Esa Kari Vakkilainen, in Steam Generation from Biomass, 2017. 10.5.2 Cyclones. A CFB boiler typically has one or more high temperature cyclone-type solid separators. These cyclones can be built separately, Fig. 10.8, or integrated into the furnace.Small-diameter cyclones would have a higher collection efficiency, but costs favor building fewer and bigger cyclones.
