<br>
Julien's excellent research was presented at ETHOS and should soon
be available to all via the ETHOS website. It is already
available at the drtlud.com website:<br>
<a class="moz-txt-link-freetext" href="http://www.drtlud.com/wp-content/uploads/2015/02/Winter-Julien-ETHOS-2015.pdf">http://www.drtlud.com/wp-content/uploads/2015/02/Winter-Julien-ETHOS-2015.pdf</a><br>
<br>
There are many slides, including the one in discussion.<br>
<br>
1. Refreshing my memory: the control of the gasification rate
was by changing the grate (8 of them) at the bottom, to allow more
(or less) primary air to enter for a specific fuel (6 fuels on the
graph). <br>
<br>
And where is the temperature measured? At the fuel bed when the
Migratory Pyrolytic Front (MPF) was there. Correct?<br>
<br>
2. I am not understanding well the measurement <br>
that is stated as g / m*2 s (grams per square meter x s )<br>
I was expecting something more like the weight of the fuel per
minute. Is the m meters or minutes?<br>
I do understand the concept that greater gasification rate would
result in higher temperature. <br>
<br>
3. There are approximately 115 to 120 data points. How many of
them are repeated tests using the same combination of air control
and fuel type?<br>
<br>
Julien's work is a great example of meticulous scientific
research. AND he did it at his home facilities without external
funding. <br>
<br>
Much appreciated!!<br>

<div>Hi All;</div>
<div><br>
</div>
<div>This discussion about stove testing started off about
"gaming the test".</div>
<div><br>
</div>
<div>I doubt there are many stove developers who would want
their test "gamed." What they would like to know is if their
stove is reliable, or if it fail under certain conditions. It
would be a bit of a nuisance to get a glowing report on your
stove, only to discover later that it had problems.</div>
<div><br>
</div>
<div>The question I ask is whether the protocols of the water
boiling test 4.2.3 are sufficient? Do we need to be explicit
about scientific methods, or do we just assume that "everybody
knows that".</div>
<div><br>
</div>
<div>I have attached a slide from the presentation I gave at
ETHOS. Notice the range of gasification rates when a variety
of fuels are used. What would you do to make sure that you
are not "counting white swans" when conducting a water boiling
test?</div>
<div><br>

<div>Cheers,</div>
