<P>PROBLEM TO BE SOLVED: To provide a combination of a burner and an oxygen lance, and a method for the combination resolving danger and disadvantages of prior art. <P>SOLUTION: The oxygen lance is for high temperature gasification of waste comprising heterogeneous matter thermally treated beforehand when necessary. A channel for transporting reaction oxygen is formed identical to a channel for supplying combustion oxygen into a common channel, and a controller is included for controlling an amount of supplied oxygen in at least two different supplying states. In the method for operating the oxygen lance, the oxygen lance is permanently operated by flame of at least one burner, reactant fuel and oxygen are supplied in stoichiometric composition for the flame of the burner in a first operating mode, and in a second operating mode, oxygen is supplied to the fuel in an excessive stoichiometric composition and this portion of the oxygen enters into a high temperature reactor as a counterpart substance of reaction. <P>COPYRIGHT: (C)2004,JPO |
