Fluidized Bed Combustors for Biomass Boilers - ASME

Boiler engineers can choose between two main types of fluidized-bed boilersbubbling 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.
