PURPOSE: A fluidized-bed combusting device with improved air dispersion performance and ash re-discharging performance is provided to induce an active mix of a fluidized-bed by discharging fluidized air to various lower directions and to combust solid fuel more stably and efficiently by inducing the downward discharge of incombustibles. CONSTITUTION: A fluidized-bed combusting device with improved air dispersion performance and ash re-discharging performance comprises a furnace(110), an air supply pipe(120), air dispersing nozzles(130), an air nozzle cap(140), and an incombustibles discharge unit(150). The furnace receives fluidized substances and solid fuel in inside and combusts the same. The air supply pipe of an inner hollow pipe shape is installed in the outside of the furnace, thereby supplying fluidized air to the furnace. The air dispersing nozzles are branched from the air supply pipe, are inserted inside the furnace, and blow the fluidized air to the inside of the furnace. The air nozzle cap is arranged in the upper part of the air dispersing nozzle and downwardly jets the fluidized air discharged from the air dispersing nozzles. The incombustibles discharge unit discharges the incombustibles discharged from the lower part of the furnace to one direction after cooling the same. |
