Shaft gasifier for operation at a substoichiometric oxidation

摘要

Shaft gasifier for the production of fuel gas of solid carbonaceous material, comprising:— A a shaft gasifier the inside space surrounding the shaft wall (12),— A in the shaft gasifier is arranged on the inside space pyrolysis zone (23) with— a solid - supply opening (21a) for the supply of solid carbonaceous material in the shaft gasifier,— a solid - outlet opening (22a) for the removal of part of the tem carbonaceous solid,— a gas - outlet opening (24) for pyrolysis gas— a in the shaft gasifier is arranged on the inside space oxidation zone (43), which, in thermal contact with the pyrolysis zone, with— a gas - supply opening (41a, perhaps in d) in conjunction with the gas - outlet opening of the pyrolysis zone for the supply of pyrolysis gas from the pyrolysis zone,— a gas - outlet opening (44), andcharacterized in that the oxidizing zone (43) between the pyrolysis zone (23) is arranged and of the shaft wall.
