| 摘要 |
The present invention provides a device which makes it possible not only to significantly decrease the hassle caused by tar and the like generated by pyrolyzing biomass and to maximize the rate of gasification of the tar generated, but also to produce hydrogen-containing gas from biomass at high thermal efficiency and low cost. A gasifier device, provided with: a biomass pyrolysis zone for heating biomass in a non-oxidizing gas atmosphere; and a gas reforming zone for heating, in the presence of steam, pyrolyzed gas thus generated; a plurality of heated granules and/or lumps being moved from the gas reforming zone to the biomass pyrolysis zone to reform pyrolyzed biomass gas and to pyrolyze biomass using the heat possessed by the plurality of granules and/or lumps. The gasifier device is characterized in that the biomass pyrolysis zone and the gas reforming zone are provided in a single vessel, and at least one partitioning plate is provided between the biomass pyrolysis zone and the gas reforming zone. |
