ABSTRACT:
A waste material, particularly refuse, is conveyed through a combustion chamber while simultaneously being mixed and is treated with a gaseous oxidizing agent. The combustion chamber comprises a rotary tubular furnace. The waste material is acted on by the gaseous oxidizing agent, with the volatile combustible constituents of the waste material forming flames with the oxidizing agent. The radiation heat of the flames frees additional volatile constituents of the waste material. The waste material freed of volatile constituents is obtained as refuse coke and the unburnt volatile constituents are obtained as combustible gas. The thermal treatment in the rotary tubular furnace can be continued beyond the freeing of volatile substances. Given an adequate temperature rise, the oxidic constituents of the slag formed are melted, and the latter can be obtained in the form of glass.
