[Stoves] Research topic: Increasing turbulence at the level of combustion of TLUD gases.

[Paul Anderson]

Jock, Crispin, and all Stovers, (James, for my website listed/tagged as 
R&D work to be done.)

As far as I know, there has not been much study of the impact of 
variations and options for increasing turbulence (using natural draft, 
not force air) at the level of the top of the TLUD fuel cylinder.   This 
is certainly a topic that merits attention and could have significant 
impact on improving stove performance.

The same TLUD stove (for purposes of need to control variables) to be 
tested with only changes to the combustion area of the pyrolysis 
gases.   And what is found to be better, then also needs to be tested on 
other TLUD designs.

However, even with rigorous observations and controls, ultimately 
emissions data will be required, and for that, equipment will be needed.

This would be a fine topic for some student group to undertake, or for a 
master's thesis, or any of the many Stovers.   I and probably several 
other Stovers would gladly facilitate/assist anyone undertaking this 
very interesting task.

I expect this is why my iCans with three washers as deflectors, in contra distinction to a "concentrator ring", burn cleaner.  The deflectors increase both turbulence and residence time in the combustion zone.  Secondary air slots also contribute to the turbulence.  At least my iCans with secondary air slots burn much cleaner than those with various holes used for secondary air.  My current system burns cleanly enough to deposit very little soot on cooking utensils or food.  They are essentially soot free.  Perhaps "soot free" should be a goal?
