PURPOSE:To make a uniform distribution of temperature in a catalyst layer, provide a small-sized device and save energy by a method wherein an interior of a surge tank of a metallic case provided with some dispersion materials for dispersing reaction gas and catalyst is divided into a plurality of small chambers. CONSTITUTION:Interior of a surge tank of a metallic case 11 for a catalyst combustion device is divided by metallic plates 14 and the like to form some small chamber 15 which are divided for every specified surface area of the catalyst. Reaction gas is supplied into the metallic case 11 and then guided into the metallic case 11, further guided into the small chambers 15, passes through the dispersion materials 12 at the front surfaces of the small chambers and the catalysts 13 and contributes in the reaction. Therefore, it is possible to restrict the disturbance of distribution of temperature of the catalyst surfaces.
