<DIV><BR></DIV>Paul and "stoves":
<DIV><BR></DIV>
<DIV> I would add that it is very important also that all stoves
(not just char-making stoves) be rated on their production of char.</DIV>
<DIV> </DIV>
<DIV><FONT face=Arial># Why do you feel that ALL stoves should be forced to
pay for the extra expense of the testing associated with the determination of
the energy loss to the char? It is reasonable to require that stoves intended
to produce char be tested for their char producing capability, but it does not
make sense to require "Full Combustion Stoves" to be tested for
char.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV> The rating should be in kilos, percentages and energy terms.
I guess (not sure) that "fuel" means kg and its %; energy means joules
and its %. Fortunately these are all being given now by EPA and (I
think) GACC. Some wish to call anything related to char as non-existent
(consumed) - which makes no sense to me. I am not changing your
response to Kevin - only making sure that the emphasis in this discussion be
on the words "char-production" in your last sentence. </DIV>
<DIV><BR></DIV>
<DIV> Until we have a better alternative to the words "<I
style="FONT-FAMILY: Arial"> minus the energy remaining in the char" -
</I><SPAN style="FONT-FAMILY: Arial">we are stuck with it - although that
approach undervalues the char.</SPAN></DIV>
<DIV><BR></DIV>
<DIV> This is the same answer I give to Kevin who wrote earlier
today, with his and my emphasis on the word "minus":</DIV>
<DIV> </DIV>
<DIV><FONT face=Arial># It seems to me that there are two fundamentally
different "Stove Systems":</FONT></DIV>
<DIV><FONT face=Arial>1: Those that are of a design intended to minimize
the requirement for fuel input</FONT></DIV>
<DIV><FONT face=Arial>and</FONT></DIV>
<DIV><FONT face=Arial>2: Those that are of a design intended to produce char,
for other desirable purposes.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial># It thus follows that there should be two test
procedures to enable comparison of stoves within each class. Inherently a
"Full Combustion Stove" will have less fuel consumption than a stove that
inherently loses a significant portion of teh fuel energy as char.
</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial># If the "Class 1 Stoves were tested for "Fuel
Efficiency", and teh "Class 2" stoves were tested for both fuel efficiency and
the fuel energy remaining in the char, then stoves in each class could be
rated on their intended performance. Additionally, however, the fuel
efficiency of both classes could be compared, so that a Stove Buyer would know
how much more fuel he would have to purchase for a heating/cooking task, and
also, how much residual char he could expect. It strikes me as pointless and
unfair to require a Class 1 Stove manufacturer to do a char test, when his
stove is producing little or no char.</FONT></DIV>

<DIV>#1. You have added only extraneous material re naming,
China, kilns. You did not at all address the issue of treating
char-making stoves fairly.</DIV>
<DIV><BR></DIV>
<DIV>#a. Same response. You did not address the topic of
differentiating between char-making stoves. Apparently you are
happy that your money making stove in Indonesia will receive a report
that says nothing about the char produced?</DIV>
<DIV><BR></DIV>
<DIV>#b1 Same response. You have a typo "<SPAN
style="FONT-FAMILY: Calibri, sans-serif; COLOR: rgb(31,73,125); FONT-SIZE: 11pt"><I>for
a that stove</I>" </SPAN>that precludes a definitive
answer since I don't know whether to strike "a" or "the". I
continue to believe that the present approach being used by Jim
reports everything you ask for - and always has. The only new
material I know about I am delighted with - the amount of char and the
energy in the char is specifically now provided. It was always
there, but hidden. Char-making stove people couldn't be happier
with this small change in reported results.</DIV>
<DIV><SPAN

<DIV> I agree. - but for opposite
reasons than you. It undervalues the production of char.
I am willing to let it ride, since my preference is also being
shown.</DIV>

Fine, if it too can be burned as fuel. If it is not usable, it is not
fuel. Same as ash as far as that stove is concerned."
</I></SPAN>I am sorry that you don't see how
unfair this statement is to char-making stoves -- where people
(including you) can make money on the char - whether used as fuel or
put in the ground. You are taking income away from the poorest
with your stance.</DIV>

