Abstract
A fluidized-bed combustion system for a boiler, a heating furnace for heating steels or the like, in which a plurality of gas distribution pipes are disposed at the bottom of the combustion chamber. The lower end of each gas distribution pipe is communicated with an air supply line with an air flow rate control valve and a fuel supply line with a fuel flow rate control valve and the air and fuel admitted into the gas distribution pipe are mixed within the same and the air and fuel mixture is injected or sprayed into the fluidized bed through injection ports of the gas distribution pipe which are positioned adjacent to the bottom of the fluidized bed, whereby the complete combustion within the fluidized bed can be ensured and the combustion can be controlled over a wide range and optimized depending upon a load.
