[Stoves] diy TLUD flame

[Jonathan P Gill]

Tom, 

As I have show in previous posts, the use of a gap for secondary air, NOT holes, combined with the use of washers above the gap as deflectors, works well to increase turbulence/mixing of the air and fuel as well as to increase residence time in the combustion zone. This tends to keep the flame mostly in the  TLUD and prevent long flame tails from streaming out of the TLUD. Long flame tails tend to also carry out a significant amount of particulate matter and should be avoided. 

If your cooking pots turn black with soot, you have incomplete combustion, poor air fuel mixing, and insufficient residence time.

For more, see my post on Pyro-Grilling on www.greaterdemocracy.org

Cheers,

Jock
