<div>We had three women interns here at the research center
for a summer who found cleaner burning recipes for the
TLUDs gathered from the surrounding forest. Some things
like bark make smoke, etc.</div>
<div><br>
</div>
<div>Many pellets smoke when using eucalyptus, etc.
Different mixtures of kerosene make more or less smoke in
off the shelf stoves.</div>
<div><br>
</div>
<div>I'm wondering if torrified pellets will burn cleaner
than normal pellets.</div>

I remember that there was a proposed university
program (W. Virginia or the Carolinas??) In view of
the deaths(not _many_ but tragic) that have taken
place due to off-loading of pellets at some European
ports (CO in the hold) The torrefaction could lead to
a more inert fuel. That's hopeful speculation on my
part however. You would be transporting some less
bound water and the energy density is better than
regular pellets in addition to the lack of liquid or
vapor H2O absorption issue mentioned before-- these
would lend efficiencies in the logistics end of things
and an even more uniform fuel than regular pellets,
which tend to absorb quite a bit of water here in the
damp winter weather...<br>
I have to admit that I'm a bit puzzled as to what you
mean by cleaner fuel recipes. What specific pollutant
are you interested in or are you talking about
particulate?<br>
If you aren't choking the burn by putting the pot too
close, you should be getting a very clean burn with a
TLUD?!?<br>

<div bgcolor="#FFFFFF" text="#000000"> Hi
Dean,<br>
I did some searching around on the
internet several years ago on this
topic.<br>
I'd like to try torrefied stuff as well,
but I struck out at that time.<br>
No idea where to find them.<br>
The main advantage that I picked up on
at that time was that they should be
relatively inert as to picking up extra
water after they were pelletized.<br>
Cleaner burning than what?<br>
clean burning is a control issue, not a
fuel issue as far as I understand. If I
understand the concept correctly, it's
like using part of the large molecules
initially broken out (cracked) by the
heat in the reaction vessel to coat the
surfaces of the remaining unpyrolized
material. This should burn quite okay in
a TLUD.<br>
