Circulating Fluidized-Bed Boilers - Babcock

Circulating Fluidized Bed (CFB) Boilers. A circulating fluidized bed (CFB) boiler features higher gas velocity (superficial flow velocity) in the furnace (combustor) compared with a bubbling fluidized bed (BFB) boiler. The boiler activates a mixture of particles and gas to improve combustion reaction. Moreover, the fluid sand and fuel issuing out of the furnace are collected in a cyclone and recirculated …

Mitsubishi Power, Ltd. | Circulating Fluidized Bed (CFB

In circulating fluidized bed combustion (CFBC) (Fig. 5), the gas velocity is higher than in FBC, and a large part of the solid particles is carried over from the bed into a tall riser, where the particles aggregate into clusters that reflux at the wall. Particles that are carried over from the riser are precipitated by a high-temperature process cyclone and are recirculated into the riser.

Feb 25, 2009 · The production of a hydrogen-rich gas from biomass can be established by the AER (absorption enhanced reforming) process. Based on the dual fluidized bed steam gasification process, it uses a bed material which, apart from its function as heat carrier, acts as a CO 2 transporting agent and selectively transfers CO 2 from the gasification reactor to the combustion reactor.

Lessons Learned from Ensuring Circulating Fluidized Boiler

A method for treating fly ash of flue gas exiting a furnace of a fluidized bed boiler. A side flow conveying a first fraction of fly ash is separated from a flow conveying a second fraction of fly ash. After the separation, the side flow conveying the first fraction has a higher solids content than the flow conveying the second fraction.
