The primary driving force for development of fluidized bed combustion is reduced SO2 and NOx emissions from coal combustion. Bubbling fluidized bed (BFB) combustors are of interest for plants with a nominal boiler capacity greater than 10 MW th. Circulating fluidized bed (CFB) combustors are more suitable for plants larger than 30 MW th.

Fluidized Bed Combustion FBC Boiler - Boilersinfo

" (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.

The benefits of fluidized bed combustion are the possibility to use several different fuels simultaneously, simple and cheap sulfur removal by injecting limestone into the furnace, high combustion efficiency, and low NOx emissions. The two main types of fluidized bed combustion are: the bubbling fluidized bed boiler (BFB) and the CFB boiler.

BFBC Boiler Design Principles • Bubbling bed boilers are short and stocky because. O The low heat release rates make the plan area large. O A residence time of 2.0-2.5 s makes the freeboard only —6 m, even for larger boilers. • With nearly 60-70% of evaporation taking place in the bed coils, the boiler bank load is greatly reduced.
