Coalmill Optimisation In Coalfired Power Stations Aids

Jan 23, 2018 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
