Micro-gasification: Cooking with gas from biomass - Amper

Micro-gasification: Cooking with gas from dry biomass
Two pilot projects based on the Champion model have just started in December 2010 in
Mulanje (Malawi) and Pemba (Mozambique). A 2-year project under BEIA-ESMAP funding
by Worldbank is going to start in 2011 in Uganda with the Centre for Research in Energy
and Energy Conservation (CREEC). This project is expected to create more good examples
of Championand other TLUD applications based on further participatory technology development.
Factory-finished stainless steel version is produced by Servals in Chennai, India (see Section
1 of this Module). Other artesian versions in use in Cambodia, and the Marshall Islands.
An edited excerpt of Anderson’s document on options applying the Champion concepts to
many contexts and requirements:
1. ―Hobbyist‖: produced at a residential garage workbench in the USA with materials from
common hardware stores. It is most appropriate for tinkerers, Scouts, and serious stove
developers/experimenters.
2. ―Refugee‖: produced using a minimum of tools and recycled materials found in refugee
camps. It is most appropriate for humanitarian relief efforts.
3. ―Artisan – factory finished‖: produced as a commercial product in a modest metalwork
shop e.g. in Chennai, India. It is most appropriate for primarily manual production as a
commercial product by small factories.
4. ―Industrial‖: Full-fledged mechanized production. Much of the production could be accomplished
in factories that already make metal containers.
The designs can be scaled to larger units for cottage industry, restaurant and institutional
use.

The test results on http://www.bioenergylists.org/content/testing-andersons-tl from April 2010 in
Cambodia are not representative for a proper operation of the stove. The photos show excessive
flames, which is probably due to too much air while in use and excessive gaps between the 10 cm
length stick-wood fuel.
Examples for adaptation and „hybrid‟ models
Michael N Trevor‘s TLUD version from 2010 shows the flexibility of combining elements
from Anderson‘s Champion, Wendelbo‘s PekoPe and Reddy‘s ‗smokeburner MAGH‘ built in
the Marshall Islands: http://www.bioenergylists.org/node/2427

More details on the Stove Workshop organized by the Seattle Biochar working group
(http://www.seachar.org) on http://seachar.org/wordpress/?p=176.
As a result of the workshop, Art Donnelly, the co-founder of SeaChar, started the transfer of
the concept to Costa Rica and started the promotion of a biochar-making stove, which is
presented next.
