<P>PROBLEM TO BE SOLVED: To provide an evaporator that miniaturizes an unavoidable structure part on the periphery of an evaporator body to the limit. <P>SOLUTION: The evaporator, which recovers heat energy by using heating evaporation of water in a double tube structure, is constructed so that the interior of a structure part arranged on the periphery of the evaporator serves as a passage of a steam/water mixture of steam and hot water. <P>COPYRIGHT: (C)2004,JPO |
