Abstract:
1. A method for converting waste materials to vapor and char utilizing a pyrolytic processing oven comprising: a) an outer refractory insulated containment vessel employing a fired heating means and suspended within said outer vessel, b) an inner containment vessel constructed of materials conducive of transferring heat said inner vessel configured in a shape whereby the vessel bottom is in the form of an inclined chute with a higher and lower end, c) a waste material inlet conduit that penetrates both the outer and the inner vessels said conduit perpendicular to the upper side wall of both the outer and inner vessels and with the shape of the inner vessel in the form of a circle at the location of the said inlet conduit with the bottom portion of the circle forming the upper end of the bottom chute, d) a char discharge conduit located at the lower end of the said inclined chute formed bottom with said discharge conduit penetrating both the inner and the outer vessels with the shape of the inner vessel at the location of the said discharge conduit being in the form of an obround circle with its minor dimension equal to the diameter of the said circle shape of the vessel at the point where the inlet conduit penetrates the inner vessel, e) and a vapor outlet conduit penetrating both the inner and outer containment vessels located on the obround shaped end of the inner vessel at a location above the char discharge conduit.
