This is an experiment using biomass in the KEROSENE WICK STOVE. http://e-kerbiostoveexp.blogspot.com/ (for more photographs) The stove was lit at the top using a little amount of biomass soaked in kerosene. The fine holes of 1 to 2 mm located all along the inner and outer frame are useful in achieving very good bluish flames. The flames continued for 30 to 45 minutes duration. Only at the end the performance was bad, the option was that, a lid was used to shut down safely. The fire was very high (Reasons I am not sure). If one does not have enough kerosene, and in emergency one can use the kerosene stoves too with fine wood shavings as fuel. The end product is very good biochar. I am thankful to TOM REED for explaining the functioning of a Kerosene stove, which was the motivation for doing this experiment. http://listserv.repp.org/pipermail/stoves_listserv.repp.org/2009-January...

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 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.

Dear Stovers:

I am attaching [the image above]that may be of interest to the stovers.

Here is an unsolicited commentary on our new XL WoodGas Stove, available at

Woodgas stove
along with our gasification books.

We have recently learned that BP is manufacturing a VERY similar stove
and selling them (only in India) in their equivalent of Walmart. I hear
they have already sold 100,000. Sounds like we are well on the way to
getting a "Billion Improved Stoves" out to the developing world.

If you cover the combustion air holes with aluminum flashing or sheet
metal screws the stove also makes a good gasifier.

Onward,

TOM REED