You are (I think) the only one saying this should be the rule.
Certainly no-one who thinks making char in a stove is better
economically and environmentally - regardless of where it ends up.
Of course for climate reasons I want it to go in the ground,
but I started on this topic in the early 1990s just to save
trees. Char-making stoves can do both, but since char-makig
stoves are more efficient and cleaner, char-using stoves are on their
way out.</DIV>

you are in the char making business, you still have to consider how
many cubic metres of trees are needed each day. That is the raw fuel
consumption of the char making kiln. The char produced is not a raw
fuel efficiency, it is the output efficiency of the char making
process. No problem.<O:P></O:P></SPAN></DIV>

Under a) - I repeat my original claim - you have no test in

char is there, it has not been "consumed".<O:P></O:P></DIV></DIV>

you can read the above again if you like. If there is char
remaining<SPAN class=Apple-converted-space> </SPAN><I>that is
not fuel for the stove from which it came</I>, it comes from fuel
which the stove consumed. Word it as you like. I thought you would
be asking for a report on the char production efficiency with a
rating on the energy content per kg and the % volatiles. That would
make sense if you wanted to sell it for income. I am hoping to do
exactly that in an area of Indonesia where there are many candle nut
shells. It makes really good charcoal fuel when burned in a TLUD
which people can sell for income.<O:P></O:P></SPAN></DIV>

assessing the fuel consumption of the TLUD that makes that char, we
will get the mass of fuel consumed per cycle, the energy content and
rate it accordingly. Another stove that burns the same fuel and
cooks the same amount and produces no char will consume a lot less
raw material. All we are doing is reporting how much the stove
consume per cycle.<O:P></O:P></SPAN></DIV>

direct cause is that the more char produced, the less fuel was

the WBT was changed." </SPAN></I>If char
exists, the claim of less fuel is "clearly true", not
"<I>clearly untrue". <SPAN

style="FONT-FAMILY: Calibri, sans-serif; COLOR: rgb(31,73,125); FONT-SIZE: 11pt">My
claim is related to the amount of raw biomass needed to be put into
the stove each time it is used. Your claim is to view the char
remaining as fuel. This may or may not be true for a particular
stove. If that char is fuel for a that stove, then the char can be
credited as unburned fuel. The point is to tell the prospective
buyer what the raw fuel consumption is.<O:P></O:P></SPAN></DIV>

the use of the formula A/(B-C) goes back at least to VITA days
and is in there today. On this main point under dispute, the
WBT was NOT changed (thank goodness). Or if I am wrong, please
give a cite.<O:P></O:P></DIV></DIV>

style="FONT-FAMILY: Calibri, sans-serif; COLOR: rgb(31,73,125); FONT-SIZE: 11pt">Yes
it does go back that far and it has been misleading people ever
since it was introduced. It was written on the basis that the
desired measurement was<SPAN
class=Apple-converted-space> </SPAN><I>not</I><SPAN
class=Apple-converted-space> </SPAN>the raw fuel consumed each
cycle, but the efficiency with which the heat was developed in the
fire and transferred to the pot. That is why it was called (in those
tests) the ‘heat transfer efficiency’. It isn’t really the
heat transfer efficiency, but it was given that name. The heat
transfer efficiency is a useful number for stove designers. When
making changes like pot to stove clearance the number will change.
But it is not and never was the fuel consumption figure, even for
the fry fuel consumption, because the consumption depends on what
happens to the fuel remaining. If it is long sticks that can be
burned tomorrow, fine, it is unburned fuel. Char? Fine, if it too
can be burned as fuel. If it is not usable, it is not fuel. Same as
ash as far as that stove is concerned.<O:P></O:P></SPAN></DIV>

WBT was changed and that was the major point of Jim’s recent webinar
to which you posed a number of questions and which he answered
repeatedly. I am again answering that same question. The fuel
consumption considers whether or not the remaining fuel is fuel for
that same stove. If it is not, it shall be considered
consumed.<O:P></O:P></SPAN></DIV>
