Fluidized Bed Combustors for Biomass Boilers - ASME

2012/8/30 · Fluidized-bed boilers are the most common type of boiler recommended for biomass fuel, which is burned within a hot bed of inert particles, typically sand. The fuel-particle mix is suspended by an upward flow of combustion air within the bed. As velocities increase the …

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

5.2.2 Fluidized-bed combustion. Fluidized-bed combustion (FBC) uses a mixture of particles suspended in an upward flowing airstream, which combine to exhibit fluid-like properties. Combustion takes place in the bed with very intense mixing of gases and solids, high heat transfer to the furnace, and a low combustion temperature.
