<div class="yiv122968640moz-cite-prefix">Dear Ronal and Prof. Nurhuda,<br>
<br>
I too await the answers to Ron's questions. And add a comment
about what Ron wrote:<br>
<blockquote type="cite">you appear to be pre-heating both primary
and secondary air - can you attribute any performance
improvement to that? (I know of no-one else doing both)</blockquote>
I cannot think of anyone preheating primary air in a TLUD to any
significant degree. That is because there is no serious heat in
the lower areas of TLUDs until the pyrolysis front makes it at
least half way down the column of fuel. And then the heat is by
conduction through the metal sidewalls. <br>
<br>
Looking at the video by Nurhuda, I do not detect any effort to
pre-heat the primary air. He can clarify that for us. What is
important is the quality of the control of the amount of primary
air that can enter. VERY WELL DONE. His stove should be a
case study of industrial manufacturing of natural draft TLUDs.<br>
<br>
I request from Prof. Nurhuda as much additional information as
possible. The more that everyone and the GACC knows about the
Indonesia TLUD success story, the more opportunities there will be
for the further scaling up to serve people in Indonesia and
elsewhere.<br>

This is a really fine looking stove. The part that
intrigues me most is that you are controlling secondary air for
the pyrolysis gases. And apparently doing it (and primary air)
well with the rotating disc mechanism. I do not recall seeing
any other stove controlling both (without a fan) - so any data
on the value of that for users of the stove could be very
helpful to others. (Can they control excess air by the look of
the flame?)<br>
<br>
A few questions:<br>
<br>
the price?<br>
sales going well?<br>
what percentage char by weight?<br>
any soil improvement results from using the biochar?<br>
can you do more than a 4:3 turndown ratio? (based on your
two stated power levels)<br>
apparently you are striving for biochar (great!), but can
you describe conditions if you try to burn the produced char?<br>
any efficiency data?<br>
you appear to be pre-heating both primary and secondary air
- can you attribute any performance improvement to that? (I
know of no-one else doing both)<br>
<br>
Thanks for the alert on your stove.<br>
<br>
Ron<br>
