Bubbling Fluidized Bed or Stoker — Which is the Right

Review of fluid bed technology The term "fluidized bed" is derived from the process that takes place in the lower part of the boiler. The lower furnace or "bed" of a BFB boiler is charged with an inert medium such as sand, which is initially brought up to temperature by using auxiliary fuel. Once at temperature, the auxiliary fuel is shut
