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 …

Fluidized Bed Combustion. Atmospheric fluidized beds use limestone or dolomite to capture sulfur released by the combustion of coal. Jets of air suspend the mixture of sorbent and burning coal during combustion, converting the mixture into a suspension of red-hot particles that flow like a fluid. These boilers operate at atmospheric pressure.

In this boiler, higher fluidizing air velocity (3.7–9.0 m/s) results in the coal and inert bed material being entrained and carried through the combustor and overboard region into the hot cyclone. Thus, a distinct dense fluidized bed does not exist at higher load in this case.

Fluidized Bed Boilers Versus Pulverized Fuel Boilers The choice of technology of Fluidized Bed Combustion (FBC) Boilers over the conventional Pulverized Fuel (PF) Boilers has several reasons. FBC boilers can handle a wide range of fuels with low heating values (as low as 1500 kcal/kg), high ash content (as high as 55 per cent) and high sulphur content.

A fluidized bed boiler feed system for the combustion of pulverized coal. Coal is first screened to separate large from small particles. Large particles of coal are fed directly to the top of the fluidized bed while fine particles are first mixed with recycled char, preheated, and then fed into the interior of the fluidized bed to promote char burnout and to avoid elutriation and carryover.
