Dear all,
i'm currently designing a vacuum system with steam ejectors followed by barometric intercondensers.

While I was able to find several vendor info on ejector steam flowrate per kg of suction gas, i didn't find data about ejector discharged temperature (a non isentropic compression is involved, i guess).

Does anybody have some suggestion/experience?

Thanks in advance.

In most cases, it is very difficult to predict the discharge temperature as the compression is far away from ideal. Complex thermodynamics associate with the process. Generally, using MP steam as motive fluid and suction fluid at temperature aroung 60 deg C discharges approximately at 160-180 deg C. Strictly, this is a very crude statement but ultimate calculations lies with ejector vendors and are proprietory in nature.
