Fluidized Bed Combustion | Fluidized Bed Boiler |FBC

Principles of Fluidized Bed Combustion Operation: A fluidized bed is composed of fuel (coal, coke, biomass, etc.,) and bed material (ash, sand, and/or sorbent) contained within an atmospheric or pressurized vessel. The bed becomes. fluidized when air or other gas flows upward at a velocity sufficient to expand the bed.
