[Stoves] List of woods for TLUDs?

Sat Apr 29 03:29:05 CDT 2017

AD and list:

	1.  I agree with your first sentence below. Additionally, we should mention non-woody biomass - especially rice husks, which have extremely low density.   The only low density fuel I never was able to use in a TLUD was dung.  I consider this another major plus for TLUDs.

	2.  I differ on your second sentence.  I think a TLUD is to be preferred for all forms of biomass.

I had some other ideas using air flowing artificial ’smoke’ but to lack of interest never followed through.
