Coal-mill optimisation in coal-fired power stations

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 []
