create something with a feature that is not otherwise possible. So far I have not seen one, but perhaps will eventually.

<div>When will folks ever learn? I get such good results I am surprised that folks have not tried to replicate them. It is shame that folks still use concentrator rings.</div>
<div><br>
</div>
<div>Have you seen my trash can stove? It is actually one of my three can TLUDs in a 33 gallon Trash can which acts as a safety device as well as a way to capture some of the heat lost horizontally from the TLUD to do some preheating of BOTH the primary and
secondary air.</div>
<div><br>
</div>
<div>Works like a dream. Very repeatable and very predictable.</div>

<div>Sir,</div>

<div>I have long since abandoned concentrator rings. I find I get much better results with a flame retention plate above the fuel bed and just below the secondary air supply. I combine this with three deflection washers a bit above the secondary air intake.
This creates a "combustion chamber". The flames remain mostly in the chamber - very dynamic and quite noisy. I cook over the column of hot gases raising up the draft pipe. When properly tuned, there is essentially zero soot deposited on the pots. This
indicates a clean burn.</div>
<div><br>
</div>
<div>BTW, Students at Dartmouth College have created a fan powered TLUD with a top plate such as yours. It can use saw dust as a feedstock.<br>
<br>

<div dir="ltr">Hi stovers, <br>
<br>
I never liked (for cooking purposes) the single-thick flame that comes out of the concentrator ring that use most of the TLUD's designs, because you get a narrow over-heated spot in the bottom of the cooking pot, and in a result of that, you don't get a good
heat distribution in the pot.<br>
<br>
I made a new "diffuser" burner, which gives a circular flame area, instead of a single one.<br>

Anyone knows any other works on this aspect?<br>
