Fluidized Bed Combustion FBC Boiler - boilersinfo.com

(FBC) Fluidized bed combustion is a combustion technology used to burn solid fuels in steam boilers. In Fluidized Bed Combustion Boiler technology When air or gas is passed through an inert bed of solid particles such as sand supported on a fine mesh or grid, the air initially will seek a path of least resistance and pass upward through the sand.

See Figure 12.9. BFBC Boiler Design Principles Bubbling bed boilers are short and stocky because. O The low heat release rates make the plan area large. O A residence time of 2.0-2.5 s makes the freeboard only 6 m, even for larger boilers. With nearly 60-70% of evaporation taking place in the bed coils, the boiler bank load is

Why to prefer Fluidized bed combustion boilers ?:-

Dec 24, 2018· The fluidized bed combustion (FBC) takes place at about 840°C to 950°C for coal. Since this temperature is much below the ash fusion temperature, melting of ash and associated problems are avoided. Main reasons for consideration of Fluidized bed combustion Boiler :-Liberty of fuel choice Normally fuel burns at 700 to 900 Deg C.

Fluidized Bed Boiler - an overview | ScienceDirect Topics

The circulating fluidized bed (CFB) boiler (see Figure 8) takes the principle of the bubbling bed one step further and with increased fluidization velocity the particles are lifted out of the bed and follow the gas out of the combustion chamber. They are then separated from the gas in a cyclone or beam separator and returned to the bed.
