A two-dimensional reactor model for circulating fluidized beds (CFB) was studied based on the assumption that at every location within the riser, a descending dense phase and a rising lean phase coexist. Fluid mechanical variables may be calculated from one measured radial solids flux profile (upward and downward).
J.M. Wheeldon, D. Thimsen, in Fluidized Bed Technologies for Near-Zero Emission Combustion and Gasification, 2013 13.1.3 Bubbling fluidized bed combustion. Bubbling fluidized bed technology was first used for gasification by Winkler in 1921 and work on bubbling fluidized bed combustion (BFBC) technology started in the 1950s, several years prior to that on CFBC.
Circulating Fluidized Bed (CFB) Boilers. A circulating fluidized bed (CFB) boiler features higher gas velocity (superficial flow velocity) in the furnace (combustor) compared with a bubbling fluidized bed (BFB) boiler. The boiler activates a mixture of particles and gas to improve combustion reaction. Moreover, the fluid sand and fuel issuing out of the furnace are collected in a cyclone and recirculated …
