PURPOSE:To provide a catalyst combustion chamber integrated, heat-exchanger type reforming device for which the dispersing property of a combustion gas emitted from a catalyst combustion section of a combustion device is improved. CONSTITUTION:A catalyst combustion chamber integrated heat-exchanger type reforming device is constituted of a heat-exchanger type reforming chamber being equipped with a bayonet type catalyst tube 1 with a double tube structure, and a catalyst combustion chamber which is provided under said heat-exchanger type reforming chamger, has a catalyst bed to burn an exhaust gas by oxygen inside, and the cross section of the refining chamber of which is small, and a porous dispersion plate 31 is provided in the combustion chamber and on the top of the catalyst bed at an exit. In this way, a combustion gas is uniformly dispersed, and therefore, the degrees of reaction at respective catalyst tubes become equal, and a local excessive reaction or insufficient reaction can be prevented from taking place. |
