Abstract: A device for producing fuel gas from materials of organic and/or inorganic origin, comprising filling chamber connected to at least one supply auger conveyor for supplying material from the filling chamber into a reactor comprising at least two heated gasification augers. The invention consists in the fact that each horizontal row of gasification augers is formed by a gasification body, the casing of which has a closed oval cross-section formed by an upper base, a lower base, and convex side walls each with circular arc profiles, wherein each gasifying body contains at least two gasification augers arranged side by side and mutually partially separated by longitudinal partitions that form half-grooves for gasifying augers. The device is provided with at least one electrical heater. The filling chamber is hermetically sealed.

Abstract: An apparatus (10) for the passage and conveyance of compressible material, the apparatus (10) comprising at least two arrays (14) of substantially parallel first screw conveyors (16) each arranged at an outlet (56) of a vessel (12) from which the material is to be conveyed such that the material is conveyed to respective second screw conveyors (18) arranged in generally transverse relation thereto, wherein the material to be conveyed bears directly on the first screw conveyors (16) from above and does not bear directly on the second screw conveyors (18). A method for the passage and conveyance of compressible material is also described.
