BIOMASS GASIFICATION DEVICE Russian patent published in 2022 - IPC C10B49/18 C10B53/02 C10J3/12 C10J3/22 C10K3/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to a biomass gasification device. Biomass gasification device comprises a biomass pyrolysis reactor having a biomass inlet and a non-oxidising gas inlet and/or a steam inlet; a pyrolysed gas reforming reactor having a steam inlet and a reformed gas outlet; pyrolysed gas feed pipe for feeding pyrolysed gas produced in the biomass pyrolysis reactor into the pyrolysed gas reforming reactor, wherein the pyrolyzed gas inlet pipe is located between the biomass pyrolysis reactor and the pyrolysed gas reforming reactor, in which the biomass pyrolysis reactor further comprises an input port and an output port for a plurality of preheated granules and/or lumps and is configured to pyrolysis of the biomass using the heat of the plurality of granules and/or lumps, and the pyrolysed gas reforming reactor is configured for steam reforming the pyrolysed gas produced during the biomass pyrolysis, pyrolysed gas reforming reactor additionally comprises an air or oxygen inlet and performs steam reforming with partial combustion of pyrolysed gas produced during pyrolysis of biomass, using air or oxygen; pyrolysed gas inlet pipe is located on the side surface of the biomass pyrolysis reactor at a level below the upper surface of the layer of a plurality of granules and/or pieces formed in the biomass pyrolysis reactor, note here that inner bottom surface of pyrolyzed gas feed pipe comprises element extending upward.

EFFECT: optimization of biomass pyrolysis temperature.
