Abstract: The present invention is directed to a method and apparatus for incinerating hazardous wastes through the use of a high temperature incineration process. According to the method of the present invention, substantially pure oxygen is preheated by partial combustion with a fuel such as kerosene. The partial combustion of the oxygen preheats the oxygen to a temperature which is sufficient to produce a hypergolic reaction when the oxygen is mixed with additional fuel. Turbulent flow is produced in the oxygen and simultaneously, a mixture of fuel and hazardous waste is atomized into the turbulent preheated oxygen, thereby quickly mixing the fuel, hazardous wastes, and oxygen. A hypergolic reaction is produced, producing high temperatures which break down the hazardous wastes. The apparatus of the present invention includes a oxygen pre-heater which partially combusts the oxygen and a cylindrical incinerator shell. A oxidant injector plate is disposed between the oxygen preheater and the incinerator shell.
