[0002] Exhaust steam refers to low-pressure and low-temperature steam that is discharged from the exhaust port after steam has completed work and its thermal potential energy has been converted into kinetic energy.

The blowdown steam can be first separated by the steam-water separator 110, then compressed and heated by the steam compressor 120, and then the temperature of the blowdown steam can be exchanged by the heat exchanger 130.
