Bubbling or Circulating? 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.
A bubbling fluidized bed (BFB) boiler is a boiler that can also handle fuels that are difficult to pulverize or less combustible. The fuel is introduced into a mixture of sand flowing at high temperatures, allowing the fuel to be efficiently combusted.
A bubbling fluidized bed boiler comprises a fluidizing grate through which primary combustion air passes and a containing vessel, which is either made of (lined with) refractory or heat-absorbing tubes. The vessel would generally hold bed materials with or without heat absorbing tubes buried in it.
In a fluidized bed boiler, hot air is blown at a high velocity up through a bed of sand, limestone, and ash causing the solid particles to fluidize, or behave like a liquid. Fluidization provides good mixing and allows for effective combustion when fuel is added.

“ (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.
Figure 12.5 depicts a typical underfeed bubbling bed boiler. There is a bottom/grid/distribution plate consisting of sand/ash and fuel. Evenly spaced air and fuel nozzles as well as ash nozzles for ash discharge are attached to the bottom plate. After preheating, air is admitted to fluidize the bed, followed by the fuel feeding.
