Activated charcoal is prepared at high temperatures, and has
minimal volatile matter to assist with ignition and for
maintaining easy combustion. Needs high temp to get it burning
again.<br>

<div dir="ltr">Hello Dr. Anderson, everyone,<br>
The coconut meat has a high level of oil, which adds increase
BTU heating values to the fuel.<br>
I have tried pelletized activated carbon ( coconut shell
feedstock ) in a standard wood pellet stove, but did not work
well.<br>
However minor modification of the burn chamber should correct
that.<br>

<br>
THANKS for your reply. It provides encouragement for
further discussion.<br>
<br>
Would you please do the following:<br>
1. Tell us more about yourself and your activities in
Honduras, including where in that country.<br>
2. What is the size of the TLUD you use with the coconut
husk and nut fuel?<br>
3. What is the arrangement for the combustion of the
pyrolytic gases?<br>
4. Do you utilize the heat that is created from those
gases?<br>

<div dir="ltr">I have worked with coconut, husk
sometimes just the coir and sometimes the coir an
shell together, sometimes with the coconut meat
inside. Here in Honduras coconuts are sold in
roadside stands mostly for the water. After the
water is drank out with a straw the the nut, shell,
husk and all is thrown in a pile beside the stand.
I dry the resulting nuts and burn them in a TLUD or
in a slash pile. The coir simply falls apart, into
powder when carbonized and the shell needs some
mechanical processing. I can't say how good the
resulting biochar is because I mix with other types
of biomass. But the whole or half nuts burn well in
a TLUD.</div>

<div> <br>
<div>Thank you, Michael, for your
insightful coments (below). Here are
some thoughts in response:<br>
<br>
1. I focus on places where husks and
shell accumulate. What is processed
is wonderful. May it continue and
prosper. But there are piles (I have
been assured) in many places.<br>
<br>
2. I am envisioning piles of husks
(skin, pith, and coir), some with
shell still attached. Perhaps in
shape of about 1/3rd to 1/5th of the
whole coconut. Some might still be
intact. A pile in the sun. could
be spread out for sun-drying. A bit
of dirt or sand does not matter.<br>
<br>
3. If the shell is actually separate
(because of prior processing), it is
an issue of smashing tough
semi-spherical pieces of shell. SMASH
without much concern about some of the
pieces becoming too small should NOT
be of much concern. Allow for some
waste of "too small" pieces. Lift a
substantial weight and let it fall
requires effort,but I suspect that
someone can make some suggestions that
yield a net gain because the shell is
SOOOOO good as a TLUD fuel. Like
pellets in some ways. And pellets
require substantial energy to be made.<br>
<br>
4. Mainly about the husk pieces (but
possibly related to shell also), I
want to suggest and discuss the drying
and even the partial (maybe full??)
torrification of that biomass. After
all, WASTE heat is one of the abundant
leftovers of burning pyrolytic gases
created when making char/biochar.
So, TOAST the stuff!!! Really, that
is more of a question than a
statement.<br>
<br>
5. What do we know about the
torrification of husks (and of shells)
of coconuts? Can somebody find out,
please? First requirement is that
you need some husks (and shells)
(sorry, I do not have any). After
that, put heat to it any way you want
to. If torrified husk (or shell) can
be then appropriately sized for use in
TLUDs or any other combustion device,
that would be progress.<br>
<br>
Comments (and maybe results?) are
requested.<br>
<br>
Paul<br>
