Pressurized fluidized bed combustion (PFBC) As with atmospheric FBC (CFBC or BFBC), the combustion temperature between 800-900°C has the advantage that NOx formation is less than in PCC, but N2O is higher. SO2 emissions can be reduced by the injection of a sorbent, and its subsequent removal with the ash.
The bed consisting of about 97% limestone or inert material and 3% burning fuel, is suspended by hot primary air entering the bottom of the combustion chamber. The bed temperature is controlled by heat transfer tubes immersed in the bed and by varying the quantity of coal in the bed.

“ (FBC) Fluidized bed combustion is a combustion technology used to burn solid fuels in steam boilers.” In Fluidized Bed Combustion Boiler technology When air or gas is passed through an inert bed of solid particles such as sand supported on a fine mesh or grid, the air initially will seek a path of least resistance and pass upward through the sand.
Boiler engineers can choose between two main types of fluidized-bed boilers—bubbling fluidized bed (BFB) and circulating fluidized bed (CFB). In BFB boilers the velocity of the combustion air is low enough that the fluidized particles remain in the lower furnace; in a CFB unit the velocity is greater and hot particles are circulated through the entire range of the boiler combustion zone.

Dec 24, 2018 · The fluidized bed combustion (FBC) takes place at about 840°C to 950°C for coal. Since this temperature is much below the ash fusion temperature, melting of ash and associated problems are avoided. Main reasons for consideration of Fluidized bed combustion Boiler :-Liberty of fuel choice – Normally fuel burns at 700 to 900 Deg C.
supplies combustion air for the atmospheric circulating fluidized-bed combustor that burns the char from the PCFB partial gasifier. • CHIPPS. A CHIPPS system is similar, but uses a furnace instead of an atmospheric fluidized-bed combustor. It also has gas turbine air
Atmospheric Fluidised Bed Combustion Boilers Atmospheric fluidised-bed combustion (AFBC) boilers offer efficient, cost effective and reliable steam generation. AFBC technology promises to provide a viable alternative to conventional coal-fired and other solid fuel-fired boilers.
Atmospheric Fluidised Bed Combustion Boilers. Global warming and Climate change is one of the most pressing and burning issues that needs urgent global action at all levels.
