CFB uses coal crushed to sizes of around 3 to 6 mm. The time energy and facility required to crush coal is much lesser than pulverizing coal. PC firing uses around 30 % of the combustion air as high pressure primary air for drying and transporting fuel. CFB uses higher pressure primary air which is 60 % of the combustion air for fluidizing.

How Circulating Fluidized Bed Boilers Work? - Bright Hub

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 (CFB Series) Combustion technology utilizes the fluidized bed principle in which crushed fuel is injected into the furnace or combustor and the fine combusted particles are elutriated out of the furnace with flue gas. The balance particles are then collected by solid separators and circulated back into the furnace.
