PROBLEM TO BE SOLVED: To provide a condensate re-evaporation device capable of reliably allowing condensate to flow to the downstream side from a re-evaporation tank irrespective of the inflow of condensate. SOLUTION: The condensate re-evaporation device is constituted by connecting a condensate feed pipe 2 and a communication pipe 8 to an upper part of a re-evaporation tank 1. A pressure sensor 9 and a pressure control valve 4 are fitted to the communication pipe 8 so as to be connected to a suction chamber 12 of an ejector 3, and a steam feed pipe 11 is connected to the ejector 3. In the condensate re-evaporation device, a part of condensate fed from the condensate feed pipe 2 to the re-evaporation tank 1 is re-evaporated, and sucked by the ejector 3 through the communication pipe 8. In this case, the inside of the re-evaporation tank 1 is maintained at a predetermined pressure state by the pressure control valve 4. Condensate in the re-evaporation tank 1 can be discharged to the downstream side from a condensate outlet pipe 5 without any stagnation. COPYRIGHT: (C)2005,JPO&NCIPI
