High temperature oxygen hazardous waste incinerator
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. Passages formed in the oxidant injector plate inject the preheated oxygen into the incinerator shell creating a turbulent flow into which the fuel and hazardous wastes mixture is atomized. The hypergolic reaction takes place within the incinerator shell and the combustion products are exhausted. A flow controller valve may be provided downstream of the incinerator shell in order to partially block the flow gases therefrom to increase the back pressure within the incinerator shell and thereby increase the residence time of the hazardous wastes.
