I plodded through the bioenergylists archives looking for sawdust stove discussions a few months ago in the hopes of finding information the would be helpful for natural draft rice husk stoves. I believe the most fruitful thing to search for is "WWII sawdust stove"
I only found one class of design: an outer cylinder and inner tube. You light the sawdust from the bottom and the inner tube draws air to sustain the combustion. It is possible to just use a stick and pack the sawdust instead. There are a few stoves in A Woodstove Compendium<http://www.appropedia.org/A_Woodstove_Compendium>that operate on this principle. I had some Bolivians draw me such a design when they visited our group in Atlanta. Apparently they are rather commonly used for drying/curing operations. It's not hard at all to get them going. In fact, we melted a few of our sheet metal cylinders because they would go out of control. Made some nice looking sculptures as a result. Has anyone had different experiences? I was not able to find anything recent on sawdust (and other fine bio-material) combustion in cook stoves. Marc Paré B.S.
