PROBLEM TO BE SOLVED: To obtain a heat exchanger capable of securely discharging generated steam condensate to the outside of a container via a steam trap. SOLUTION: A steam supply pipe 3 is connected to a jacket 2 via a control valve 7. The jacket 2 and a liquid pressure-feeding member 5 are connected via check valves 11, 12. The jacket 2 and the liquid pressure-feeding member 5 communicate with each other via a communication pipe 14. The liquid pressure-feeding member 5 is connected with a high-pressure steam supply pipe 15. A pressure-feeding port 17 of the liquid pressure-feeding member 5 is connected to a liquid ejector 6. A suction chamber 10 of the liquid ejector 6 is connected to an outlet side of the steam trap 4. The outlet side of the steam trap 4 is brought into a predetermined low-pressure state by a suction force generated by the liquid ejector 6, and the steam condensate can be securely discharged to the outside.
