ABSTRACT:
An apparatus for drying, pyrolyzing and possibly also gasifying of lump wood in a cylindrical vessel with a hearth case includes a vessel of a type which differs from prior art vessel units by a top cooling hood with an annular cooling duct and an outer annular air space for preheating suction air and an inner, likewise annular, gas space to discharge to some external destination the gas recovered from the predried wood. The air drawn from the outer annular space is fed to the hearth via an air chamber and nozzles. Condensate precipitated on the inside faces of the hood drops into an annular gutter and is subjected to evaporation in the further course of the process. A method for operating this apparatus is also provided.
