PURPOSE:To improve uniformity in the temp. of catalyst in a fuel reformer and to increase the average heating temp. of the catalyst by arranging heat conductors such as metallic wires in the longitudinal direction in the reforming chamber packed with the catalyst. CONSTITUTION:Cylindrical members 2, 3, 12, 13 are sealed in an external container 24 to form chambers 4, 14, and heated gas generated from a burner is fed along the chambers 4, 14. When the heated gas flows along the chambers 4, 14, the gasification of a fuel mixture is caused in the chamber 4, and the reforming of the gasified mixture is caused in the chamber 14. Heat conductos 31 such as long metallic wires 32 are arranged in the chamber 14 in the longitudinal direction of the chamber 14. The heat of the heated gas is conducted in the diametral direction. The wires 32 conduct some of the heat in the axial direction, so the heating of catalyst 15 at the front end of the chamber 14 is reduced, and the heating of the catalyst 15 at the rear end is increased. Accordingly, the catalyst is uniformly heated as a whole, and a high average temp. is attained. |
