<div>Dear Ed,<br>
<br>
I also would like the drawings and photos. And even better for
everyone, please send those items to Erin Rasmussen who can put
the items on the Internet at the stoves website and at the biochar
website.<br>
<br>
I think your listed reasons for having a Rocket inside instead of
the standard Anila simple burning area are excellent.<br>
<br>
I have a few questions:<br>
1. to empty out the biochar, do you have a clean way that can be
done inside the home? Or is it still best to take something
(describe what it is) to an appropriate area?<br>
<br>
2. And can you do (or envision doing) an arrangement for
"reloading" the Anila part of the stove? That is, exchanging some
container of biochar for a container with biomass to be
pyrolyzed? And has anyone done this? The closest I know of
something like this is the people who put containers of biomass
(including outlets for the gases) directly into fireplaces or
campfires. Those containers can be continually reused as long as
the exterior fire is burning.<br>
<br>
3. Do you have a way to cut off the air to the Rocket sector when
the pyrolysis of the retort (Anila) is supplying plenty of gases
to be burned? This would seem to be a logical capability to
have.<br>
<br>
4. Your system is for home heat and hot water also. Please
describe that for us. (and in what climate zone do you live?)<br>
<br>
5. I hope that the "mainly discouraging responses" did not come
from TLUD advocates. What you are proposing could be done ABOVE
a TLUD as the initial source of heat (but not with the retort
around the TLUD reactor because it is only hot at the top at the
beginning, and the retort needs heat on its full length right
away.)<br>
<br>
6. IMAGINE 3 or more enclosed Anila-style crescent-shaped
(removable) retort chambers that form a central "chimney"
(actually it is a riser). Get it started with heat from a Rocket
or TLUD or simple fire and use the off-gases to continue the
pyrolysis. BUT have the 3 or more chamber at different stages of
the retort process: drying out the fuel (up to about 120 C),
torification up to about 300 C, pyrolysis up as high as the retort
can be operated. I am suggesting that the combustion of the
off-gases from ONE of the chambers might be sufficient to take the
other two to higher temperatures. And then when the first one
has completed its pyrolysis, empty it and put it (or another one)
in its place, keeping the sequence going on and on and on. One
advantage is that the overlapping time periods of the retorts
result in continual fire with "batch-length" time periods for
attention instead of the frequency of attending to the fuel in
Rocket stoves. If anyone tries this, please inform us, even
if the results are not very good.<br>
<br>
Keep up the good work. It is experimenters like you who are
reporting new capabilities.<br>
<br>

Trent,<br>
<br>
Yes I have built stoves with the retort around the
combustion area of a rocket type stove. These stoves can
be seen as just another variation of anila stoves but in
practice they are a vast improvement;<br>
1, they burn more cleanly than standard anila stoves
because you can control the amount of air entering the
combustion zone,<br>
2, being front lit (rather than top lit) it is easy to
add hoppers so these stoves can be brought indoors under
a flue pipe as they do not need to be moved to fill,
light or empty the biochar.<br>
3, you can continue to burn them as rocket stoves once a
batch of char has been made<br>
4, in my experience it is much more efficient to produce
biochar with combustion inside rather than surrounding
the retort.<br>
5, combustion inside rather than surrounding the r
capture.<br>
<br>
I run a small market garden and for over 3 years I have
produced a steady stream of biochar (around 5kg a day in
the winter months) from these stoves.<br>
<br>
I have no domestic energy bills for heat, hot water or
cooking. Other people waste the heat they generate by
producing biochar.<br>
<br>
<div><span>For some reason I have received mainly
discouraging responses from the 'experts' in biochar
stove fields. (See the discussion of 'biochar rocket
stoves' in the yahoo groups stoves list.) I often
find that 'experts' have a reputation to maintain
but to dismiss a good stove design is their loss.</span></div>
