[Stoves] "Stealth fires" and Wendelbo and TLUD history

[Jock Gill]

All, 

I am curious that there is no mention of TLUD designs that have developed alternatives to the centralized "concentrator" approach. 



Next week I will report on a device with a 6 inch diameter with a 7 inch diameter stove pipe cap.

See also the work of Paul Olivier in Viet Nam.

In the past, I have posted on TLUD designs that user one or more solid flame retention disks rather that a  concentrating central hole.

Lots of ways to skin a cat. 

Regards, 

Jock

There is a great deal of biomass around Kampala in the form of reeds and bullrushes which served as the fuel source.
