<P>PROBLEM TO BE SOLVED: To properly keep the temperature of a carbon monoxide selective oxidation apparatus in which the sufficient quantity of steam is rapidly obtained in start-up and carbon monoxide is selectively oxidized in preference to hydrogen. <P>SOLUTION: A line for cooling a carbon monoxide selective oxidation part 30 of the fuel reforming apparatus system 20 is provided with a first cooling line 40 connected to a first cooling passage 34 of the carbon monoxide selective oxidation part 30 and of taking out cooling water as steam and a second cooling line 50 for cooling the carbon monoxide selective oxidation part 30 by circulating a cooling medium in a circulation pipe line including a second cooling passage 36. In the start-up of the system, the flow route of a hydrogen enriched gas is changed so that the cooling water in the first cooling passage 34 is receiving a large amount of heat by a flap 38 to rapidly heat the cooling water and the required quantity of steam is rapidly taken out. In the normal operation, the carbon monoxide selective oxidation part 30 is cooled by the second cooling line 50 and water in a steam generator 60 is heated by the heat generated in the time to stably obtain the required quantity of steam. <P>COPYRIGHT: (C)2008,JPO&INPIT |
