Quad 2 Stove

Paul Anderson, Centre for Research in Energy and Energy Conservation (CREEC)

The Centre for Research in Energy and Energy Conservation (CREEC) is a not-for-profit organization which works “to enhance access to modern types of energy through research, training and consultancy”.

The CREEC offers independent stove testing services, and has recently tested the Quad 2 Stove.

For the full test report and method see the pdf:

The center tested the Quad 2 Stove and found that:
The Quad stove boils 5L of water in 27 minutes. To boil and simmer 5L of water, it uses 636g of dry wood and has an energy use of 11713kJ. It has a thermal efficiency of 42% during the high power phase and 41% during simmering. It has a turndown ratio of 1.4, an indication that the stove’s firepower can be controlled for different cooking regimes. Its fuel use is considered to achieve significant, measurabe health and environmental goals according to the Lima Consensus Tiers of stove ranking.

With regards to safety, the stove scored 77.5% and is rated GOOD and is considered a Substantial Improvement according to the Lima Consensus Tiers of stove ranking.

Una reciente evaluación realizada por los refugiados de la Mujer de la Comisión en Haití constató que el precio del carbón ha aumentado en un 40% (CMR y el PMA 2010). Cómo ayudar a las poblaciones sujetas a desarrollar la capacidad de producción de biocombustibles líquidos puede ofrecer una importante solución a la pobreza energética en las comunidades desplazadas de Haití y contribuir a su desarrollo a largo plazo de la autosuficiencia energética.

Proyecto Gaia ha estado trabajando en Haití para promover el etanol y la Estufa CleanCook - una estufa a base de alcohol - como alternativa a las estufas que queman biomasa sólida (es decir, madera, carbón vegetal y briquetas.) El etanol es tan limpia como gas licuado de petróleo, más barata que el carbón, más seguro que el queroseno y tiene más potencial que las briquetas de basura. En África, el Proyecto Gaia ha acumulado más de 2 millones de días de cocinar con la estufa CleanCook sin un solo accidente de cierta importancia.

La pregunta más común que aparezcan durante nuestras conversaciones con los responsables políticos y los empresarios sociales es: ** "¿El suministro de etanol, sea sostenible? Y ¿dónde estaría la oferta provienen de donaciones después tocaban a su fin? "**

Esta es la pregunta clave de la sostenibilidad y la razón de por qué estamos tan interesados en Haití. No sólo fue Haití una vez al líder productor de azúcar y una destilería de etanol de bebidas para la exportación, así como el mercado local, pero también Haití existe en las rutas comerciales durante el cual miles de millones de litros de etanol cada año el flujo de camino a un mercado de combustibles en el los Estados Unidos. Este etanol, sobre todo de Brasil, generalmente el precio más competitivo en el mercado de materias primas, proporcionará una fuente de combustible para Haití-más barato que el petróleo-como Haití acumula su propia producción local (Etiopía Petróleo de datos empresariales). De hecho, el Gobierno brasileño se ha comprometido a donar más de 100.000 litros y un litros otros 400.000 en los próximos dos años.

Chinese Draft Enhancer

Dear Friends

Working on advice brought by Cecil Cook from Lusaka, Peter Coughlin in
Maputo has tried using a short vertical tube (about 400mm) held over the
lighting charcoal to accelerate ignition. This tool is widely used in
Lusaka. It is typically 50mm in diameter and can be made from an piece of
scrap pipe or rolled metal sheet.

Peter reports that people using it have reported faster lighting and a
reduction in emissions during ignition (which is the smoky part of a
charcoal fire).

I tried a similar though larger tube over coal in a bucket and achieved a
dramatic reduction in particulate emissions - certainly more than 90%.


This principle is not only limited to Zambia, it is pretty widely applied by other charcoal users in the region.
Though the most perfect 'chimney' I have got is from China: It came as a standard accessory packed in the carton of the Chinese coal-briquette stove marketed in South Africa under the name of 'Lotti stove'. I think the stove is manfuactured by Shengzhou. So it could be standard chinese practice. The conical shape with the two little air-holes on both sides shortly below the top works much better than a straight tube. We used one at stove camp this year on a two-can TLUD instead of the upper straight can and draft increased considerably. Foto attached, but not sure if it makes it on the list. regards, christa

As the United States biomass thermal and power industry continues to expand, new reliable technologies offering higher efficiency solutions must be introduced. The newly introduced EOS series biomass gasification boiler is among the most energy efficient of AESI’s high-performance, low-maintenance biomass energy plants. The EOS series provides thermal outputs ranging from 600,000 BTU/hr to 20 million BTU/hr, and can be staged to provide increased capacity.

Designed and built by the leaders in the biomass waste to energy market in Europe, Uniconfort, the EOS series builds upon over 50 years of experience and over 4000 successful installations throughout the world. When asked about the highly efficient EOS series, CEO of Uniconfort Davis Zinetti notes, “we must not forget that greater efficiency is associated with less CO2 production. Choosing EOS, therefore, means making a choice in favor of the environment.”

It is explored how programmes for introducing (improved) woodstoves can bejustified in terms of greenhouse gas reduction at competitive cost. The discussion is put in the context of real life observations in Asia and alternative justifications for stove programmes. A few options for putting stoves on the international 'carbon market' are briefly analysed. Tentative results show that a stove project could well result in reduction of CO2 emission at a cost of less than 2 US$/ton.
