Abstract: Provided is a gasification furnace that can efficiently gasify a biomass resource. The gasification furnace may include a furnace body including a cylindrical storing unit that may store a biomass resource, an oxidizer supplying unit that may supply an oxidizer into the furnace body, a shaft extended in a vertical direction in the storing unit and including an oxidizer supply path through which the oxidizer may be passed, an oxidizer supply tube that may include an oxidizer channel that communicates between a supply port for the oxidizer opened in an outer surface in contact with the biomass resource in the storing unit and the oxidizer supply path of the shaft, and a driving unit that may rotate the shaft with the vertical direction in the storing unit set as a rotation axis to thereby turn the oxidizer supply tube in the storing unit.

Abstract: A gasification furnace for gasifying a biomass resource in a manner producing a low quantity of tar. The gasification furnace (10) is provided with a punching plate (11) partitioning the furnace interior into upper and lower spaces; a biomass resource supply port (10a) for supplying the biomass resource over the punching plate (11); a first oxidizer supply port (10c) and a second oxidizer supply port (10d) for supplying an oxidizer into the furnace; a first oxidizer supply path supplying the oxidizer from the first oxidizer supply port (10c) from above towards below the punching plate (11); a second oxidizer supply path distributing and supplying to a plurality of locations within a predetermined area in the vicinity of the punching plate (11) from the second oxidizer supply port (10d); and a dry distillation gas output (10b) for discharging dry distillation gas generated by the pyrolysis and partial oxidation of the biomass resource on the punching plate (11) to the outside.
