<P>PROBLEM TO BE SOLVED: To solve such problems that in a reforming chamber, in order to efficiently raise the temperature of fuel gas to reaction temperature, installation of a heating chamber separately from the reforming chamber to preheat the fuel gas before supplying to the reforming chamber is desired, but this makes system constitution complicated. <P>SOLUTION: A fuel gas passage 10 is divided through a partition wall 9 in at least three sides of surrounding of a square reforming chamber 7, the heating chamber 14 to which combustion heat from a combustion chamber 8 is transmitted is installed, a plurality of fins 15 extending in the front and rear direction are installed in parallel on the inside of the reforming chamber 7 to divide a reaction gas passage 13, the fuel gas 3 is made to flow from an inlet 10a at one end of the heating chamber 14 and to flow through the fuel gas passage 10 while heated, supplied to a rear end part of the reforming chamber 7 through an outlet 10b at the other end of the heating chamber 14, the fuel gas 3 entered in the reforming chamber 7 is guided with fins 15 and advanced through the reaction gas passage 13 to form reformed gas 2, and the reformed gas 2 is made to flow out of a reformed gas outlet 4 at the front end of the reforming chamber 7. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
