Title: Fuel reforming apparatus
Inventor: MIZUSAWA MINORU
IPC: H01M8/10
Filed: 2004-02-12
Abstract: A fuel reformer, wherein reforming tubes (13) are stored in a flow passage (12) between a furnace tube (11) disposed in the inner tube (9a) of a vacuum heat insulation container (9) and the inner tube (9a), a clearance for raising combustion gas (28) generated in a combustor (10) therethrough is formed between the furnace tube (11) and a guide tube (21) stored in the furnace tube (11), a spiral plate (22) is installed in the flow passage (12) so that the combustion gas (28) flowing down in the flow passage (12) flows across the reforming tubes (13). Thus, the furnace tube can be sufficiently red-heated to sufficiently heat the reforming tubes by radiant heat transfer, and accordingly the heat transfer area of the reforming tubes can be reduced to reduce the size of the reforming tubes. In addition, the upper ends of the reforming tubes are not exposed to high temperatures, and since drift is not caused in the combustion gas flowing downward between the inner tube of the vacuum heat insulation container and the furnace tube, an input heat quantity for each reforming tube is uniformed to increase the performance of the reformer and to reduce the size thereof.
