Agglomeration in Stripper Ash cooler of CFBC- A case study The bottom ash of Circulating fluidized bed (CFB) boiler contains large amounts of physical heat. When low quality coals are used in these types of boilers, the … CFD Modeling of Stripper Ash Cooler of Circulatin…View More
The boiler is designed for fluidising velocities up to 4.5 m/s, generating high turbulence and resulting in good mixing of hot bed material with fuel and recirculated fly ash. The height of the bed is kept constant through removal of the produced bed ash as a function of …View More
Fluidized bed combustion (FBC) 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 (sand, limestone etc.) through which jets of air are blown …View More
Fine particles of partly burned coal, ash and bed material are carried along with the flue gases to the upper areas of the furnace and then into a cyclone. In the cyclone the heavier particles separate from the gas and falls to the hopper of the cyclone. This returns to the furnace for recirculation.View More

The circulating fluidized bed (CFB) is a fuel flexible combustion technology capable of burning a wide range of solid fuels while achieving lower emission of pollutants. Technological surveys show that up to 95% of pollutants can be absorbed before being emitted into the atmosphere.View More
Jan 26, 2018 · The flue gas from the furnace goes through a cyclone and is let out to the atmosphere. In case of CFBC, Circulating fluidised bed combustion, the furnace is pressurised and the furnace gas is recirculated to capture the unburnt carbon, to increase the thermal efficiency of the boiler. Hence this is an improved version of FBC.View More
3-12 · water cooled ash cooling screw, rolling-cylinder ash cooler (RAC), fluidized bed ash cooler and high-strength steel belt ash cooler. The RAC and FBAC have a large capacity, and have been commonly and reasonably applied in boilers. In CFBC boiler the ash generated due to combustion of coal is collected in major four areas.View More
“ (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.View More
