The fluid mechanical behaviour of different types of circulating fluidized beds can be explained with the aid of the state and pressure drop diagram for segregated vertical gas‐solids flow. As an example, the operating behaviour of circulating fluidized bed with a syphon in the solids downcomer is discussed.

Fluidized Bed Boiler - an overview | ScienceDirect Topics

In fluidized-bed boilers a bed, usually consisting of sand particles, is brought into a fluidized state by primary air supplied from below the bed. Solid fuel added to the bed will burn in the oxygen-rich conditions inside the bed created by the primary air.

Fluidized bed combustion - Wikipedia

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.

04-12-2016 · In early 1960s, Douglas Elliott [ 4 ] promoted bubbling fluidized bed using the idea of burning instead of gasifying fuel and focused on the advantages of burning coal in fluidized beds by immersing boiler tubes in it. Lurgi [ 5 ] developed an aluminum calcining process based on laboratory-scale work in their Metallgesellschaft laboratories.
