<p>PROBLEM TO BE SOLVED: To prevent a deterioration of a body or an interior of the body at a temperature of an exhaust gas by providing a plurality of ribs in an exhaust port provided at a combustion unit, and separating the gas. SOLUTION: The catalytic combustor comprises a fuel tank 3 for filling a fuel gas, an operating unit for operating a supply, ignition and stop of the gas, and a combustion unit 2 for burning the gas. A combustion chamber 2a having an oxidizing catalyst 7 is disposed in the unit 2. The chamber 2a is formed in a cylindrical shape, and the catalyst 7 of a honeycomb structure is disposed at its center. The chamber 2a is separated by the catalyst 7 to an upper part of a suction chamber 8 and a lower part of an exhaust chamber 10. A communicating port 11 for passing an exhaust gas in association with a catalytic combustion is provided at a side bottom of the chamber 10. An exhaust port 13 for exhausting an exhaust gas in association with the catalytic combustion passed through the port 11 is provided at the upper part of the chamber 2a. The port 13 is provided in an annular state to surround a heat sink plate 9. A plurality of ribs 14 are provided in the port 13. The plurality of ribs are made of ceramics or metals.</p> |
