<P>PROBLEM TO BE SOLVED: To supply water having stable temperature to a reformer using the heat of reaction in a carbon monoxide removing apparatus. <P>SOLUTION: This fuel reforming system is provided with a reformer 12 for producing a reformed gas, a carbon monoxide selective oxidization reactor 13 for removing carbon monoxide in the reformed gas, a heat exchanger 50 for exchanging heat between the heat of carbon monoxide removing reaction and water in the carbon monoxide selective oxidization reactor 13, a flow control valve 3 for controlling water to be supplied to the reformer 12 and a heater 4 for heating the water. The calorific value in the carbon monoxide selective oxidization reactor 13 is calculated based on the temperature of the reformed gas in the upstream side of the carbon monoxide selective oxidization reactor 13 and the change amounts concentration of hydrogen and carbon monoxide in the upstream side and the downstream side of the carbon monoxide selective oxidization reactor 13 and the heating amount of water by the heater 4 is controlled so that the temperature of the water after the heat exchange becomes a prescribed value based on the calorific value and the temperature of the water before being introduced into the heat exchanger 50. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
