The comment below from Brian to one Listserv merits being sent to
the Stoves Listserv and Biocharstoves Listserv. Brian's comments
make a lot of sense. Let's discuss further and see if some
"implementation" can result. <br>
<br>
I hope that Ron will filter and coordinate any such discussions
because there are numerous listservs to which the messages need to
be circulated at least occasionally. There should be assistance
from the rest of us, especially if implementation is to occur.<br>

<div>Ron,</div>
<div> </div>
<div>I don’t see a problem with reporting the higher
efficiency values as long as it’s made clear what is
included in that number. As an example, combined heat
and power (CHP) plants typically report high
efficiencies because they are factoring in the energy
from the heat plus the energy from the electricity,
but the name implies they are capturing both. A char
making stove that is also heating water is essentially
a miniature CHP plant if you think of the char as the
“power’' output, but it would need to be labeled as
such. It’s a matter of semantics, but if a unit is
marketed as a char maker or a stove then the higher
efficiency numbers might be misleading. If it’s
marketed as or intended to be a combined heat and char
maker (CHC stove?) then the higher number makes sense.</div>

<div>Dear Ron,
<div> </div>
<div>If your task is to make char your
calculations is dry weight of fuel IN and
weight of char (DAF) OUT. Boiling water is
just something to do so you can have a cup
of tea while you wait. </div>
<div> </div>
<div>If your task is boiling water and you
are left with char you have a byproduct to
add to your garden. </div>
<div> </div>
<div>If you want both I suggest you place an
importance on each (percentage of
importance) for the span of a year or
season. Then with each run you keep track
of the char produced and water boiled and
try to achieve your percentage ratio. At
the end of the year you may need to just
boil off some water to get more char or
have left over char you don’t know what to
do with. </div>

<div><span class="Apple-tab-span" style="WHITE-SPACE: pre;"></span>But
I think it more proper to add
the first two efficiencies:
Effic4 = Effic1+ Effic 2 =
.333+.444 = .777 (17.7% bigger

also an honest way to look at
what is going on. Last I saw,
EPA did not add these together,
but they did report Effic 1 and
Effic 2. Sales people for
biochar and TLUDs are apt to add
them of course. We obviously

as possible.</div>

<div><span class="Apple-tab-span" style="WHITE-SPACE: pre;"></span>The
losses are 18-6-8 = 4 MJ or
4/18= 22.2% (mostly hot

claim the losses we want to
reduce are nowhere near 40% - if
you want both char and water
boiled away. 40% is the portion
of energy in the pyrolysis gases
that we failed to capture. </div>
<div> </div>
<div><span class="Apple-tab-span" style="WHITE-SPACE: pre;"></span>If
we burnt the wood (no resultant

we might expect to have a 60%
efficient stove - but no-one
measures any wood stove that
high. Why not? I don’t have a
good answer, but suspect it
might relate to how hydrogen
fits in. That is - with little
hydrogen in the char, the hot
gases are more hydrogen rich
with a pyrolysis stove. Better
heat transfer with more
hydrogen? A hotter flame? Or
is the effect due to oxygen -
which also is a lower percentage
in char than in wood? Or both?</div>

I know nothing about the

Could you elaborate?<br>
Is the Jetter/EPA total

preferred methodology as a <i>next

(Yes, I am quite out of

As I know you
know, there is
more than one
way to report
the impact of
charcoal
production in
stove
comparisons.
Examples
coming.</div>

I could not

I intend to

you have

Please
congratulate
her as well.</div>

<div

style="FONT-SIZE:
10.5pt;">This
review
intended to
collect and
collate the
information
related to
cookstove
testing
methodologies
applied in lab
and field
conditions and
their output
in the form of
energy and
emission
parameters.
The important
information
related to
progression of
cookstove
testing
techniques was
segregated in
order to
understand the
relationships
in different
indicators of
cookstove
performance
and to
understand the
sources of
uncertainty in
emission data.
The major
research issue
that has been
dwelt upon in
the recent
literature is
the
establishment
of
relationship
between lab
and field
results of
cookstove
performance.
It is observed
that
controlled
cooking test
and kitchen
performance
test are the
two field
based tests
which provide
a better
picture of a
particular
cookstove
performance as
it involves
the user
perspective.
Misrepresentation
of actual
cookstove
performance
based on
laboratory
based testing
puts the
present
standard
protocols in
question.
Solutions have
been put
forward by
some research
studies;
however a
validation is
needed through
multiple
scientific
investigations
conducted at
various
temporal and
spatial
scales. It has
been observed
that cookstove
testing
methodologies
are still in
their nascent
stage compared
to the
research that
has already
been conducted
for other
sources where
biomass
combustion
emissions have
studied
thoroughly.
Still the
shift in focus
of upcoming
research
studies
towards field
based
integrated
cookstove
testing
methodologies
has the
potential to
drive future
cookstove
research in
the new
direction.</span></div>
