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.
