PURPOSE: To improve the thermal efficiency and the furnace efficiency by supplying fuel in multiple stages in the longitudinal direction of a refoming pipe to burn partially, eliminating local heating with catalystic burning, and reducing the burning temp. lower than that of ordinary method.
CONSTITUTION: As for heat supply means 300, heat generating means consisting of the combination of a fuel supply chamber means 39 and a burning catalyst bed means 30 are provided in multiple stages in the longitudinal direction. The fuel supplied from each fuel supply means 34 is flowed through the heat supply means 300 with the oxygen containing gas supplied from an oxygen gas supply side to a burnt gas discharge end 48, and burnt in each burning catalyst bed means 30 to generate heat and discharged from a gas discharge opening means 49. On the other hand, the raw material to be reformed supplied from a supply passage means 9 is passed through a reforming catalyst bed 20 with the steam supplied at the same time, and supplied with the heat generated at the means 300 to be changed into reformed gas, which is taken out through a taking-out means 21.
