Fluidized Bed Combustors for Biomass Boilers - AS
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.

EcoFluid bubbling fluidized bed boilers - ANDRI
ANDRITZ EcoFluid boilers are based on Bubbling Fluidized Bed (BFB) technology for producing steam and electricity from solid fuels such as renewable biomass and alternate fuels such as sludge, Refuse-Derived Fuel (RDF) and residues. EcoFluid boilers employ proven, yet modern combustion technology to efficiently produce power while keeping emissions within environmentally safe limits.

Fluidized Bed Combustion | Fluidized Bed Boiler |F
The heat released during combustion heats up the surrounding boiler tubes and generates steam. The major advantages of Bubbling Fluidized Bed Combustion are the enhanced thermal efficiency, easy ash removal. Another type is the Circulating Fluidized Bed Combustion; it is applied to fuels with higher heating values such as Petcoke.
