PURPOSE:To realize low NOx combustion and to prevent the generation of pollution by providing a catalyst type main combustion device and burner type auxiliary combustion device to a combustion part for heating a reactor of a reformer and regulating the ratio of supplying gases to both combustion devices with regulators. CONSTITUTION:A gaseous raw material such as LNG is introduced together with steam from an inlet nozzle 111 into the reformer 110 and is subjected to reforming reaction in a reforming catalyst layer 112. The reformed gas is taken out of an outlet nozzle 114. Part of a anode waste gas 216 of a fuel cell is supplied to the catalyst type main combustion device 210 and is burned therein. The balance is supplied to the burner type auxiliary combustion device 213 and is burned therein so that the heat necessary for the reforming reaction is generated. The temp. of the catalyst in the device 210 in this stage is detected by a thermocouple 214a and the ratio of the waste gas 216 to be supplied to the device 210 and the device 213 is regulated by the regulators 214 in accordance with the detected value by which the temp. of the catalyst is controlled to a prescribed value. |
