CATALYST COMBUSTION DEVICE

摘要

PURPOSE:To provide a catalyst combustion device, maintaining excellent burning characteristics and having larger TDR. CONSTITUTION:The title device is constituted so that a premixture flow passage for passing the premixture of fuel and air, a catalyst layer 7, provided at the downstream side of the premixture flow passage to make catalitic combuation, and an exhaust gas flow passage 9 for passing exhaust gas generated in the catalyst layer 7 are provided while the premixture passage and the exhaust gas flow passage 9 are formed on both sides of a common tube wall 8 to preheat the premixture by the heat of the exhaust gas.
