As the air is heated going down, it counteracts the vertical draft in the central chamber where the fire is. This limits the excess air without using a choke-type controller. The vertical position of the air entrance holes on the side of the body sets the EA level that is achieved. </span></div><div style="width: 100%; font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);"><span style="font-size: initial; text-align: initial; line-height: initial;"><br></span></div><div style="width: 100%; font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);"><span style="font-size: initial; text-align: initial; line-height: initial;">Regards </span></div><div style="width: 100%; font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);"><span style="font-size: initial; text-align: initial; line-height: initial;">Crispin </span></div> <div style="width: 100%; font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);"><br style="display:initial"></div> <div style="font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);"></div> <table width="100%" style="background-color:white;border-spacing:0px;"> <tbody><tr><td colspan="2" style="font-size: initial; text-align: initial; background-color: rgb(255, 255, 255);"> <div id="_persistentHeader" style="border-style: solid none none; border-top-color: rgb(181, 196, 223); border-top-width: 1pt; padding: 3pt 0in 0in; font-family: Tahoma, 'BB Alpha Sans', 'Slate Pro'; font-size: 10pt;"> <div><b>From: </b>mnurhuda@ub.ac.id</div><div><b>Sent: </b>Monday, December 16, 2013 20:01</div><div><b>To: </b>Discussion of biomass cooking stoves</div><div><b>Reply To: </b>Discussion of biomass cooking stoves</div><div><b>Subject: </b>Re: [Stoves] Help needed to deal with excess rain</div></div></td></tr></tbody></table><div style="border-style: solid none none; border-top-color: rgb(186, 188, 209); border-top-width: 1pt; font-size: initial; text-align: initial; background-color: rgb(255, 255, 255);"></div><br><div id="_originalContent" style="">It seems that the stove is Vesto stove or its variant, is that right?<br><br><br>On Mon, 16 Dec 2013 16:37:27 -0000, "George Riegg Gambia"<br><icecool@qanet.gm> wrote:<br>> Fellow stovers - and briquetteers,<br>> <br>> Compared to some disasters happening around the globe our own<br>predicament<br>> here is almost insignificant.<br>> <br>> However, after many years of struggling, researching (with a lot of<br>> practical help and encouragement from some people here - THANK YOU) we<br>are<br>> finally moving on in this small and almost forgotten little corner of<br>the<br>> world - The Gambia.<br>> <br>> In 2011/12 we carried out an 18 months pilot under the WB BEIA<br>initiative<br>> researching and finally adapting what in my mind is a GREAT stove to<br>make<br>> it - almost - "our own" - the Furno EES - based on Chispin's Vesto and<br>> adapted to local needs and manufacturing capabilities.<br>> <br>> Now we are waiting until the "big boys" can agree to pre-finance the<br>first<br>> test batch of 500 to be locally made.The 24 households who have been<br>doing<br>> our long-term (almost by default) on-the-ground research could not<br>imagine<br>> how to do without it anymore!<br>> <br>> At the same time we researched, tested and started making briquettes<br>with<br>> Richard's help and encouragement.
