Congratulations. Have you seen anything similar as a retrofit?<br><br> Can you explain the functions of the small port below and the larger port "up-wind"?<br> <br> This doesn't produce any char?<br><br> We are looking at about an 8 kW flame? Can you vary that by varying anything? <br><br> What is chimney height?<br><br> Where/how does the ash get handled?<br><br>Ron<br><br><hr id="zwchr"><b>From: </b>"Alex English" <english@kingston.net><br><b>To: </b>"Discussion of biomass cooking stoves" <stoves@lists.bioenergylists.org><br><b>Sent: </b>Saturday, January 14, 2012 12:42:22 PM<br><b>Subject: </b>[Stoves] The upside of Down feed<br><br>Stovers,<br>Its a long winter, and old bones and cord wood and Crispin make me <br>think......<br><br>Attached are two pictures which show my early steps towards <br>understanding the limitations of gravity with stoves.<br>One shows a wedge shaped door spacer "the Artful Dodger' which picks the <br>stove's pocket for draft and connect it to any burner idea I can cobble <br>together.<br>The other shows it operating with a burner that has a small unsealed <br>hopper for pellets. I use a loose lid/follower to ride down on the <br>pellets. So far there has been no fumes coming up and out, and the fire <br>has not chased the air and fuel back into the hopper. The bottom throat <br>on the hopper is about 5 cm diameter. It operates continuously at one <br>speed with an input of 1.6 kg of wood pellet per hour.<br><br>For a video<br>http://www.youtube.com/watch?v=yOlu7DdX1gI&feature=youtu.be <br><http://www.youtube.com/watch?v=yOlu7DdX1gI&feature=youtu.be><br><br>May you find inspiration in the foolishness of others.<br>Alex<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></body></html>
