<DIV>Dear all,</DIV>
<DIV>tar is a valuable byproduct. Villagers buy it from a hardware
shop at about US$1 per kg. So, we would prefer not to burn
it. </DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial># What do they use the tar for? What kinds of
"tars" can tehy use, and for what purposes? Mpre specifically...</FONT></DIV>
<DIV><FONT size=2 face=Arial>1: Can they use the "blackwater" from gas
scrubbing?</FONT></DIV>
<DIV><FONT size=2 face=Arial>2: Do they perhaps only use "whole tar" as would,
for example, be produced by trapping tars from a charcoal retort?</FONT></DIV>
<DIV><FONT size=2 face=Arial>3: Do they perhaps only use a selected fraction
of the "tar"</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial># Your comments wil be very helpful.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Thanks.</FONT></DIV>

<DIV>Dear Doug, Brian and all</DIV>
<DIV><BR></DIV>
<DIV>To what extent can you clean today's gas by passing it (cooled to about
150 C) through a barrel of tomorrows REASONABLY DRY fuel, thus
permitting you to burn all the tars AND finish drying the fuel?</DIV>
<DIV><BR></DIV>
<DIV>While a moisture content less than 20% is desirable for gasifier fuel,
I suspect it should not be bone dry for long runs because it becomes
autopyrolytic and won't retain a level pyrolysis zone.</DIV>

<DIV>Oh goodness yes! We've not been willing to TOUCH the compression
challenges until we got our gas pretty darn clean. I'm cautiously
optimistic with where we are at on that task:</DIV>

<DIV>And right now we're planning on three separate compression steps with
additional filters between each step.</DIV>
