From one of the sides among a heat-storing body (6a) at one end and a heat-storing body (6b) at the other end of a primary reforming oven (4), an alternating syngas introduction system (7), while alternating therebetween, introduces a syngas into flow passages (4a, 4b), at the same time, a primary alternating oxidant supply system (8), while alternating therebetween, supplies an oxidant to the syngas. The syngas is withdrawn from the primary reforming oven (4) by an alternating syngas withdrawal system (9) and led toward a secondary reforming oven (10). Connected to the secondary reforming oven (10) is a secondary oxidant supply system (11) whereby the introduced syngas is supplied with oxidant only at the time of alternation in the alternating syngas introduction system (7) and the alternating syngas withdrawal system (9). |
