Fluidized bed combustion boilers - energypurse.com

Atmospheric Fluidized bed combustion 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), as soon as it reaches bed combustion takes place. In bed tubes are used in AFBC boiler …
