Abstract

Abstract An apparatus for disintegrating and incinerating a concentrated slurry of solid organic material. The apparatus having an arcuate tunnel, a series of pairs of arc forming electrodes spaced along and mounted within said tunnel and electrical source means connected to each pair of said arc forming electrodes. Advancing means continuously to advance a layer of the organic material through the arcuate tunnel and consecutively into juxtaposition to the arcs formed between each of the pairs of arc electrodes wherein the temperature of that portion of said organic material in juxtaposition to each of said pairs of arc forming electrodes is abruptly raised to from about 2,000* F. to about 15,000* F., at which temperatures the bonds between the carbon and other atoms are dissolved, and means to maintain an oxidizing atmosphere within said tunnel.
