ABSTRACT:
Mixed refuse containing organic and inorganic material forms a column-like mass within a furnace chamber. The column of material is heated by a plasma torch having a forward plasma-emitting end disposed within the lower portion of the column and surrounded by the refuse therein. The height of the stack is maintained at a preselected elevation above the forward end of the torch. Gases produced by pyrolytic conversion of organic components of the refuse are discharged through ports of the chamber. Melted metallic and other inorganic refuse forms a pool upon a hearth of the furnace chamber. The plasma torch imparts circulatory movement to the pool. An injector downstream from the torch directs steam onto material adjacent the surface of the pool. Excess molten material is drained from the pool and the furnace chamber.
