<div dir="ltr"><div>Hello stovers;</div><div><br></div><div>This morning I woke up with an idea, and decided to give it a try. It worked out quite well. I put a inverted, conical ring on the top of a natural draft, top-lit updraft (ND-TLUD) reactor, and set a chimney on top of that so that secondary air could get in between the bottom of the chimney and the conical ring. The rig is a bit like putting a cone kiln on the top of a TLUD. The best burner had walls of the cone at an angle 60° from horizontal. Secondary air was forced to enter the top of the TLUD in a downward direction, counter current to the direction of the pyrogas rising out of the fuel bed. The result was a turbulent flame indicative of good mixing of gases.</div>
<div><br></div><div>It is too early to say if this counter flow burner is viable, but is looks very promising. It is also very easy to manufacture. </div><div>How to get the geometry for a cone can be found here: <a href="http://zenstoves.net/PotStands-Conical.htm#MakingYourOwnCone">http://zenstoves.net/PotStands-Conical.htm#MakingYourOwnCone</a></div>
