[Stoves] diy TLUD flame

[Jock Gill]

Tom,

All I can say is that my deflectors work like gang busters.  Not sure why the  idea is not more widely used.  I use three washers.  Maybe I just got lucky, but deflectors above the secondary air gap, with a draft enhancer the same as the diameter of the TLUD, is the solution I have standardized on.  I use two cans of the same size: one for the TLUD and one for draft.

Cheers,

Jock

Otherwise they can float along side by side without ever mixing, or just mixing poorly. John and Flip Anderson tried using ceramic plates to improve mixing and flow in a rocket stove. It seemed to work but after considerable testing they abandoned it.

This technique generally keeps the flames within the TLUD.  Long flames coming out of a tLud are going to carry a lot of particulate matter out with them. Fan not required.
