Circulating fluidized bed - Wikipedia

The circulating fluidized bed (CFB) is a type of Fluidized bed combustion that utilizes a recirculating loop for even greater efficiency of combustion.[1] while achieving lower emission of pollutants. Reports suggest that up to 95% of pollutants[2] can be absorbed before being emitted into the atmosphere. The technology is limited in scale
