Bubbling Fluidized Bed Boiler - an overview

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

Fluidized Bed Boilers Video - Convergence Training

In a fluidized bed boiler, hot air is blown at a high velocity up through a bed of sand, limestone, and ash causing the solid particles to fluidize, or behave like a liquid. Fluidization provides good mixing and allows for effective combustion when fuel is added. Fluidized bed combustion (FBC) provides several advantages for burning solid fuels
