Fluidized Bed Combustion - Assignment Poi

A fluidized bed may be defined as the bed of solid particles behaving like a fluid. Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels. It is a process in which solid particles are made to exhibit fluid-like properties by suspending these particles in an upwardly flowing evenly distributed fluid stream.

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 ( Fig. 5.3 ).

The bubbling fluidized-bed (BFB) gasifier is shown in Figure 9.4 in which the gasification agent is injected from the gasifier bottom and the producer gas exits from the gasifier top while the solid fuel is introduced to the bed. This type of gasifier is characterized by the bubbling of bed material and solid fuel by flowing gas through it when the gas velocity is sufficiently high.

Fluidized Bed Combustors for Biomass Boilers - AS

Boiler engineers can choose between two main types of fluidized-bed boilers—bubbling fluidized bed (BFB) and circulating fluidized bed (CFB). In BFB boilers the velocity of the combustion air is low enough that the fluidized particles remain in the lower furnace; in a CFB unit the velocity is greater and hot particles are circulated through the entire range of the boiler combustion zone.
