Dear Mark Thanks very much for the "summarizing explanation."
It almost seems that the Sawdust Stove is simply a great big forerunner of Richard Stanley's Holey Briquette, and Tom Reed's TLUD. Thanks also for the Wood Stove Compendium Site Reference. Very interesting indeed!

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 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.

Would you be kind enough to describe how the stove is intended to work, for the benefit of us who don't read German? Thanks!

Cover-sheet with the description for the intention of the insert (“Einsatz”) http://www.collection-appareils.fr/brevet/Kaftanski/DE423728/page1.pdf Drawings with description: http://www.collection-appareils.fr/brevet/Kaftanski/DE423728/page2.pdf Sometimes progress can happen by altering old ideas. Let the stovers know if you would like to modernize it for whatever purpose. Best wishes for the New Year!
