ABSTRACT:
Process and apparatus for treating a comminuted solid carbonizable material, such as comminuted municipal waste; sawdust, granulated coal, shredded tires and the like wherein the material is caused to be pyrolyzed in a horizontally disposed elongated reaction zone essentially free of any oxygen containing gases at ambient pressure and at a temperature of from 400.degree. C. to 900.degree. C. The material is passed through the reaction zone by paddle-like impellers mounted on a shaft while being subject to an indirect heat transfer relationship via a burning air fuel mixture spirally swirling within a heating zone about the reaction zone and the mixture being withdrawn from a lower portion of the heating zone. During pyrolysis, the material is chemically changed into valuable gaseous, liquid and solid products.
