Bubbling Fluidized and Circulating Fluidized Bed Boiler

The BFB boiler is the first-generation fluidized bed (FB) boiler. The furnace includes a dense-phase zone (also referred to as the bubbling bed) and suspension zone. The BFB boiler is typically used as an industrial boiler with 4∼35 t/h capacity. Its structural characteristics involve heating surfaces with immersed tubes in the dense-phase zone (

Principles of Fluidized Bed Combustion Operation

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.

Fluidized bed combustion - Wikipedia

Two types of fluidized-bed reactors can be distinguished: a bubbling fluidized bed and a fast fluidized bed, frequently also called circulating fluidized bed. Bubbling FBGs are characterized by moderate fluidization velocities and the fluid mechanic behavior is dominated by gas bubbles ascending in the fluidized bed.

The fluidized bed boiler is gaining in popularity and has overtaken the grate-fired boiler in biofuel power generation applications. The principle is very simple: air is blown through a bed of sand and fuel particles at a velocity that is sufficient to suspend the particles on the airstream but not able to lift them permanently out of the bed, that is, 1–3 m s −1 at 800–900 °C.
