摘要：<p>PROBLEM TO BE SOLVED: To realize a catalyst combustion device, capable of realizing the improvement of high temperature durability and the enlargement of width of variable combustion amount compared with a conventional catalyst combustion device. SOLUTION: A catalyst combustion device is provided with a primary combustion chamber 11, in which a catalyst body 12, provided with the mixture of fuel and air inlet port arranged at the upstream side, an exhaust gas outlet port arranged at the downstream side and a catalyst body 12, in which Pt or an oxidizing catalyst primarily consisting of Pt is bored on a substrate having a multitude of communicating ports, are arranged, the secondary supplying port 13 of mixture or air, which is provided at the downstream side of the combustion chamber 11, and a secondary combustion chamber 14, provided at the downstream side of the secondary supplying port 13. Upon combustion, the air excessive rate of the primary combustion chamber 11 becomes not more than 1 in a case when a predetermined condition is satisfied.</p>
