BioEnergy Lists: Biomass Cooking Stoves

With the purpose of developing a stove that uses a different fuel to petroleum and other conventional, 4 years ago was initiated the development of an alcohol stove, which presented several problems

Coming of the Corporate Biomass Stove - Mass Manufacturing to Save the Day?
Charlie Sellers, November 23, 2008

For the last several years there has been a huge amount of activity in what we might call "corporate stoving" - it is not as if corporations of one kind or another have not always had cooking wares for sale (certainly in the developed world!), but they have not always been this active in developing countries - the market certainly is huge, but the margins are uncertain and the customers non-traditional. These welcome players include British Petroleum, Bosch Siemens, Philips Electronics, and the Shell Foundation and their more technology rich mass manufacturable stoves have the potential to reduce fuel consumption by 50% and drop emissions significantly, and result in deployments of tens of millions of units each. This short article is a collection of photos and links about some of the most recent stoves which might be deployed in larger numbers.

INVERTED-DOWNDRAFT COAL GASIFIER FOR SMALL SCALE INDUSTRY THERMAL APPLICATION

Gasifier With Jet Burner

Fuel source for small-scale industry heating application is becoming expensive. This is more so for food, grain, and other processing industries in Indonesia where the energy sources for various processes are highly dependent on conventional fuel. At present, the cost of LPG went up to IDR 7,000 per kg while kerosene and diesel to as high as IDR 12,000 and IDR 5,500 per liter, respectively.

SMALL-SCALE INDUSTRY COAL GASIFIER STOVE FOR FRYING FOOD PRODUCTS

Coal Stove

The cost of frying food products for small-scale industry bake shop is now becoming expensive brought about by the ever-increasing cost of LPG fuel. Based on the experience of Sakura Ampan Bakeshop in Jakarta Pusat, Indonesia, a single-burner gas stove consumes about 2.2 kilogram of LPG per hour. With the present cost of LPG of IDR 350,000.00 per 50-kg tank, the bakeshop is spending around IDR 15,400.00 per hour for cooking and/or frying food products. For 8 hours operation per day, around IDR 123,200.00 is spent for its cooking/frying activities using LPG.

Coal, which is abundant in supply and so far the cheapest of the fuels available in Indonesia, is the only alternative fuel to LPG that is considered economical and feasible for small-scale industry use. However, the emission of sulfur dioxide (SO2), which is the predominant reason for the unacceptability of this fuel among households, makes the use of coal unpopular for industry application. Nevertheless, this problem is now resolved by gasification. Injecting lesser amount of air to the coal bed during gasification in the stove greatly reduced the amount of SO2 emission as compared with the conventional direct combustion burning of fuel. By gasification, coal can be conveniently used with almost no SO2 emission during cooking.

PCIA Bulletin Issue #17
Partners in Clean Indoor Air, November 6, 2008

Dear PCIA Partners,

We have published the 17th issue of the PCIA Bulletin!

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.

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

Greenie

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

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.
Briquette

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.
