Low Cost Wood Gas Stove
Dr. N. Sai Bhaskar Reddy, Hyderabad, Andhra Pradesh, India April 2006

Look at this blog of a wood gas stove developed with community participation.
A low-cost portable Woodgas stove has been developed based on the Garlington’s downdraft gasifier model stove. A small tin can of 3.5 inches diameter and 5 inches height (“Lactogen” tin can) is used for making the Wood-gas stove. For grate an aluminum wire is used at the bottom. Primary and secondary air slits are puctured into the tin to make the stove. A tin sheet or bricks or mud and stone 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 : Rs. 2/- (Rupees two only)
Time for making it : 20 to 30 minutes
Efficiency : Highly efficient as compared to rocket stove.

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.

SARAI STAINLESS STEEL STEAM COOKER

AD Karve January 2003, REV 2006

Sarai is a stainless steam steam cooker. It is a non-pressurised cooker, into which you put about 150 ml of water and then lower into it a wire cage, which holds three cookpots, one on top of another. The steam pot has a lid which is kept closed while the food is being cooked. The heat is provided by a charcoal burner, which is designed to hold just 100 g of charcoal or a single honeycomb briquette of 100 g. After the coal has caught fire, the steam pot containing the food to be cooked is placed on the stove.

The Beehive (Honeycomb) Charcoal Briquette Stove in the Khumbu Region, Nepal, Sjoerd Nienhuys (1 800 kb pdf) March 18, 2003

1.1 OBJECTIVE
The document is the result of a mission to Lukla/Mosi (8,000 ft. / 2634 m) and Khumjung (11,800 ft. / 3882 m) in the Khumbu region and contains observations about the use of the Beehive charcoal briquette stove for cooking and space heating. The Beehive charcoal briquette stove has the potential to become a practical source of renewable energy (RE) for domestic use, hotel owners and trekkers in high altitude camping grounds. Currently large amounts of kerosene is being brought into the region to satisfy the need for cooking energy and for use in Everest Base Camp.

The observations in this report are related to the potential use of biomass charcoal briquettes and improved briquette stoves at high altitudes in Nepal. With proper application of the available technology, biomass briquettes can be a means of providing a convenient source of energy for cooking and space heating, substituting the need for kerosene which is a non-renewable energy source subsidised by the Nepalese government.

The need to improve the locally manufactured biomass charcoal briquettes has been also identified by WWF Nepal Programme. The same problems in the supply of energy exist in similar high mountain regions, such as the conservation areas managed by the WWF-Nepal Programme and the King Mahendra Trust for Nature Conservation. The charcoal briquettes are manufactured from agricultural residue and forest waste products. High firewood consumption for domestic cooking and heating purposes is depleting forest reserves because at the higher altitudes, where tree growth is considerably slower than at the lower altitudes such as in the Terai, regeneration of firewood cannot meet the demands. The author looked at some of the technical, social and financial implications of the produced briquettes and stove.
