Will the non-condensable gases in the steam definitely be discharged from the higher points?

Question: Regarding the issue of non-condensable gas discharge in steam systems, if the non-condensable gas is air, will installing a high-point vent valve definitely ensure that the air is discharged? Air is denser than water vapor; why is it released from higher points?
Sure, it’s all water below; there’s no issue with density.

Hello, we’re from the laboratory. If the combined pressure of steam and air is 0.1 Mpa, what is the temperature threshold?

I’m sorry, I’m not familiar with this. There should be relevant software or documents available for reference; my views are based on my own experience in actual production or operation.
Should this be called dew point?
