IFB stainless liner school rocket stove skirt detail

On a recent trip to Haiti, I completed the first prototype of a new school rocket stove. This one has a 26 ga 330 stainless steel firebox liner, 2½" insulating firebrick walls, and galvanized steel outer shell. The skirt is 304 stainless inside, 1" ceramic fiber in the skirt floor and walls, and galvanized steel outer. The mouth and firebox are 6½" x 6½". The pot is 40 qts with the top diameter about 1/4" larger than the diameter near the bottom, and is imported. The locally available spherical bottom pots made skirt construction extremely difficult. We hope to someday produce this stove in quantity at a combined vocational school/stove factory.M2k Tekno

ETHOS Cooking Stoves Conference in Kirkland, Washington January, 2015.
for more about the next ETHOS Conference see http://www.ethoscon.com/

The ETHOS conference brings together people involved in stove design, dissemination, and testing from Universities, Government, and Non Government organizations, and has themes around the topics of improving cook stove design and performance, reducing emissions, and improving stove adoption, but listening to the needs of the people using the stoves. It ends with the 'lighting of the stoves' which is a demonstration of some of the cooking stoves that people have talked about in the conference.

In addition to capturing photos of the stoves, this year I captured a few pictures of the crowd of attendees comparing stove designs, toasting marshmallows, etc.

The big green stove is the InStove institutional rocket stove http://instove.org/

The lovely people taking pictures were from CREEC ( Energy and Energy Conservation ) which presented a great analysis of current cooking stove tests and some insights to improve them. They also noted that fans typically fail in Uganda, and there are no fans available to replace them.
For more about CREEC see http://creec.or.ug

StoveTec and Aprovecho presented some interesting innovations in stove design that they hope to field test in the coming year. The light green stove has an insulated top door for adding fuel to their TLUD style stove. The purple stove is their rocket stove that has been optimized for improved particulate emissions, with an improved set of colors.

2 - for - 1 ECO-KALAN BINGKA OVEN

2 FUELS FOR I STOVE: COCONUT SHELL CHARCOAL OR WOOD (IPIL-IPIL) (Leucaena leuco

In operation with Wood Fuel and Charcoal

Eco-Kalan has adapted their Binkga Oven (named ofter the rice cakes that the ovens make) to use both locally available coconut charcoal and stick wood fuel.

The system uses the same oven bottom, and two different covers, one for wood and one for charcoal. Both ovens can bake high quality Bingka rice cakes, but with two different levels of particulate emissions. (Notice the soot on the wood fired oven). However, both ovens are cleaner than the hornohan stove that Eco-Kalan would like to replace.

The Bingka Oven works over a range of cooking temperatures (325 deg. F - 500 deg F) and has can cook both bingka and torta breads (with or without filling). Rebecca is anticipating that it will also work for a wide variety of other baked goods.

They have demonstrated the oven for local parents, teachers, government officials, and others. They have also reached out to people who work with remote communities that in the mountains. The first commercial production will target bakers who are preparing the bingka and torta on the more common and smokey hornohan stoves and anticipate the newer stove will give these bakers the ability to make high quality goods with lower costs and improved health.

Tom varios amigos me han escrito que no reciben el documento aqui te lo mando, si lo van a poner en la web por favor agregar los siguientes comentarios

Està fabricada con làmina de 3 milìmetros en la parte exterior y la càmara interna es de tubo acero al carbòn de 5 milìmetros
tengo varios modelos en pruebas con gente que la usa todos los dias y los resultados hasta el momento son los siguientes
A- en nuetro medio un negocio comun es la venta de tortillas, una de las usuarias ha logrado producir 800 tortillas con 10 libras de leña.
B- la primera estufa con 2 quemadores tiene ya 8 meses de prueba y las condiciones de la càmara son exelentes no se ve deterioro alguno, esto nos da un parametro de vida de mas o menos 4 años de uso diario.
C-los usuarios que estan haciendo las pruebas estan muy contentos por el desempeño y el ahorro, pues antes gastaban $7.50 usd en gas licuado (LPG) y con este modelo ahorran $5.00 por dia con un ahorro total de $1,800.00 usd por año
D- los resultados finales con relacion al peso de la leña en comparacion de estufa tradicional estaran listos en 2 semanas.
