The answer to the question you ask me is this. The char that is
produced in a TLUD stove is removed and is NOT used in any burning
that relates to the TLUD stove that made it. The char comes out.
Where it goes is not an issue here. <br>
<br>
I thank you for your EXCELLENT comments. Informative. Long, but
that is a compliment. Something useful was written.<br>
<br>
However, your reply still does not address my question about char
values (weight or energy) being used in all those other stove
testing methods. I await an answer. <br>
<br>
Your comments about about big systems was interesting:
<blockquote type="cite">As far as I know, in general all tests of
thermal performance such as power stations, fixed boilers, heating
stoves and cooking stoves
<i>in the formal sector</i><span> treat solid resides with energy
content remaining as a 'mechanical loss'. That is the definition
of a mechanical: unburned fuel that could in theory have been
burned but was not, and is left at the end. </span></blockquote>
But, really, in the situation of cookstoves, what the formal sector
with billions of dollars does is only of passing interest.
"Mechanical loss" is something like the smear of food remaining on a
dinner plate after a hearty meal. Just wash it off, dry the plate,
and life goes on. <br>
<br>
However, in the cookstove world, where char is INTENTIONALLY CREATED
AND SAVED, it is not a mechanical loss. It is a purposeful gain,
something that is desired. Or at least not to be used as a
penalty, as a way to make the stove appear less desirable.<br>
<br>
I have been reading Ron's replies to Xavier and to Crispin. The WBT
might be terrible, horrible, worse than no test at all, as judged by
some errors. BUT TO GIVE CREDIT FOR CHARCOAL AS "UN-USED
ENERGY" IS NOT AN ERROR, especially when the char is in such a
significant quantity and is intentionally made and gathered. <br>
<br>
Unless better evidence is provided, please do not use the
calculations involving charcoal (subtraction in the denominator) as
a major arguement against the WBT.<br>
<br>
And:<br>
<blockquote type="cite"> The question remains,
<br>
<blockquote type="cite">I would greatly appreciate some
knowledgeable comments about how THOSE OTHER TESTS handle the
issue of charcoal that is left in the stoves. Is there some
agreement between those many tests?
