<P>PROBLEM TO BE SOLVED: To provide an evaporator capable of reducing the pressure loss of a hot gas in the evaporator. <P>SOLUTION: The evaporator 1 to generate a fuel vapor for reforming the fuel by gasifying a liquid fuel containing hydrocarbons is equipped with a hot gas straight moving passage in which the hot gas flows straight in the horizontal direction, an evaporation passage 36 installed capable of making heat exchange with the hot gas straight moving passage, a fuel supply pipe 60 to supply the liquid fuel to the evaporation passage 36, and vapor passages 17 and 18 installed upstream of the hot gas straight moving passage farther than the vapor passage 36 in such a way as capable of making heat exchange with the hot gas straight moving passage and heating the fuel vapor exhausted from the evaporation passage 36, The fuel vapor generated in the evaporation passage 36 flows therein upward in the gravitational direction, is introduced into the vapor passages 17 and 18 upon being exhausted from the upper part of the passage 36, and flows inside the vapor passages 17 and 18 in the gravitational direction. <P>COPYRIGHT: (C)2004,JPO |
