WASTE GASIFICATION MELTING EQUIPMENT AND WASTE GASIFICATION MELTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide waste gasification melting equipment and a waste gasification melting method capable of preventing deterioration of combustion rate of fuel gas even when blast flow rate of oxygen-enriched air quantity to be blown into coke bed is deteriorated.SOLUTION: Waste gasification melting equipment includes: an oxygen-enriched air supply device 14 provided for each tuyere 5 so as to perform blow supply of oxygen-enriched air to the tuyere 5; a fuel gas supply device 15 provided for each tuyere 5 so as to supply fuel gas to a plurality of tuyeres 5; and a control device 16 which independently controls each fuel gas supply device 15. Therein, the oxygen-enriched air supply device 14 at each tuyere 5 has a flow meter 17 which measures blast quantity of oxygen-enriched air to each tuyere 5, and the control device 16 controls fuel gas supply quantity from the fuel gas supply device 15 at the corresponding tuyere 5 in accordance with a measured value on the flow meter 17 of the oxygen-enriched air supply device 14 at each tuyere 5 such that a ratio of the blast quantity of oxygen-enriched air at each tuyere 5 to fuel gas supply quantity falls into a predetermined range.
