    My experience is somewhat dated, but even fairly recent marine steam turbine power plants included steam-powered devices called "air ejectors" (basically a Venturi suction tube) whose main purpose was to reduce the turbine condenser pressure very close to an absolute vacuum in order to maximize turbine efficiency. But they also removed  noncondensible gases, mainly nitrogen and oxygen, from the steam. The discharge of the air ejectors went into another condenser that removed the the residual condensed steam, returning that water to the steam cycle, while venting the noncondensible gases to the atmosphere.

About the NRG

If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.

The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.

The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
