<DIV><FONT size=2 face=Arial>Crispin,</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Attached is the document which introduces the
turn-down methods I have been looking at. </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>My comparison is that all three stoves, the Peco
Pe, Vesto, and Prime stove introduce air lower in the reactor from holes in the
reactor wall, directing air at the char. The Method 2 arrangment
introduces the air high in the reactor, just under (2.5 cm) the secondary air
entrance. This air combusts wood gas forming a pilot flame just under the
secondary flame. The way it works is that the pilot flame supports the
secondary flame, keeping it hot and maintaining flame presence which enables the
secondary flame to survive turn-down. The functions of the two methods,
blowing air on the char vs. forming this pilot flame are very
different. Method 2 at first seems unlikely to work. When I
first saw it, I was surprised and upset because I could not see how it
could work. It happened by chance. I was testing Method 1
to see what was the best sequence for adjusting the three controls to lower the
flame. I tried several sequences. Then I tried opening the secondary
air control and then reducing the early secondary air to form a small flame
(this small flame acted as the pilot flame). I reduced the
primary air. To my surprise and shock, the secondary flame reduced to a
strong medium sized flame. Usually the secondary flame becomes
unstable and produces smoke before an early secondary flame appears at the
char. I reduced the primary further and the secondary flame reduced even
further, still no smoke. I kept reducing it until the small secondary
flame finally became unstable. I was very upset because I had been
working on Method 1, producing an early secondary flame at the char for
over a year and here was a stable and small secondary flame. I felt like
my work was a waste if the secondary flame can be stable during turn-down.
In time I realized that this was a seperate method for turn-down, and it
became Method 2. Methods 3 and 4 were found later in a similar manner, by
chance while doing tests on Method 1. I did not predict or plan these
methods, I only found them by chance. I found Method 1 by chance also,
while doing tests with spinning the air forming a vortex, and I noted the
spinning air sometimes descended into the stove and kept the flame alive even
when I shut the primary air off. I saw that the flame could be kept alive
with air from above and this led to Method 1.</FONT></DIV>

<P class=MsoNormal><SPAN
style="FONT-FAMILY: 'Calibri','sans-serif'; COLOR: #1f497d; FONT-SIZE: 11pt; mso-fareast-language: EN-US">The
layout and function as you describe do not apply to the Vesto so I was
wondering what you mean by a ‘pilot flame’. The Vesto dies have a pilot
flame with air provided by three 8mm holes quite low in the chamber, well
below the secondary air inlets. This is relevant when the bottom of the
combustion chamber is blocked in order to run in a TLUD gasification mode.
Normally that is blocked with a circle of newspaper with a few knife slits in
it.<o:p></o:p></SPAN></P>

style="FONT-FAMILY: 'Calibri','sans-serif'; COLOR: #1f497d; FONT-SIZE: 11pt; mso-fareast-language: EN-US"><o:p> </o:p></SPAN></P>
<P class=MsoNormal><SPAN
style="FONT-FAMILY: 'Calibri','sans-serif'; COLOR: #1f497d; FONT-SIZE: 11pt; mso-fareast-language: EN-US">The
pilot flame ensures that wood can be charcoaled and burned controllably, or
pellets (packed bed function) can be pyrolysed and then the char burned. This
function enables the user to load quite a lot of fuel into the stove but burn
it slowly – far slower than an ‘open fire’ would be able to.

however not a Method 2 stove. It more resembles a Vesto or Peco
Pe. The early secondary air inlets are too low to provide an efficient
pilot flame. They were clearly designed to direct air at the char and
show no knowledge of the interaction of Method 2 type pilot flames with
the secondary flame. If the lower holes were eliminated and replaced
with holes directly below (2 to 2.5 cm) the secondary inlets, then it would be
a Method 2 stove. Possibly the stove would then get a 3.1 turn down
ratio instead of a 2.1 turn down ratio. Please examine my document again
to see the difference.</SPAN><SPAN

<P style="BACKGROUND: white" class=MsoNormal><SPAN
style="FONT-FAMILY: 'Calibri','sans-serif'; COLOR: #1f497d">I agree with
your analysis. There is a lot of merit in keeping the secondary flame in
close proximity to the top of the fuel bed. The most important is that the
secondary flame is harder to put out with a slight breeze (because it
relights). The second is that when the primary air is turned down to
control the power, the secondary flame is able to remain hot enough to
stay alight. Combined with external, down-drafting secondary air
preheating (not like the Peko Pe) one can maintain the secondary air feed
ration under different primary air
conditions. <o:p></o:p></SPAN></P></DIV>

<P style="BACKGROUND: white" class=MsoNormal><SPAN
style="FONT-FAMILY: 'Calibri','sans-serif'; COLOR: #1f497d">Read and heed!
TLUD's are not succeeding in meeting the turndown ratios required by
ordinary cooking. To burn clean at different burn rates, whatever the
fuel, you have to control both the primary and secondary air
flows. <o:p></o:p></SPAN></P></DIV>

<DIV>
<P style="BACKGROUND: white" class=MsoNormal><SPAN
style="FONT-FAMILY: 'Calibri','sans-serif'; COLOR: #1f497d">While a
'double controller' can work, turning the secondary air down at exactly
the same time as the primary leads to a 2-3 minute period of very high PM
and or CO and VOC's because of the retained heat in the fuel bed and stove
body. This is worse if the combustion chamber is ceramic or cast
iron. <o:p></o:p></SPAN></P></DIV>

<DIV>
<P style="BACKGROUND: white" class=MsoNormal><SPAN
style="FONT-FAMILY: 'Calibri','sans-serif'; COLOR: #1f497d">If the
secondary air feed it an automatic, buoyancy-driven ýsupply, it will draw
in additional air as required during the cooling-off period. This explains
the strange layout of the air supply in a Vesto Stove which tried to
address the problems inherent in David Hancock's (very advanced at the
time) 1984 Tsotso Stove (which is still in
production). <o:p></o:p></SPAN></P></DIV>

the 4 holes concept in the middle of the combustion chamber can also helps
to maintain a slow power consumption. When the pyrolysis front reach the

charcoal, adding heat to also support the
