Fluidized bed combustion - Wikipedia

2019-7-23·Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.

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.
