ROCKET STOVE FOR 100, 200, 300 Liter Pots
The 100L stove has a high power of 10.6kw. Using the PHU water boiling test resulted in 49.5 %. The stove takes 52 min to boil 75L of water. There is a 1cm gap between the large pot and the skirt made from brick. The insulated fire box is 8 inches square and 20 inches tall. A tile shelf supports wood in the feed magazine...
The cost is between $50 - 150 US depending on finish and quality of brick . It takes 2 days to build. Also available are a 200L and 300L brick version that GTZ is buiilding this week in Uganda. Kawere Muhammad is selling a metal version for 1, 2, and 300 L which is Insulated with cut pumice block.
Note the full rolling boil with a couple of sticks in the combustion chamber and no visible smoke with dry (but also true for wet) wood . The version shown does not have a chimney . The same stove can be easily fitted with a chimney which can reduce the PHU score.
I have CAD and step by step photos of the stove but I'm still trying to turn them into a PDF so that I can send them out to everyone.
PLANCHA STYLE BREAD OVEN STOVE
17 kg of bread with 5 kg of wood. This was a considerable reduction in wood consumption as compared to the traditional wood fired bread oven which consumed 200 kg to bake the same quantity of bread !
