PROBLEM TO BE SOLVED: To deodorize and detoxicate odorous gas such as ammonia. SOLUTION: A secondary combustion chamber 2 is connected to a primary chamber 1 burning fuel and generating a combustion flow turning like a vortex from a lower part toward an upper part, and an outlet of the secondary combustion chamber 2 is connected to an exhaust chamber 3. Combustion gas from the primary combustion chamber 1 is burned at high temperature in the secondary combustion chamber 2, and it is passed through the exhaust chamber 3 and an exhaust duct 14 by an exhaust fan 5 and discharged to an exterior. The secondary combustion chamber 2 has a combustion chamber 21 and a gas holding chamber 22, and an opening 272 communicated with the gas holding chamber 22 is provided in a periphery part of a secondary chamber inlet part 24 connecting a primary combustion chamber outlet part 17 and the combustion chamber 21. Air supply ducts 30, 31 and an odorous gas duct 28 are connected so as to freely open and close to the gas holding chamber 22. COPYRIGHT: (C)2008,JPO&INPIT
