Abstract
Problem to be Solved To provide a waste gasification melting apparatus which, even if a fuel gas is used as an alternative to a part of the coke, the temperature of the coke bed can be sufficiently raised, and a method using the same. Solution A waste gasification melting apparatus including an oxygen rich air supply apparatusfor blowing oxygen rich air into a tuyere, and a fuel gas supply apparatusfor supplying a fuel gas to the tuyere, and a controllerfor controlling the oxygen rich air supply apparatus; the oxygen rich air supply apparatusmixing air and oxygen to prepare oxygen rich air and supply the oxygen rich air to the tuyere; and the controllercontrolling the amount of air to be mixed and the amount of oxygen to be mixed in the oxygen rich air supply apparatusso as to give an oxygen concentration of the oxygen rich air in accordance with the amount of fuel gas supplied to the tuyerefrom the fuel gas supply apparatus
