Fluidized Bed Furnace - an overview | ScienceDirect Topics

In the CFB combustion process the fluidization velocity is increased past the bubbling regime to the transport regime (Basu 2006)High velocity causes a large fraction of the sand and ash to become entrained with the flue gas stream (Monazam and Shadle 2004)The furnace acts as the riser of a fast (Basu and Fraser 1991)One needs some type of solid separator after the furnace
