Flame Stability - an overview | ScienceDirect Topics

2010-5-4 · B. Miller, in Ultra-Supercritical Coal Power Plants, 2013 Volatile matter content. Volatile matter is one of the factors governing the ignition and flame stability, the reactivity and burnout of chars, and the amount of unburned carbon in the fly ash (Carpenter, 1998).It is also one of the factors determining the fineness of grind required, and hence puvlerizer capacity and burner settings.

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 []
