PROBLEM TO BE SOLVED: To provide a reforming device whose entity including auxiliaries is downsized, and which can prevent local heating, and drastically reduce heat radiation that is an energy loss by an internal combustion reforming method. SOLUTION: The reforming device of hydrocarbon gas by an internal combustion reforming method is equipped with a double pipe which consists of an inner pipe and an outer pipe arranged concentrically with spaces, where, an oxidative reaction tube filled with oxidative catalyst in the inner pipe, and a reforming reaction tube with reforming catalyst filled between the inner and the outer pipe are provided, and also a burner heating the inside of the reforming device at the time of driving is arranged at an upper end in the oxidant reaction tube, and hydrocarbon gas, steam, air are circulated from the upper end in the oxidant reaction tube for oxidative reaction, then circulated to the reforming reaction tube after turning back from a lower end, hydrocarbon gas is reformed to reforming gas. |
