<DIV><FONT face=Arial size=2><STRONG>Hi Gasification
Colleagues,</STRONG></FONT></DIV>
<DIV><STRONG><FONT face=Arial size=2></FONT></STRONG> </DIV>
<DIV><STRONG><FONT face=Arial size=2>My promised separate Fluidyne Update to
this forum is late coming together, but you can see a new Progress
Report on the Fluidyne Archive <A
href="http://www.fluidynenz.250x.com">www.fluidynenz.250x.com</A> of the Mk8/9
Andes Class development project being done in California. Having been home just
11 days from this last test programme for 2010, I feel a bit flat, and quite
frankly, gasified out.</FONT></STRONG></DIV>
<DIV><STRONG><FONT face=Arial size=2></FONT></STRONG> </DIV>
<DIV><STRONG><FONT face=Arial size=2>It's so pleasing to see the really
interesting and diverse views being presented this week on the Gasification List
about exhaust heat and it's moisture. I certainly see some of this stuff more
than most, but don't have the luxury of wondering about what it is or isn't,
only if it is a clean emission within standards. In this context, you may find
one of the photos of the Tecogen CHP engine of interest. It show the exhaust
poring out steam in the first part of it's start-up sequence. It's so cold after
the catalytic heat exchanger, they use a silicon rubber hose to make the muffler
connection. The steam fades as the engine comes up to operational speed and
output, but is running on LPG in this photo.</FONT></STRONG></DIV>
<DIV><STRONG><FONT face=Arial size=2></FONT></STRONG> </DIV>
<DIV><STRONG><FONT face=Arial size=2>Unfortunately, we were not able to do the
gas conversion over to producer gas, but did manage to run it long enough to
establish that it was delivering the derated 41 kWe on producer gas.
Normally on LPG, it delivers just over 70 kWe, so we were happy to see the
derating confirmed. I should mention, that the derating and confirmed output was
straight out of the Fluidyne Engine Tables, so if you chose to use them, know
they are about as accurate as you can find for aspirated engine
performance.</FONT></STRONG></DIV>
<DIV><STRONG><FONT face=Arial size=2></FONT></STRONG> </DIV>
<DIV><STRONG><FONT face=Arial size=2>For 2010, our work on site had the benefit
of a gas analyser to provide a record for our research into how the packed
carbon bed evolves from wood/charcoal/gas, and in the process, push the bed
beyond historical practice. It puts new meaning into stuffing a forest
through a funnel! We did 72 recorded runs, with strip down, bed analysis,
photos parameter change or modification, in the mornings, then reassembled and
test run in the afternoons. Operating data was then sent to me for comment
in preparation for the next days internal inspection, and we repeated it all
over again and again. Tough on the guys on site, but my hands didn't even get
dirty thanks to SKYPE.</FONT></STRONG></DIV>
<DIV><STRONG><FONT face=Arial size=2></FONT></STRONG> </DIV>
<DIV><STRONG><FONT face=Arial size=2>Have a look at the Archive report in the
mean time, and I will get back to you as time allows.</FONT></STRONG></DIV>
<DIV><STRONG><FONT face=Arial size=2></FONT></STRONG> </DIV>
<DIV><STRONG><FONT face=Arial size=2>Trust this is of some
interest.</FONT></STRONG></DIV>
