The oxidation catalyst mat 4 is made of alumina fibers and one layer each of cobalt and silver. Furthermore, back panel 3
A fuel reformer 5 is installed between the oxidation catalyst mat 4 and the oxidation catalyst mat 4. The fuel reformer 6 is constituted by a triple tube, as shown in the cross section in FIG. There is. Further, one end of the fuel reformer 5 serves as a mixed gas supply port 9 of hydrocarbon gas and air, and the other end serves as a produced gas discharge port 1o. The mixed gas supply port 9 communicates with a hydrocarbon gas supply port 11 and an air fan 12 . The reforming catalyst 6 used was one in which 10 w% of nickel was supported on a torlumina integrally molded with a lattice-like cross section.

ミング触媒６は部分酸化反応を開始する。Further, an amount of natural gas having a stoichiometric ratio (m value) of 1.2 to 1.4 with respect to this air amount is similarly sent to the fuel reformer 6 via the mixed gas supply port 9. In the fuel reformer 5, a flame is formed on the flame port plate 7 by the spark plug 8, and the reforming catalyst 6
At the same time, this exhaust gas is discharged from the generated gas outlet, and at the same time preheats the oxidation catalyst mat 3 to 6o to 90°C. When the reforming catalyst 6 is preheated to 700 to 80 degrees Celsius (5'.
Increase the amount to about 0.38. As a result, the reforming catalyst 6 starts a partial oxidation reaction.
