TUYERE BLOWING METHOD FOR COMBUSTIBLE DUST IN WASTE MELTING FURNACE

PROBLEM TO BE SOLVED: To provide a tuyere blowing method for combustible dust in a waste melting furnace capable of reducing equipment cost and maintenance cost for tuyere blowing of combustible duct, and monitoring the inside of the furnace from the tuyere at all times, so that the optimum operating action can be implemented at the perfect time. SOLUTION: This method is applied to collect combustible dust scattering from the waste melting furnace 1 provided with a plurality of tuyeres 13 at an outer periphery of a furnace bottom portion at intervals, and blow the same into the waste melting furnace from the tuyeres 13. The combustible dust collected from partial several tuyeres 13 among the plurality of tuyeres 13 is blown with the oxygen-enriched air, and only the oxygen-enriched air is blown from the remaining several tuyeres 13 without blowing the combustible dust.
