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. “We’ve 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.”

Dec 03, 2020 · But you sure could use a cyclone to clean fly ash. If i had to do it, i would do as i did before, the burn tunnel, as short as possible, entering the cyclone, so the flames are still burning in the cyclone. That would gibe turbulence, time,and by insulating the cyclone, temperature. And i would use a short double cone cyclone.
