency can be improved by close control of the coal [.]

    Effects of Mill Performance on Unburnt Carbon in Coal .

    Pulverized coal were sampled isokinetically from the PC pipes. The results indicate that there is a significant mal-distribution of coal mass flow in the PC pipes. The particulate size was also coarse. As a result, the heat release from the combustion of coal occurred higher up in the boiler, leading to a flue gas exit temperature.
