Magh CM Woodgas Good Stove http://e-maghcm.blogspot.com/ designed recently is a very low cost TLUD stove meant for Common Man (CM). This can be produced by the local communities with less than 8 dollars (USD). Under Magh CM series I have designed many stoves / burners in the past. This stove design is one of the most acceptable stoves, as it has the options to run on forced air / natural draft. Most importantly the convenient charcoal / ash removal facility is created at the bottom, the grate can be simply lifted using a wire and immediately refilled for reuse. The additional window for secondary air in case of no power, the primary air control and the 12 V DC powered fan makes it like a geared vehicle for multiple options to control the heat / flame / updraft. Used the most commonly available oil tin can of 12 inches x 9 inches x 9 inches with a combustion chamber of 6 inches diameter and 9 inches height for the convenience of adoption for a family of 5 members cooking needs. The tin cans are easily available all over India. Posting here the pictures and the design for your valuable comments for improvement. I am thankful to all for your valuable suggestions in the past. This is the 30th Good Stove design of Avan and Magh series since last 4 years of my research and design. Happy to share that the people who have seen this stove have paid money in advance for having these Stoves. For more pictures and info see http://e-maghcm.blogspot.com/ and http://picasaweb.google.com/saibhaskar.gsbc

This is the prototype of Magh series "Magh Utham Woodgas Burner". http://e-maghutham.blogspot.com/ This is a natural draft burner (forced air is optional). Low cost, low weight, easy of operation, easy to collect the biochar by rotating the combustion frame and easy to reload it. As it is can be used for boilers / institutional stoves / domestic cooking / etc. The performance is good. There could be some more improvements in its design to increase its performance. For details and photographs see the link http://e-maghutham.blogspot.com/ . The term "Utham" refers to "Best" which is part of the name of Prof. K. Purushotham Reddy a very well known environmentalist in India.

Magh CM-II http://e-maghcm-ii.blogspot.com/ natural draft woodgas stove http://e-maghcm-ii.blogspot.com/, it is a very low-cost stove for heating and generating charcoal. It can also be described as a mini-charcoal making metal kiln. Instead of incinerating biomass generated from home gardens / any other dry combustible material generated as household waste usually throw into the garbage bins, can be used here. The leaf litter, dry twigs / sticks, chips of wood, wood shavings, etc., are very much suitable.

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.

I fed some extra fuel in the side to show the pyrolysis reaction taking place.

The author, Gary Gilmore, explains how he designed a charcoal retort from 55 gallon drums. This is a smoke free design also the flare could be put to use.

Hybrid Stove Making Charcoal (YouTube)

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

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?
