Heat medium heating type reforming device
专利汇可以提供Heat medium heating type reforming device专利检索，专利查询，专利分析的服务。并且PURPOSE:To easily prevent the temp. of reforming catalyst when the reforming operation is stopped from rising over the upper limit of allowable temp. by constituting the titled device especially so as to effectively use a heat medium expansion tank connected to a heat medium circulation line as a heat radiator. CONSTITUTION:When the reforming operation of the reforming device 2 and the operation of a heat medium boiler 3 are stopped due to the stoppage of operation of a fuel cell 1, passage change over valves 14, 15 are respectively changed over to 'open' and 'close' by the direction from a control panel 16. By this change-over, the heat medium expansion tank 9 is connected in series in the heat medium circulation line 4, and the heat medium of high temp. flowing in the line 4 is sent into the tank 9 through a connecting pipe 13. The heat medium of high temp. is mixed with the heat medium of low temp. retained in the tank 9 to be cooled, and is returned through a connecting pipe 12 of the opposite side to the line 4 and to the reforming device 2. As a result, the temp. of the heat medium circulating through the line 4 is reduced, and the heat medium cools the reforming catalyst in the reforming device 2 on the way of circulation to reduce the temp.，下面是Heat medium heating type reforming device专利的具体信息内容。
