Dear Kirk, Paul and all,<br>
<br>
Kirk: thanks for circulating your hypothesis. This seems
well-founded.<br>
Paul: measuring long-chain hydrocarbons / tars is part of the
planned project of PhD student Thomas Kirch.<br>
<br>
The intention is to measure the tars fairly soon. The catch is that
our existing micro-GC isn't suitable for this, and finding someone
who is willing to put our tars in their GC-MS is proving difficult.
Until we get funds to buy our own, any suggestions for other ways of
characterising the tars?<br>
<br>
Cheers,<br>
Paul<br>

The Wonderwerk Man has again done wonderful work!!!! Stove
Summit, Stove Camp, assisting Dennis (who then won the Cat Pee
award), and cooking with Flip. It is always a pleasure being with
you.<br>
<br>
The hypothesis (explanatory document) is well done. All serious
stove researchers should read it. Where is this document being
placed for public access. I offer to place it at the
drtlud.com website. (Send your reply to James Schoner directly
or via the Stoves Listserv; I will be in Mexico for the next 13
days).<br>
<br>
Hypotheses are statements that ask to be confirmed. The folks
with the scientific equipment can now step in and see if the
long-chain hydrocarbons are indeed breaking up when and where
indicated by the hypothesis. Good if that could be soon, but I
expect not. In the meantime, the excellent low emissions (which
are facts, not hypotheses) speak for themselves.<br>
<br>
The needed scientific studies would help answer several questions
such as whether all three steps (levels) are needed to accomplish
the low emissions and the ability for turn-down to low fire.<br>
<br>
About turndown such as when cooking in Flip's oven, a different
solution is to have a second gasifier reactor (fuel chamber) that
has a smaller diameter.<br>
<br>
Keep up the good work!! (werk)<br>

<div><font face="Arial" size="2">Talking about stoves at the
InStove Stove Summit and Aprovecho Stove Camp made me think
through the workings of our Wonderwerk TLUD-ND. I needed
to create a working hypothesis of why it burns as cleanly as
it does. Attached is the hypothesis. It may not be
completely correct, but it does provide an explaination, or
at least a place to start an explaination. There is a
lot that I don't know about this burning method and a lot
of work left to be done.</font></div>
<div> </div>
<div><font face="Arial" size="2">At Stove Camp, Sam
Bentson, Aprovecho's lab engineer offered to help me probe
into the pressure variations in the stove. I was sadly
involved with too many things to take him up on it. My
loss! What I did do was to support Dennis, a visiting
student from China, in his development of a wok support with
skirt and chimney. </font> <font face="Arial" size="2">He
tested it on top of the latest Wonderwerk TLUD-ND stove and
the results were impressive. He made several adjustments to
the dimensions which seemed to improve its performance even
more. He required only high power and no turn-down.</font></div>
<div> </div>
<div><font face="Arial" size="2">After Stove Camp I visited with
Jon and Flip Anderson. We put an older Wonderwerk TLUD-ND
under one of their clay ovens, and baked a cake. It
required two fuel (vertically arranged split sticks of an
unknown variety of hardwood) loadings of the stove, the
first to heat the oven and give about 30 minutes of baking
and the second finished the 1 hour baking time. This showed
the need for turn-down capability for oven baking.
The latest Wonderwerk stove, which I had left at
Aprovecho, would very likely have done it with only one load
of fuel, because of better turn-down and more efficient
burning.</font></div>
