Abstract: An incinerator is provided having an extended length of tubing, preferably coiled, and immersed within a bath of molten salt. Means are provided for introducing sludge at a controlled rate along with hot air under pressure for carrying the sludge through the immersed length of tubing, the air and the heat supplied from the molten salt bath causing concurrent drying and burning of the sludge. The exhausted gases are further oxidized by passing them through a portion of the molten salt bath, while solids are separated out and removed.

Abstract: A solid-liquid waste incinerator is disclosed which provides a novel thermodynamic interaction between a liquid catalyst, which is employed for cleansing the exhaust gases from the incinerator, and a combustion stage in which the solid-liquid wastes are burned, thereby reducing their volume by about ninety percent. Generally, solid-liquid wastes are introduced into a combustion chamber, and are initially heated by indirectly contacting molten salts or other hot liquid catalysts. A burner disposed directly above the wastes also heats the wastes to produce combustion of the wastes into exhaust gases and a greatly reduced volume of ash residue. During the combustion process, the burner, together with the heat produced from the combustion of the wastes, act to reheat the liquid catalyst.
