Bubbling fluidized beds: When to use this technology

Bubbling fluidized bed boilers (BFB) are often preferred in small-scale applications, with fuels having low heat value and high moisture content. Foster Wheeler (FW) has supplied more that 130 BFB boilers, mainly for industrial use. Boiler efficiency figures (over LHV) are normally over 90% (Figure 1). The core of the BFB boiler is the

Bubbling Fluidized Bed - an overview | ScienceDirect Topics

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.

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 zone ( Fig. 5.3 ).
