Circulating fluidized bed combustion for biomass boiler. 2017-6-13 · Efficiency of the CFB Combustion Process. 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.

Features of bubbling bed boiler Fluidised bed boiler can operate at near atmospheric or elevated pressure and have these essential features: • Distribution plate through which air is blown for fluidizing. • Immersed steam-raising or water heating tubes which extract heat directly from the bed.

A temperature deviation in any part of the furnace and cyclone of less than 20°F from a preset temperature can be achieved at operating temperatures of up to 2650°F with the large internal and external solids recirculation rate. Other applications of the circulating fluid bed for high temperature, endothermic reactions, such as
