Fluidized bed combustion - Wikipedia

2019-9-30 · 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 to provide the oxygen required for combustion or gasification.

Atmospheric Fluidized bed boilers are most common and simple FBC boiler where combustion takes place at layer of sand or sand like material. Bubbling of sand bed is created with the help of fluidizing air of velocity 1.2-3.7 m/sec. Coal of size 0-10mmis spread over bed (typically 1-6 mm size for under bed firing and 6-10mm for overbed firing
