METHOD FOR FEEDING MATERIAL INTO BOILER OF REFUSE INCINERATION FACILITY

PROBLEM TO BE SOLVED: To use a simple method for feeding a reducing agent that reduces nitrogen oxides into a boiler of a refuse incineration plant. SOLUTION: In this method for feeding the reducing agent into the boiler 4 of the refuse incineration facility using a gas propellant, the reducing agent is introduced from at least one distributor 8 and then introduced to nozzles 16a-16i allocated to respective lines of a plurality of lines 14a-14i branched from the distributor 8, and the reducing agent and the gas propellant are fed into the boiler 4 by the nozzles 16a-16i. The amount of the reducing agent introduced from each of the nozzles 16a-16i is set in the distributor 8. The reducing agent and the gas propellant are mixed upstream of branched pipes forming each of the lines 14a-14i, so that the feeding amount of the reducing agent for each of the nozzles 16a-16i using the simple structured nozzles 16a-16i can be individually set, and the optimum reduction of nitrogen oxides can be positively performed while taking into consideration both a local temperature difference and a time-based variation in temperature.
