The circulating fluidized bed (CFB) uses high fluid velocity to provide better gas-solid contact by providing more intense mixing of the fluid so that better quality of product can be obtained. However, the high gas velocities and the recirculation of solids may make the CFB system much more expensive in term of power requirement and investment compared to conventional fluidized bed reactors.

Heat transfer in a large-scale circulating fluidized bed boiler | …

A fluidized-bed working slightly above the minimum fluidization velocity is called a stationary fluidized bed or BFB. In these burners, the air flowing inside the bed forms bubbles that are dragged by the flow of air and create typical movements causing rupturing of the bed surface as they reach the top layer, which resembles a bubbling fluid, and a free-board zone above the fluidized bed.
