を特徴とする蒸気熱交換装置。 Compressed air is circulated in a steam heat exchange device that heats with the latent heat of condensation of steam by connecting a steam pipe 6 to the inlet of the steam heat exchanger 1 and a drain pipe 7 with a steam trap 8 interposed to the outlet thereof. An air pipe 9 is branched and connected to the steam pipe 6, and a first on-off valve 10 is interposed in the air pipe 9, and a second on-off valve is provided in the steam pipe 6 upstream of the branch connection part of the air pipe 9. 11, a drain pipe 13 having a third on-off valve 12 is provided to bypass the steam trap 8, and a temperature detector 14 is further provided to detect the temperature around the steam heat exchanger 1. Further, in response to a signal generated by the temperature detector 14 when detecting a low temperature that causes freezing of the drain, an output to open the valve is issued to the operation section of the third on-off valve 12, and a heating operation command is issued to the third on-off valve 12 to open the valve. An output to open the valve is issued to the operating section of the second on-off valve 11, and an output to close the valve is issued to the operating section of the second on-off valve 11 in response to a heating operation stop command;
A steam heat exchange device characterized in that a control means 15 is provided on the operating section of the first on-off valve 10 to issue an output for opening the valve only for a predetermined period of time.
