Method for improving the operation of a fluidized bed

摘要

A method of operating a fluidized bed in which a bed of particulate combustible material is disposed on a perforated plate and air is introduced through the plate and into the bed to fluidize and promote the combustion of the material. Additional particulate material, of a size less than that of said combustible particulate material, is introduced to the bed so that it is entrained in the air to maintain the combustible material in the bed.
