Multiple uses for fuel briquettes..This is in from Nora Feldmar who, as part of her advanced degree in Holland, is introducing briquettes to an active Gypsy community in Hungary:

PCIA Bulletin Issue 29
http://www.pciaonline.org/bulletin/pcia-bulletin-issue-29

This Bulletin focuses fuels for clean burning stoves. As they note, a lot of effort has been focused on wood burning stoves, but in urban areas, stick wood is hard to come by, and charcoal is a much more popular fuel. There's a good reason for this, studies have shown that charcoal stoves have up to 90% less indoor air pollution than similar wood stoves. In urban areas, there is a noticeable improvement in indoor air quality simply by shifting to charcoal burning. Additionally, biomass fuel briquettes, pellets, and other densified paper burning stoves are showing a lot of promise in urban areas so this bulletin profiles projects that use urban waste to create fuel briquettes that can be sold to stove owners.

Quoting "Prof. S.C. Bhattacharya" :

Dear all,

I would be happy to share some publications arising from the following
activities at the Asian Institute of Technology:
1. Sida funded Regional project: An information package (including
construction details) on biomass briquetting machines developed in a
number of Asian countries and design of natural- cross-draft gasifier stoves that can operate continuously is available. The briquetting machines developed
were improvements on standard screw-press heated die design. Cross-flow
gasifier stoves were designed for different sizes; these do not need any
blower and can operate continuously without any smoke.

The briquetting and gasifier stove work I mentioned was carried out under a
Sida-sponsored project at the Asian Institute of Technology (AIT). The
project involved researchers from 12 national research institutes of six
Asian countries, e.g., Bangladesh, Cambodia, Lao PDR, Nepal, Philippines and
Vietnam. The findings of the project were disseminated through national
dissemination seminars in these countries; published "Technology packages"
were distributed widely in the region and are still available for
downloading from the project website. We organized technology transfer
workshops, in which a number of NGOs form the region were invited, on most
of the technologies developed.

(There is no restriction on distribution of the technology packages.)

Unfortunately, the link of the project is not working due to heavy flood in
Thailand; AIT appears to be still under 2 m of water.

2. GTZ funded project on Biocoal: We used the term "Biocoal" (rather than
"Biochar") for charcoal produced from solid organic residues such as
agricultural residues and waste wood. The findings of the project were
reported in a book titled "Biocoal Technology and Economics" by "Regional
Energy Resources Information Center (RERIC)" (email:enreric@ait.ac.th).

The chapters of the 495-page book were:

  • 1. State of the art of biocoal technology,
  • 2. Biocoal technology: A comparison of options and recommendations,
  • 3. Carbonisation of sawdust briquettes,
  • 4. Laboratory-scale batch carbonisation selected residues,
  • 5. Cost and availability of selected residues in Thailand,
  • 6. Characterisation of selected residues,
  • 7.Biocoal: Market requirements and Opportunities in Thailand, and 8. Economics of biocoal production in Thailand.

A few copies of the book are still available with RERIC. A number of
chapters of the book were summarised as journal articles; I will be happy
to
share some of these with interested persons for their personal use and
research purpose.

Other technology packages and published papers of the Sida project can be downloaded from www.retsasia.ait.ac.th. The biomass/stove group may be interested the package on drying, which includes a hybrid drier using solar energy and bioenergy from a gasifier stove, heat output of which could be automatically controlled by using a thermostat.

I also coordinated another regional project (Asian Regional Research Programme in Energy, Environment and Climate, ARRPEEC) funded by Sida in three phases during 1995-2005. One of the 4 projects of ARRPEEC was on biomass. Dissemination booklets of ARRPEEC and some of the papers published can be downloaded from http://www.arrpeec.ait.ac.th

HOW TO MAKE FUEL BRIQUETTES WITHOUT A PRESS (4MB PDF)

YOU CAN MAKE BRIQUETTES BY HAND or WITH A PLASTIC MOLD!

You can use a plastic bottle or other straight-sided plastic container about 4”-8” in diameter to shape the briquette. You will need a piece of wood or banana plant stem or a tin can that will fit into the container as a piston to press water out of the briquette mix, a knife, a plastic bag and some wire.

Please see the attached Presentation for pictures and full details:

MAGH 3G GOOD STOVE

Most adopted stove by poor, tribals and farmers in parts of Andhra Pradesh, India, Already facilitated 1500 stoves and the demand is growing every day.

Measured Drawings are on his site: http://home.fuse.net/engineering/ewb_project.htm

As an alternative to the large compound lever briquette press, here is a small version (Micro Compound Lever Press) that will generate the same or more pressure to make a high quality briquette, is made from wood with hand tools and can produce briquettes at a rate of about 12 in 10 minutes. This would work well in a single family setting, as a classroom demonstration tool, or for any application requiring simplicity and a small footprint.

[MAGH OPEN STOVE](http://e-maghopenstove.blogspot.com/) is an institutional fixed woodgas stove. This stove is useful for cooking needs of up to 100. With primary and secondary air controls it is easy to operate and highly efficient. For making this stove, "Magh CM" stoves are used inside. This stove is installed at "Open House", Hyderabad, a place for destitute youth for cooking their own food, shelter, studies, etc. Implemented under the "Good Stoves and Biochar Communities" Project, Implemented by GEO with support of GoodPlanet.org France. Stove design by Dr. N. Sai Bhaskar Reddy. For more details visit http://e-maghopenstove.blogspot.com/

[MAGH 3G]( http://e-magh3g.blogspot.com/ ) is an adaptation stove. All types of biomass, briquettes and charcoal can be used for cooking. This is an all in one stove.

It was found that many families have at least two or three types of stoves in rural areas for using types of biomass as fuel. Now with just one stove they have the freedom to use all types of Biomass as fuel.

There is an option to control primary air, to control air from the fuel feed side opening, and secondary air (while using TLUD adopter). Weighs less than 2 kgs, 9 inches in height and 7 inches diameter. Most convenient for regular use, travel, relief, refugees, etc. Reusing metal sheet, these stoves are completely hand made. The cost of each stove piece is $5 (USD).

This stove is being facilitated under the "Good Stoves and Biochar Communities" Project, implemented by GEO with the support of GoodPlanet.org This is one of the 40 stoves designed by Dr. N. Sai Bhaskar Reddy, GEO http://www.e-geo.org http://www.goodstove.com/ . For more details visit http://e-magh3g.blogspot.com/
