GASIFICATION FURNACE METHOD OF OPERATING GASIFICATION FURNACE AND BIOMASS GASIFICATION TREATMENT METHOD

摘要

A gasification furnace 10 that can obtain a synthetic gas comprises the following: a biomass supplying unit 2; a water vapor supplying unit 3; a reaction tower 4 in which a first region R1 and a second region R2 are formed along the gas flow direction and in which biomass supplied from the biomass supplying unit 2 is caused to flow in the first region R1 by an entrained bed formed by the water vapor supplied from the water vapor supplying unit 3 and gas generated in the first region R1 is caused to flow into the second region R2; a plurality of oxygen gas supplying units 5 (5a 5b 5c) that supply oxygen gas to the first region R1 and the second region R2 of the reaction tower 4; and a supply amount adjusting mechanism that adjusts the amounts of oxygen gas supplied from the oxygen gas supplying units 5 (5a 5b 5c).
