<P>PROBLEM TO BE SOLVED: To solve a problem that a conventional hydrogen producing apparatus has poor utilization efficiency of a gas in starting up. <P>SOLUTION: The hydrogen producing apparatus is provided with a reforming part 1 for producing a reformed gas from a hydrocarbon based raw material gas and steam, a combustion part 7 for heating the reforming part 1, air blowing part 8 for supplying air to the combustion part 7, a reforming part temperature detecting means 13 for detecting the temperature of the reforming part 1, an evaporating part 3 for supplying steam to the reforming part 1, a switch valve 11 for introducing the reformed gas produced in the reforming part 1 and/or the raw material gas passed through the reforming part 1 into one of the combustion part 7 or an apparatus 12 for utilizing the reformed gas and a control means 16 for controlling the combustion part 7 so that a detected temperature by the reforming part temperature detecting means 13 becomes equal to or below a 1st prescribed temperature at which carbon deposition reaction does not proceed when the reforming part 1 is purged by the raw material gas in the starting up and the combustion part 7 is ignited by supplying the raw material gas passed through the reforming part 1 through the switching valve 11. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
