PROBLEM TO BE SOLVED: To provide a condensate re-evaporation device capable of increasing re-evaporation amount of condensate in a re-evaporation tank without discharging high-temperature condensate from the re-evaporation tank. 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 liquid force-feed member 7 is disposed on a predetermined lower part of the re-evaporation tank 1 and connected via a condensate outlet pipe 5. A temperature regulating valve 23 is fitted to the condensate outlet pipe 5. 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, and the remaining condensate flows down into the liquid force-feed member 7 from the temperature regulating valve 23 only when the temperature of the remaining condensate is low.
