Coal Ash Processing - PEC Consulting Group
2021-11-16 Fly Ash – a very fine, powdery material composed mostly of silica resulting from the combustion of finely ground coal in a boiler and being drafted by the off-gases into a dust collector. Bottom Ash – a coarse, angular ash particle that is too large to be carried up into the off-gases, so it drops to the bottom of the coal furnace.
