ABSTRACT:
A method and apparatus for the high temperature destruction by pyrolysis and incineration of organic and inorganic gaseous, liquid, and solid toxic and hazardous compounds. The apparatus has a melting chamber and a combustion chamber wherein solid, sludge liquid and gaseous compounds are separately or simultaneously eliminated. In the melting chamber of the apparatus, a molten mass media operates at temperatures between 2200 and 2900 degrees F. Directly above the molten mass a flame impinges upon the molten surface at a temperature of 3000 degrees F. and above. Solid, liquid, and gaseous hazardous wastes are introduced into the melting chamber either on or beneath the surface of the molten mass wherein the waste is destroyed. Due to the operating sequence of the apparatus, the liquid and solid waste compounds may be in the molten mass in excess of eight hours. In addition, hazardous liquids may be mixed with liquid fuels and introduced into the upper combustion chamber as the combustion media at temperatures of 3000 degrees F. Hazardous gases and particulate may also be introduced into the upper combustion chamber and mixed with the gases in the combustion media and are in the chamber in excess of four seconds. The final product is cooled and may be reused in part in a subsequent charging batch.
