circulating fluidized bed - an overview ScienceDirect …

A circulating fluidized-bed (CFB) reactor is very similar to a bubbling fluidized-bed reactor. The major difference is the gas velocity. If the gas velocity of a bubbling fluidized bed increases, at some point the force exerted on the particle will be enough to move it upwards, carrying it outside of the bed. This situation is called elutriation.
