<P>PROBLEM TO BE SOLVED: To provide a reforming apparatus where sealing properties are secured without increasing cost, and a high temperature fluid can efficiently be fed to an evaporation part with a simple constitution. <P>SOLUTION: The reforming apparatus 20 is composed of: a reforming part 60 producing a reformed gas from fuel and leading out the same; a combustion part 50 heating the reforming part 60; and an evaporation part 30 producing water vapor and feeding the same to the reforming part 60. The evaporation part 30 is formed into the cylindrical one provided with adjoining internal and external two annular passages 30b and 30a, and is further coaxially arranged so as to be opposed to the reforming part 60 with a space in-between. An annular passage 56b formed between the reforming part 60 and the evaporation part 30 is communicated with the internal passage 30b of the evaporation part 30 at the tip parts. Combustion gas made to flow in from one end of the annular passage 56b is made to flow into the internal passage 30b at the other end, and is made to flow out from one end of the internal passage 30b. On the other hand, water made to flow in from one end of the external passage 30a in the evaporation part 30 is made to flow out from the other end of the external passage 30a. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
