[Stoves] Fuel Management - Bamboo Sawdust

[Tony Vovers]

Many thanks for the ideas and observations

The treatment is a borax salt treatment that is used to make the material
much less enjoyable by critters. My understanding is that it is relatively
benign, but maybe not something to use for char production.
These combustors I imagine produce only ash so this could be an advantage.

Looks like I have some homework.
