Micro-gasification: Cooking with gas from dry biomass There is a type of natural draft stove with a conical fuel hopper. It is not a batch-loaded fanassisted TLUD, but a continuous feed also referred to as a ‗quasi‘ or ‗semi‘-gasifier. It is therefore much shorter than the rather tall and top-heavy TLUD rice husk gasifiers. REAP (Resource Efficient Agricultural Production) has also introduced the model in West Africa. It is a promising option for areas, where stove-height might be an obstacle for cultural acceptance, electricity access is challenging and purchasing power rather demands low-cost options. Mayon Turbo Stove (Philippines / Gambia / Senegal) Target area: Currently promoted by REAP in Philippines, Fuel type: Rice husk, also peanut shell and other shells and husks Designed by: Developed by REAP Canada, based on LoTrau from Vietnam Retail price: 15-20 USD Numbers sold: Over 5,000 in Philippines, 500 in Gambia and Senegal Start of production: In 2003 Made by: Local artisans Source: Contact: Roger Samson http://www.hedon.info/View+Stove? info@reap-canada.com itemId=8957 Production promo- In order to encourage more stove production around the world, tion: REAP Canada has prepared an International Marketing and Manufacturing Package which includes information on what is needed to manufacture and disseminate the stove at the local level. It includes general information on the stove, design drawings for manufacture, an instruction manual, brochures, and former case studies and can be obtained for 200 Canadian Dollars from REAP. Short Description: Bottom-lit continuous feed natural draft gasifier, dimensions depending on model 165 or 178 mm diameter, Weight 4-5 kg Made from sheet metal and steel by local artisans. Features: conical fuel hopper open on top, combustion chamber in the centre of hopper, secondary air holes enhance the complete combustion. Handling: Can be fed continuously from the open top of the conical hopper. Tapping to introduce new fuel to the combustion chamber in the centre of the hopper is required every 7-10 minutes. Char-making ability: No, burns to ash, which can be used as a fertilizer. User feedback: Fast, convenient, smokeless, economical to operate, enables considerable savings, good pot stability, uses a wide range of cheap fuels Accidents: None known. Performance data: 1 liter of water can boil in 6-7 minutes.

It was introduced in the Gambia in 2003. HERA – GIZ Manual Micro-gasification Version 1.01 January 2011 47
Micro-gasification: Cooking with gas from dry biomass Outlook rice husk burning gas stoves For institutions and restaurants, a 2-3 pot remote-burner stove can be found at http://www.minangjordanindo.com/multipleburneerricehuskstove.htm More rice husk-burning stove designs once prototyped and presented at a wood gasifier workshop organized by ARECOP in 2003 can be found in the handbook compiled by Alexis Belonio http://www.bioenergylists.org/stovesdoc/Belonio/Belonio_gasifier.pdf. A very comprehensive training manual on Rice husk gas stoves updated by Alexis Belonio and others in April 2010 can be obtained upon request by email from crhet_cpu@yahoo.com. Further information is available on www.crhet.org. It includes learning modules about the underlying principles and the development of the technology. It features construction and marketing options, testing reports and detailed plans of the rice husk gas stove. HERA – GIZ Manual Micro-gasification Version 1.01 January 2011 48
