DEVICE FOR THERMOCHEMICAL CONVERSION OF BIOMASS INTO ENERGY GASES

摘要

The invention relates to a device for thermochemical conversion of heterogeneous biomass into low-tar content energy gases, which after further cooling and purification can be used as energy for propulsion of engine groups, installations and gas turbines. The device comprises a housing body and cores formed therein, including a pyrolysis, oxidation and reduction zone, wherein a nozzle for supplying an oxidizer is provided in the oxidation zone. A separation shield (4) is mounted in the cylindrical part of the housing body (1), in which a pyrolysis zone (6), a first oxidation zone (7), a reduction zone (8) and a second oxidation zone (9) are formed, and external to the housing body (1) there is a casing (10), which completely encloses the housing body (1) and is divided into a lower and an upper parts by means of a barrier (11) located in the area of a grate bar (3) at the lower part of the casing (10). Along the periphery of the housing body (1), are mounted nozzles (12, 13) in the two oxidation zones (7, 9) to supply the oxidizer. A pipeline (15) is mounted centrally in the housing body (1), with a chamber (16) fixed at its lower end, the lower part of which has a perforated surface (17). Inside the chamber (16) is mounted a vibrating body (18), at the height of which are inclined shielded elements (19), and on the inner wall of the chamber (16) are mounted reflective elements (20), oriented opposite to the shielding elements (19).
