Circulating Fluidized Bed (CFB) Boilers | Boile

Circulating fluidized bed (CFB) boilers feature the fast fluid bed which is formed in the whole furnace (combustor), and particles are collected in a cyclone and recirculated into the furnace. Therefore higher combustion efficiency and furnace desulfurization/ denitrification efficiency than those of other types of fluidized bed boilers can be achieved.

How Circulating Fluidized Bed Boilers Wor

Fluidized Bed. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air supply is from under the bed at high pressure. This lifts the bed material and the coal particles and keeps it in suspension. The coal combustion takes place in this suspended condition. This is the Fluidized bed.

Fluidized bed combustion - Wikiped

Fluidized bed combustion is a combustion technology used to burn solid fuels. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials through which jets of air are blown to provide the oxygen required for combustion or gasification. The resultant fast and intimate mixing of gas and solids promotes rapid heat transfer and chemical reactions within the bed…
