commercial fuel combustion units commonly use multiple cyclones generally upstream of a wet scrubber, ESP, or fabric filter which collect fine PM 2.5 m with greater efficiency than a single cyclone. In some cases, collected fly ash is reinjected into the combus tion unit to improve PM control efficiency AWMA, 1992

Jun 26, 2018 Cyclones typically do not follow biomass boilers for fly ash removal. Boilers have fly ash, and that is challenging for cyclones, Clark says. Weve done it with a high-efficiency cyclone and a Venturi scrubber with high pressure drop. Typically what you see following a boiler is a multiclone followed by a wet ESP.
