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

A circulating fluidized bed (CFB) involves a scrubbing technology known as a dry scrubber process. In this process, hydrated lime, limestone, or dolomite and water are intimately mixed with flue gas in a dedicated reaction chamber, which is the fuel-firing bed. Reacted solids get dried completely by the sensible heat of the flue gas.

CIRCULATING FLUIDIZED BED REACTOR - Chemical …

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
