Stoves Camp ParticipantsStoves Camp Participants

Fifty two high energy participants attended Stove Camp this year at Colgan’s Island, camping near the river, making and testing stoves, and listening to Fred’s Big Band harmonize so beautifully. Fred and his volunteers cooked breakfast every morning and dinners at nighttime parties on Rocket and TLUD institutional stoves.

Nick Salmons from International Lifeline Fund made a very successful Haitian charcoal stove that was voted “Best in Class” by his peers!

Stove Camp provides a venue for a gathered scientific community to advance knowledge of biomass cook stoves. Participants made new stoves and tested them daily for fuel use and emissions. Every morning the test data was shared and new stoves were constructed.

This year, a great deal of progress was made on charcoal stoves for Haiti. Camp participants, some of whom have worked in Haiti,designed a two-hour Water Boiling Test for Haiti, which uses a Haiti pot
and mimics a typical cooking task, cooking rice and beans. Charcoal stoves were constructed that used less fuel and produced less carbon monoxide compared to traditional Haitian stoves.

See the attached Stoves Camp Report for details of the tests, the interesting findings about the optimum charcoal to use for each stove, and pictures of the stoves tested.

Three friends and I spent last semester at Georgia Tech working on the thermodynamic modeling (and optimization) of cook stoves... I attached a summary of our project and the meat of the analysis section and the Full Report (see the attachments)

While it is possible to build and test the performance of prototype Improved Cook
Stoves without significant capital investment, if the amount of time that it takes to
optimize candidate stove designs could be drastically reduced, then cook stove
technology could reach the hands of many more in developing nations. It was identified
that an end-to-end modeling and optimization effort for Improved Cook Stove (ICS)
design could aid in the development of more efficient and cleaner-burning stoves. The
thermodynamic and heat transfer processes underlying cook stove performance are
tightly coupled, which makes modeling a challenge. The following analysis is a first
attempt at capturing each of the underlying processes of stove performance. The model is
formulated so as to facilitate the optimization of stove geometry. This effort helps
pinpoint the deficiencies of the current state of stove modeling and attempts to
demonstrate the eventual power of a predictive stove model.

Design and Development of a Natural Draft Biomass Gasifier

Naturl Draft Gasifier - KumarNatural Draft Gasifier - Kumar


  • Operates under the principlle of “ Chimney Effectt ”
  • Natural draft caused by density difference


  • No blower is required for the operation
  • Automatically takes the required quantity of air for Gasification
  • Convey the Producer Gas formed by Gasification - Naturally
  • Reduced fuel consumption compared to traditional chulas

More detail, schematic pictures and testing information are in the attached pdfs and in the 2004 discussion:
