Hi Nicolo.
Thank you (but I believe that giving me an offer is irrelevant to the
purpose of this list, isn't it?)
Now to the point:
According to my calulations, if we consider that a saturated genset exhaust
stream is @ 415 oC with absolute humidity of 800 gr/kgr (stream A, this is
what I ask - if its humidity is correct) and we mix it 50%-50% with ambient
air of 25 oC with 50% relative humidity(stream B), the resulting stream will
be a mixture of about 220 oC with an absolute humidity ~400 gr/kgr(stream
C).
This mixture stream C has a drying potential, but I do not know if the
assumption on stream A is correct.
Any ideas?
Best Regards
Dimitris

Dear Rolf,Leland,Nicolo
thank you for your replies,
but still I got no clue what "saturated" genset exhaust looks like from
physics point of view...
Anybody?
Best Regards
Dimitris
