Dear Crispin,<div><br></div><div>Thanks for highlighting me on that issue.</div><div>Is such a stove to complicatied or expencive for the low income households of Africa?</div><div><br></div><div>If you put a natural draft gasifier in an enclosure to get the primary air prehated using dry fuel, I would guess that you could use fuel of higher moisture content, later on. </div><div><br></div><div>I understand that very dry fuel might burn so fast, that PM might enter the indoor air.</div><div>I also think a fan driven gasifier might speed up that process and make it even worse?</div><div><br></div><div>Otto <br><br><div><div id="SkyDrivePlaceholder"></div>> From: crispinpigott@gmail.com<br>> To: stoves@lists.bioenergylists.org<br>> Date: Fri, 10 Feb 2012 09:38:06 -0500<br>> Subject: Re: [Stoves] Fuelwood moisture and wood stove<br>> <br>> Dear Otto<br>> <br>> >I have "never" heard about stoves. which can burn wet wood cleanly, apart<br>> from boilers, may be.<br>> <br>> There are good reasons why boilers can burn wet wood - if they are designed<br>> to do so.<br>> <br>> I demonstrated to Dr AD Karve a stove that was burning very damp wood at<br>> ETHOS, perhaps 2007 - was burning very cleanly. Basically it requires<br>> preheating the primary air. As very few stoves preheat the primary air, they<br>> do not deal with damp fuel well.<br>> <br>> Very dry fuel can also make a lot of condensed particulates, principally by<br>> burning so fast that it runs out of secondary air. That is one way to<br>> manufacture carbon nanotubes.<br>> <br>> Regards<br>> Crispin<br>> <br>> <br>> <br>> _______________________________________________<br>> Stoves mailing list<br>> <br>> to Send a Message to the list, use the email address<br>> stoves@lists.bioenergylists.org<br>> <br>> to UNSUBSCRIBE or Change your List Settings use the web page<br>> http://lists.bioenergylists.org/mailman/listinfo/stoves_lists.bioenergylists.org<br>> <br>> for more Biomass Cooking Stoves, News and Information see our web site:<br>> http://www.bioenergylists.org/<br>> <br></div></div> </div></body>
