Any emission test results?</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>b. You say below “till the charcoal burning”. Assuming you have a char-making stove, does this mean that the vortex ceases when the pyrolysis front has reached the bottom?</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>c. Could this vortex be achieved with natural draft?</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>d. Assuming there my be some patent and IT issues here - what more can you say about air hole placement that might encourage others?</div><div class=""><br class=""></div><div class=""> 2. We have not yet heard on why an earlier TLUD stove in at least one place in Indonesia had achieved a number-one ranking. Did it have anything to do with the produced char being used as biochar? Is this new “vortex flame” stove headed for the same market?</div><div class=""><br class=""></div><div class="">Ron</div><div class=""><br class=""></div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Feb 19, 2016, at 6:50 PM, Muhammad Nurhuda <<a href="mailto:mnurhuda.ub@gmail.com" class="">mnurhuda.ub@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><div class=""><div class="">Stovers,<br class=""><br class=""></div>Finally we have been able to develop forced draft TLUD stoves with vortex combustion, where the flame is pushed down and circulating around, creating strong ring vortex.
