How Circulating Fluidized Bed Boilers Work?
Circulating fluidized bed combustors (or boilers) are one of the most widely used gas-solid convertors around the globe. As it plays an essential role in boiler design, different researchers have suggested different operating regimes for CFB combustors, based on their findings from experiments or practical experiences.
CIRCULATING FLUIDIZED BED REACTOR Chemical Engineering World
Circulating fluidized bed (CFB) boilers use all kinds of solid fuels, from biomass to refuse derived fuel (RDF), to produce reliable and efficient clean energy. Fuel flexibility is at the core of CFB technology, contributing to fossil fuel and CO 2 emissions reduction while using local alternative renewable fuels.
Fluidized Bed Combustion Boilers (FBCB)
Circulation Fine particles of partly burned coal, ash and bed material are carried along with the flue gases to the upper areas of the furnace and then into a cyclone. In the cyclone the heavier particles separate from the gas and falls to the hopper of the cyclone. This returns to the furnace for recirculation.

ANDRITZ PowerFluid boilers are based on Circulating Fluidized Bed (CFB) technology to produce steam and electricity from nearly all solid fuels from biomass to alternative fuels and wastes. PowerFluid boilers employ proven, yet modern combustion technology to efficiently produce power while keeping emissions within environmentally safe limits.
Circulating Fluidized Bed CFB Boiler Process YouTube
Fluidized-bed boilers are the most common type of boiler recommended for biomass fuel, which is burned within a hot bed of inert particles, typically sand. The fuel-particle mix is suspended by an upward flow of combustion air within the bed. As velocities increase the gas/solid mix exhibits fluid-like properties.

Designed to stand the harshest conditions, CFB boilers can better resist tube corrosion, wear, and ash adhesion, making high-temperature, high-pressure steam conditions possible for all fuels. For large-scale plants, ultra-supercritical steam at 257 bar and 603°C is available. Fuel-flexibility is critical for new plants to maximize inexpensive.
