how circulating fluidized bed boilers work?

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
