Patent ID: 7156886

Claim:
A reforming apparatus for producing a reformed gas from a fuel gas and steam, comprising: a combustion gas passage; and a reformed gas-producing passage configured to receive a fuel gas and steam, the reformed gas-producing passage comprising a first passage formed adjacent to the combustion gas passage and a second passage positioned downstream from the first passage and formed adjacent to the first passage, wherein the reformed gas-producing passage includes a second heat-recovering section in the first passage, a reforming catalyst section downstream from the second heat-recovering section in the first passage, a shift catalyst section downstream from the reforming catalyst section, a CO-selective oxidizing catalyst section downstream from the shift catalyst section, and a first heat-recovering section in the second passage adjacent to the reforming catalyst section, and the second heat-recovering section is positioned adjacent to at least one of the shift catalyst section, the CO-selective oxidizing catalyst section and a section of the reformed gas-producing passage between the shift catalyst section and the CO-selective oxidizing catalyst section.
