[Stoves] The Art of Using Grass Bundles in TLUD Stoves

[Anand Karve]

Dear Martin,
we did a lot of experiments with the sawdust stove developed by my
daughter. It turned out that the particle size of saw dust palyed a
crucial role in its working. When tested with straw or leaves of trees
as fuel, it produced copious smoke. We got a smokeless, near-blue
flame only when we packed it with saw dust of a relatively small
particle size.
Yours
A.D.Karve
