can any one help?

RE: steam ejector

Ejectors don't "create" the vacuum.  They maintain it by removing non condensables that would 'blanket' condensing surface and retard or prevent condensation.

Not to be confused with a "hogging jet" or vacuum pump that does in fact pump out air and non condensables so that condensation can begin to take place.  But once it does, the collapse of the vapor being condensed 'creates' and maintains the vacuum.  The jets just insure that it can continue against leakage into the system of non condensables.

Another place to look (I am not going to google it for you) is www.Graham-mfg.com
