</div><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">Could you please take a look at my attempt..... the holey roket as a char making stove. I thought i designed the holes to make a flow of secondary air in the roket stove. There are eight holes by the elbow, a little above the height of the fuel feeder. One hole is directly poking opposite the fuel feeder to reduce the stress of the high intensity flame on the stove wall (as Crispin advised me before)I made the holes to follow a co centric circle to make the secondary air twist. The stove wall is 3 cm thick and so the incoming air would go about 6 cm through. I thought this would add to the pre heating of the incoming air, to compensate for the absence of a double wall. And then to make the flame twist in the same manner as the fins of those from the designs of the recho roket would. <u></u><u></u></p>
</div><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">And so i observed that the flame twists and very clean, yellow with blue streaks shooting off from the holes. Please see the attached pdf file. <u></u><u></u></p>
</div><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">Is this already the pre heated secondary air at work? <u></u><u></u></p></div><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">
My limitation is that i do not have instruments to verify all these observations. Perhaps your opinion could help for the meantime. <u></u><u></u></p></div><div><p class="MsoNormal"><u></u> <u></u></p></div></div></div></div>
