How to Make Charcoal
Robert Flanagan, SAFFE, January 30, 2008

I've just been playing around with my natural draft stove to see how easy it would be to use it for cooking and making charcoal http://www.youtube.com/watch?v=sZZDtXOiGLE .
I fed some extra fuel in the side so show the pyrolysis reaction taking place.

Vesto +_ Switchgrass Pellets Crispin Pemberton-Pigott, New Dawn Engineering, Roger Samson, REAP Canada, January 5,2008 Densified Canadian switchgrass pellets were burned in a VESTO (New Dawn Engineering) stove in the gasification mode. Dear Grass Burners Roger Samson was here today with Stephanie and he brought along a Mayon Turbo stove with rice husks and a big bag of switchgrass pellets. We tried this 'fuel of the future' in the Vesto which first required putting a small sheet of newspaper at the bottom to keep the little pellets in, and second perforating the sheet to let in a least a small amount of primary air. It was packed pretty tightly. The pellets are about 15 MJ per litre. We lit it on top with a small wood fire and it got going nicely. It burned very much like a Vesto with the 'gasifier mode' engaged meaning that it ran with very little primary air getting through and a floating bed of flame perhaps 7 cm above the fuel. Very pretty. The CO/CO2 ratio was stable at 2% and had no odour or visible smoke. I will get some picture posted and a movie with a description by Roger. The flamefront was shallow, as Alex describes with wood pellets. Nothing really to add - it burned completely and gave off lots of heat. Regards Crispin

Hybrid Stove Making Charcoal (YouTube)
Lanny Hensoni, July 26, 2007

Biomass cooking stove burns wood to charcoal and saves the charcoal. One pound of wood cooks 6 kilos of rice and makes 65 grams of char.

Hybrid Stove Burning Bamboo Pan Cooking

See: http://www.youtube.com/watch?v=oIsNZHSkX8k

Here is another 3 min video of the Hybrid Stove burning bamboo chips and pan cooking eggs.
Bamboo chips burns well in the Side Supply Burner but the pan only reached medium heat.
The heat from the burner seems to be diffusing and bypassing the pan. Enough heat is being generated by the burner but the pan module lacks focus.
Suggestions to fix pan module?
