Fuel Briquette Burning at Stoves Camp 2008

This prototype was to check the hole of the briquette and how gasification can do a nice job. As said, starting the fire with few small sticks and then after preheating the chamber, briquettes ignite by themselves and burn throughly. You can help flames with having a stick in the hole while burning. I really liked how the briquette retained its shape after it burned out, so you could still push the next one it without preventing the draft..

But the briquette burned with the surface lit from the combustion chamber, as Larry predicted. You could literally walk away of the stove with the consistent flame going on all the time (I guess the briquettes were good quality :) The air inflow was only through the hole of the briquette.

Funny was, that even when one briquette burned out, the next one ignited and the airflow continued through the hole of the first briquette.

Mdula: A DIY Mud Cooking Stove
Rok Oblak, August 2008

MdulaMdula

Mdula or Modular Mbaula (stove) is a design project aiming to simplify the construction of an efficient household mud cooking stove for extreme rural areas. It is based on a Do-It-Yourself (DIY) construction techique using a simple wooden mold.

Rok Oblak has started a blog on the development of the Mdula at:

Ecosur: Holey Sawdust Briquettes
Fernando Martirena, September 2003

Here are pictures of our recent development in the field of clay bound briquettes. We have -after a hint from the stoves list, shifted to a holey sawdust briquette which burns far better than our previous versions. We have also re-engineered the machine, which now is more productive...
