PROBLEM TO BE SOLVED: To provide a waste heat-recovering/pressure-reducing device for steam capable of regulating steam pressure supplied from a steam ejector sucking re-evaporated steam with high accuracy, and allowing the condensed water to surely flow down from a steam trap mounted on a condensed water supply pipe to a re-evaporation tank. SOLUTION: An upper part of the re-evaporation tank 1 and a suction chamber 12 of the steam ejector 3 are connected. A steam supply pipe 9 is connected with the steam ejector 3, and a pressure control valve 10 is mounted. A pressure control valve 4 is mounted on an upper part of the re-evaporation tank 1 through a pipe conduit 24. The condensed water supplied from a condensed water supply pipe 2 to the re-evaporation tank 1 is partially re-evaporated, and sucked to the steam ejector 3 through a communication pipe 8. The remaining condensed water flows down into a liquid pressure-feed member 7 from a liquid inflow port 15 of the liquid pressure-feed member 7 disposed at a lower part. COPYRIGHT: (C)2007,JPO&INPIT
