Dear Frank Many thanks for you report. Can I ask that you observe something: I have noticed many times that if the number of particles occupying the space (width/diameter) of the container is less than 5 (bigger particles) things do no go well.
So I have this idea that the particle diameter and in a way the space between them (recognizing that flakes are different from balls) is a major determinant of the quality of the burn. I have settled on the number 6. If the particle size is larger than 1/6th of the diameter, things are not going to work well. This applies to TLUD and downdraft stoves. In order to burn large chunks in a small stove, a completely different approach is needed, basically making a refuellable retort which is described by your suggestion. It seems the Dia/PSize is fundamental for many types of simple burner.
