Low-cost Wood-gas (Gasifier) stove - BEST STOVE

Low-cost portable Wood-gas (Gasifier) stove - BEST STOVE

A low-cost portable Wood-gas stove has been developed based on the Garlington’s portable gasifier model. It is top-lit and the draft is upwards. A small tin can of 3.5 inches diameter and 5 inches height is used for making the Wood-gas stove. For grate an aluminum wire is used at the bottom (even iron wire or nails can be used). Primary and secondary air slits are punctured into the tin to make the stove. A tin sheet or bricks or mud and stones can be used for the skirt and fire place.

For fuel one inch length small pencil size sticks (pruned twigs) or shavings and chips of wood from a carpenter’s workshop can be used. This stove burns for about 8 minutes with the wood-gas generated and later on the resultant charcoal burns for next 5 to 8 minutes giving sufficient heat for boiling one liter of milk or one person can take bath with the boiled water.

Price : Rupees. 2/- (Rupees two only)
Time for making it : 20 to 30 minutes
Efficiency : Highly efficient as compared to rocket stove.

After the success of this model, I have designed a clay version of the same. These are made up of clay+ sand (quartz / silica) + cowdung + ash, each one costing only Rs. 10/- or 0.25 USD.

This stove has the following advantages:
Requires only small wood pieces – saves trees
Batch feeding – lit and forget
Low cost any one can make it and use
Light weight - highly portable

Note: Preferably should be used in good ventilation conditions.

I am very impressed by this effort. This is mighty eco friendly exercise which needs to be commercially marketed in rural areas. I am a bit worried about the particulate waste which this device should be able to handle without getting into wrong places.

What are the sticks showing at the bottom of both the clay and the tin can stoves?

To jimmy:
The drawing and photos on
http://e-woodgasstove.blogspot.com/
are pretty clear. The "skirt" in the drawing appears to be a "partial cylinder" of sufficient weight/strength to support the cooking pan. The smaller can inside the skirt is the coffee-can stove.

To steve:
I at first wondered about the "sticks" at the bottom of the coffee can in one of the photos, and thought they might be "tubes" to supply primary air. However, I believe they are merely "scrap" wire interlaced through holes in the bottom to form the "grate" to support the fuel (as the drawing notes).

Interested in Gasification stoves. Can we use bigger firewood in the stove, say 2 to 4 inches diameter and longer lengths.

Please continue with your designing of efficient stoves for people. Because appropriate technology is about people, making it different from that sustainable technology model of long term impacts and ignoring that individual. With great talent being shown in the area of, promotion because learning both what people desire and are willing to pay for it is marketing research.
=====================================================================================

And this marketing research part, requires finding and developing relationships with people on the ground. So continue with that rare skill of visiting with people. For that creating of a less waste oriented future, where items other than trees such as waste wood from carpentry can be used for common tasks.
