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

The CFB operates at higher fluidization velocity, lower mean bed particle size, and higher recirculation rate than conventional FBC systems. A 50 x 106 Btu/hr unit has been installed and is presently undergoing start-up at a Conoco plant in Uvalde, TX. several studies have tentatively concluded that capital costs for a CFB boiler would
