How Circulating Fluidized Bed Boilers Work?

Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources. All this without compromising efficiency and with reduced emissions. This article gives a brief description of the working of a CFB boiler. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air

Circulating Fluidized Bed - an overview | ScienceDirect …

A circulating fluidized bed (CFB) is a fluidized bed system that includes a riser and a down-comer with the solid particles circulating between them. The riser is operated in a fast fluidization regime, with solids carried over from top and returned to bottom of the riser via a standpipe and feeding or control device. The operating variables

Circulating Fluidized Bed Technology | ScienceDirect

A feature of circulating fluidized bed combustors is that they can be operated at significantly lower temperatures than conventional (bubbling) bed units at the same level of combustion efficiency. An explanation of this phenomenon is provided in terms of increased superficial gas velocities and high particulate loadings in the freeboard.

A circulating fluidized-bed (CFB) reactor is extremely the same as a bubbling fluidized-bed reactor. the main distinction is that the gas rate.If the gas rate of a bubbling fluidized bed will increase, at some Location the force exerted on the particle are enough to move it upwards, carrying it outside of the bed. this case is named elutriation. In a CFB, elutriation carries each sand and char
