GEO FUEL BRIQUETTES

Last updated May 02, 2009

GEO fuel briquettes

is a very low cost technology, and also for making briquettes with very less effort. This is screw based system, requires very less energy and space to operate. Briquettes can be made using human power, convenient for young or old in making briquettes from various types of waste material. Small pieces of waste papers, sawdust, leaves, wood shavings, rice husk, etc. can be used as raw material. Any sticky material available in abundant can also be added if required for producing compact and strong briquettes. The cost of each such device made up of iron is less than $8 (USD) or Rs. 400. Various types of stoves are available for using the briquettes, including some of these AVAN and MAGH series stoves can be used. Magh-1 stove with little adoption can also be used for briquettes as fuel. We can also make and use special stoves for the briquettes as fuel.

Introducing Greenie©
For a Greenie-er Happier, Healthier Gambia

Every cause needs a champion and our environment deserves the best. Especially in a society where over 65 % of the population have to live below the official minimum income subsistence threshold “ Environmental protection “ can be a very complex and abstract issue but as soon as we introduce a personal and human element we create a focal point for all to understand.

“ Greenie© “ is a staunch environmentalist, loves all things natural and especially trees. She lives in The Gambia and likes planting things, nursing them and watching them grow – her biggest horror are litter and waste in the environment and she is always happy and eager to explore new ways of re-using and re-cycling them and share her experience.

Our plan is to join her in her adventures of helping to make The Gambia an even more beautiful place to live in and to visit. Her stories will be told in little 24 page pamphlets, showing her in real-life situation photographs accompanied by fun and educational copy-writing. The booklets will be published by PRSP in collaboration with her Artist creator, Caroczel, produced to a professional standard and will be a fun way to create environmental awareness for all age groups within the community.

Fuel efficient wood-burning domestic stoves & Compressed bio-mass briquettes Fuel efficient wood-burning domestic stoves & Compressed bio-mass briquettes

This type of stove has been developed and refined over the last 30 years. It is designed to use wood and other alternative bio-fuels in briquette format. This particular method of construction allows the harmful gases – which on a normal fire are seen as smoke – to be trapped and heated sufficiently to burn and create a secondary combustion. For the same amount of fuel we generate at least twice as much heat for cooking. Add to that other design features in the stove – better air control, a “ skirt “ around the pot base – and we increase its efficiency by as much as 3 times. In effect we only need one third of the fuel in comparison to an open fire to achieve the same result.

The stove will be custom designed for The Gambia’s conditions taking into account the maximum size of a standard domestic cooking pot and dietary requirements. It only comprises of 4 simple parts, its use is easy to learn and safe and it can be manufactured with tooling available on an industrial and local level from new or used steel and parts.

Fuel Briquette Burning at Stoves Camp 2008

This prototype was to check the hole of the briquette and how gasification can do a nice job. As said, starting the fire with few small sticks and then after preheating the chamber, briquettes ignite by themselves and burn throughly. You can help flames with having a stick in the hole while burning. I really liked how the briquette retained its shape after it burned out, so you could still push the next one it without preventing the draft..

But the briquette burned with the surface lit from the combustion chamber, as Larry predicted. You could literally walk away of the stove with the consistent flame going on all the time (I guess the briquettes were good quality :) The air inflow was only through the hole of the briquette.

Funny was, that even when one briquette burned out, the next one ignited and the airflow continued through the hole of the first briquette.
