Circulating fluidized bed reactors (CFBs) are very similar in operation to fluidized bed reactors. The difference between CFBs and fluidized bed reactors is that fluidized bed reactors utilize only a single heated reactor with cyclones for char separation. This char may be combusted to produce thermal energy or for another use.
