<p><P>PROBLEM TO BE SOLVED: To provide a method for gasifying a woody biomass, by which the production of clinkers can especially be prevented. <P>SOLUTION: This method for gasifying the woody biomass, comprising using a down-draft type fixed bed gasification oven 6, charging a raw material comprising the woody biomass into the upper portion of the oven on the upper side of a partition plate 65, and blowing an oxidizing agent from a blowing port 67 into the oven to gasify the woody biomass, is characterized by blowing steam from the blowing port 67 into the oven. The down-draft type fixed bed gasification oven 6 is manufactured by disposing the partition plate 65 for dividing the inside of the oven into the upper and lower portions, disposing a vertically penetrated passage hole 66 in the lateral center of the partition plate 65, and disposing blowing ports 67 for blowing an oxidizing agent to the lateral center of the inside of the oven from a peripheral portion which is above the partition plate 65 and not above the penetrated passage hole 66. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
