<p>PROBLEM TO BE SOLVED: To provide a hybrid catalyst combustion method in which an amount of generated NOx can be restricted as much as possible. SOLUTION: A hybrid catalyst combustion device, in which there is provided a combustion chamber having a combustion flow passage formed therein, and also there are provided a catalyst combustion section 4 composed of combustion catalyst and a gaseous phase combustion section 5 placed at a downstream side of the catalyst combustion section, is used to cause a part of fuel to be ignited at the catalyst combustion section and further a residual part of the fuel to be ignited at the gaseous phase combustion section. There is provided a buffle member 6 at an inlet part of the gaseous phase combustion part near an outlet port of the catalyst combustion section, so as to be projected from a circumferential part of the combustion chamber into an indoor side, wherein its rear end inner location is formed as an edge part and a flow passage kept in its released state is formed. A re-circulating region extending along the inner wall of the combustion chamber is formed at the downstream side of the buffle member, gas in the re-circulating region is cooled from the inner wall of the combustion chamber, and combustion is carried out.</p> |
