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

Message-ID: <42F812A1CF574A238B33CED7CDEFE230@DimitrisPC>
Content-Type: text/plain; charset="utf-8"

Hello all.
Has anyone ever tried to use the genset exhaust of a syngas driven genset in order to use it in a biomass dryer(rotary or something)? I can read in the literature that the syngas engine?s exhaust is saturated, but I cannot find experimental data anywhere. What does ?saturated? mean in numbers of relative humidity (%) or absolute humidity (gr/kgr)?

Best Regards
Dimitris

Hallo Dimitris,

no idea if syngas exhaust behaves differently from diesel exhaust, but the latter comes out at around 400 ?C and can be very well used to dry wet biomass. It should be mixed with ambient air so as not to pyrolize or even ignite the biomass.
I once spoke to people from Central America who had a very simple setup:
A sort of tower where the raw biomass is filled in at the top and the exhaust/air comes from below in counterflow. They said that the humidity was driven off to the top and dry stuff could be taken out below.
Seems simple...

best regards

Rolf
