PROBLEM TO BE SOLVED: To provide a steam heat exchanger capable of promptly discharging condensation generated in an interior of the heat exchanger to the outside. SOLUTION: A steam supply pipe 2 is connected to an inlet header 7 of a multistage press 1. An inlet side pressure sensor 3 is attached to an upper part of the inlet header 7. An outlets side pressure sensor is attached to an upper part of an outlet header 10, and a control valve 5 is connected below it. The control valve 5 is communicated with a gas-liquid separator 12. An ejector 18 and a circulating pump 19 is connected below the gas-liquid separator 12. An excessive condensation discharge pipe 21 is connected to a thermomagnetic engine 25. By controlling opening and closing of the control valve 5 in response to a detection value from each pressure sensor 3 and 4, a predetermined differential pressure is maintained, and the condensation generated in the multistage press 1 is quickly discharged.
