description Biomass gasification apparatus includes: gasification reaction furnace; upper supply unit configured to supply woody biomass and inert gas from above through feeding hole to furnace; lower supply unit configured to supply mixed gas containing inert gas from below to furnace; sensor configured to detect clogged state in which biomass is clogged in hole; and controller configured to control supply units to regulate upper supply flow rate of inert gas supplied by upper supply unit and lower supply flow rate of inert gas supplied by lower supply unit based on detection result by sensor. When clogged state is detected, controller increases upper supply flow rate to be higher than first flow rate and decreases lower supply flow rate to be lower than second flow rate so that sum of upper supply flow rate and lower supply flow rate is maintained at predetermined flow rate.
