The combustion and slagging characteristics of three brown coals and their blends have been studied on the combustion research facility (CRF) in order to obtain the relationship between the blends and their parent coals which are all used in the SL Power Plant in China . Coal H is the designed coal for the boilers of the SL Power Plant but it is usually blended with coal Y and M. The experimental results show that when two coals are blended and then burnt, these two coals still keep their own combustion characteristics, but the slagging characteristics of the coal blends differ significantly from their parent coals.
