Circulating Fluidized Bed - an overview | ScienceDirect Topi

In the circulating fluidized bed reactor, the gasifying agent is introduced upward at a velocity fast enough (3.5–5.5 m/s) to move the bed material throughout a circulating loop, full mixing and long residence times being achieved (see Fig. 15.8). Biomass is fed from the side and mixed with the hot bed material which is dispersed along the

Circulating Fluidized-Bed (IR-CFB) Boilers - Babcock & Wilc

Drawing upon our extensive technical expertise and operating experience, B&W developed the Internal Recirculation Circulating Fluidized-Bed (IR-CFB) boiler which is the technology of choice for power plant owners seeking economy, reliability and flexibility. In addition, load-following capabilities are attainable with B&W’s in-bed heat exchanger technology.

Fluidized Bed Combustors for Biomass Boilers - AS

Fluidized-bed boilers are the most common type of boilers recommended for biomass fuel. The fuel is suspended by an upward flow of combustion air through a bed of hot, inert particles, allowing oxygen to reach the combustible material more readily.
