Why to prefer Fluidized bed combustion boilers ?:

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

Fluidised Bed Combustion System (FBCS): Working

1. Introduction. to FBC System: (a) Oil and gas prices increased in recent decades. (b) Coal is available in large quantities. (c) Pulverized coal burning system is costly and the combustion takes place at 1400-1600°C at which NO x is produced. (d) At high temperature, ash forms a slag on super heater tubes and causes fouling, corrosion and reduces heat transfer rates.
