WIPO Patent Application WO/2014/157466

A1

Provided is a waste gasification and melting device and method capable of increasing the temperature of a coke bed sufficiently even when using fuel gas as a substitute for a portion of the coke. A waste gasification and melting device having an oxygen-rich air supplying device (14) that supplies oxygen-rich air, by blowing, to a tuyere (5), a fuel gas supplying device (15) that supplies fuel gas to the tuyere (5), and a controlling device (5) that controls the oxygen-rich air supplying device (14), wherein the oxygen-rich air supplying device (14) prepares the oxygen-rich air by mixing air with oxygen and then supplies the oxygen-rich air to the tuyere (5), and the control device (16) controls the amount of air and the amount of oxygen that are mixed by the oxygen-rich air supplying device (14) so as to set the concentration of oxygen in the oxygen-rich air according to the amount of gas fuel supplied to the tuyere (5) from the fuel gas supplying device (15).
