ABSTRACT:
An apparatus and a method are disclosed for the thermal treatment of feed material containing solids and liquids such as solid waste or the like. The apparatus includes one or more coaxial rotatable drums and one or more free rotating spirals advancing the material in the drums. The material flowing through the drums is heated to form solids and vapors. In one or more embodiments of the apparatus, the hot solids and vapors exchange heat with the cold feed material. An extruder for preparing the solids being produced from the apparatus for disposal and a means for rotating the drums are also disclosed.
