Which operation mode is better when the door rod leaks air?

It would be better to run like this with steam.

The steam leakage system of steam turbine shaft seal and valve stem is an important part of steam turbine, and its main function is to provide sealing steam to the shaft seal, main steam valve and valve stem seal of regulating valve. In the high and medium pressure cylinder section of steam turbine, the function of shaft seal system is to prevent steam leakage, thus ensuring the high efficiency of steam turbine.

In the area of low-pressure cylinder of steam turbine, the function of shaft seal system is to prevent outside air from entering the turbine and ensure that the turbine has as high vacuum and high efficiency as possible. The shaft seal system is mainly composed of sealing device, shaft seal steam main pipe, shaft seal heater and other equipment, as well as corresponding valves and piping systems.
