Abstract
At a center portion of a ceiling wall of a furnace body having a lateral wall between the ceiling wall and a bottom wall, there is a burner that combusts downwards. A reforming reaction tube is provided in a circumference of the burner to carry out a steam reforming treatment on a source gas. A discharging portion is an opening at an upper side portion of the lateral wall for discharging combustion gas of the burner. A cylindrical outer wall is disposed at an outer side portion of the lateral wall. In an outside space formed between the lateral wall and the outer wall, there is a steam generating heat exchanger generating steam or a mixture gas of a source gas and steam. At a lower side portion of the outer wall, there is outside discharging opening discharging the combustion gas which flows through the outside space.
