Paul O. raises an excellent point. I think that the moderate complexity of the Belonio hole pattern and secondary air inlet (contrasted to simple concentrator hole) has kept me and probably most others from experimenting with it. Perhaps we incorrectly associated it too much with the forced air (Fan Assisted = FA) aspects of Belonio's rice husk gasifiers.<br>
<br>
Very little is known about the tops of TLUDs except that some amount of constriction is needed to force the mixing of air and gases.<br>
<br>
I hope that the engineers (such as Bob Fairchild and student engineers) and others who are now working on TLUD stove issues will seriously consider the Belonio top and related enhancers of combustion of the gases.<br>

<br>
You say:<br>
*# OK!! A 50% reduction in boiling time is very significant.<br>
What can you now tell us that will enable us to apply it to other stoves<br>
and combustion conditions?*<br>
<br>
I once did an experiment in which I made the 150 Belonio about half its<br>
original height.<br>
I then filled it with chunks of wood and put a Belonio burner on top.<br>
This was a natural draft unit without a fan.<br>
This is what it looked like:<br>

But looking back on this, I see that there were so many problems with this<br>
burner,<br>
even aside from the fact that it had no burner housing.<br>
<br>
You raise an interesting question, though, which has always led me to wonder<br>
why the Belonio burner hole pattern was not adopted on natural draft units.<br>
If a burner housing were added, I think the unit I experimented with would<br>
work much better.<br>
The central problem that I see with a natural draft unit is an uneven<br>
upward flow of primary air.<br>
At times too much CO2 is created, and some burner holes lose their flames.<br>
Also I would imagine that the inlet of primary air has to be strictly<br>
control to get a consistent outlet of gas at the burner.<br>
<br>
A natural draft TLUD is very complicated,<br>
and I truly marvel at those who get them to work on such a broad variety<br>
of fuels.<br>
