Fly ash “flies” or rises from burning coal and is generally collected in the burner/furnace’s emissions controls, filter, or scrubber. Coal Analysis can determine the make-up and mineral content of fly ash to determine if it meets preferred amounts to be used for composite, cement, bricks, or plasters.
