<p class="MsoNormal"><span style="color:windowtext;mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext;mso-fareast-language:EN-US">I not only provided the example from a chemical balance point of view for the auto-catalysis case, I provided the example of auto-pyrolysis.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext;mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext;mso-fareast-language:EN-US">What is the point I ‘glided past’?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext">></span>You conveniently glide past the fact that what we are really interested in on this Stoves Listserv IS about stoves that are of small scale.<br>
<br>
<span style="color:windowtext"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext">></span>What you provide below is quite idealized, in perfect condition, shown in theory and a chemical formula.
<span style="color:windowtext"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext">I provided both the theoretical conditions and the practical conditions encountered on the scale at which small stoves operate.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext">></span>Maybe that way it might be confirmed by a chemist as being true, but it certainly is of minimal relevance to solving the cookstove problems of impoverished people.
<br>
<br>
<span style="color:windowtext"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext">It is true and it is part of the understanding of what is going on.<o:p></o:p></span></p>
<p class="MsoNormal"><br>
<span style="color:windowtext">></span>The term "splitting hairs" comes to mind.
<span style="color:windowtext"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext">Lighten up. If you want to discuss the foundations of the process you are promoting it is correct to know what happens and when.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext">>I looked at what you wrote, but I certainly did not seriously study it. You comments might be rignt, but your comments are of minimal or no relevance.

<p class="MsoNormal"><span style="color:windowtext"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext">You are free to ignore all of it. I have tried as comprehensively as possible to support the statement that biomass can auto-pyrolyse without the addition of air, and that this phenomenon can be demonstrated
using a thermogravimetric analyser – charts provided – showing the temperature at which it takes place.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext">The reactions are exothermic, and provide enough heat to continue the pyrolysis indefinitely
<i>without air</i> until the fuel is all reacted. The result is char plus pyrolysis gases.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext">It is possible to build a device that will do this from tin cans. I think it is unhelpful to keep shooting the messenger.
