But Alex' suggestion earlier today has much more merit - I wish I had thought of it. I've never liked that "retort" approach for cookstoves, since there is close to zero capability to control power levels. But that is not important for your type of space heating. Could lower costs and produce considerable char relatively easily. I also like Alex mentioning the availability of H2 - what you want for cleaner heating we don't want in char.</div><div class=""><br class=""></div><div class="">Ron</div><div class=""><br class=""></div><br class=""><div><blockquote type="cite" class=""><div class="">On Jul 29, 2018, at 5:19 AM, Norbert Senf <<a href="mailto:norbert.senf@gmail.com" class="">norbert.senf@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><div class="gmail_extra"><div class="gmail_quote">On Sat, Jul 28, 2018 at 7:05 PM, Ronal W.

I believe a TLUD design could work with such fuel. To be explored.</div></blockquote><div class=""><br class=""></div><div class="">Interesting question. It would completely change the handling of the fuel. You'd have to store it in bins, rather than stacking. Getting a load from the woodshed and stacking it in the heater would be very different. It would be an interesting experiment to try, maybe we'll try a load like that in our lab this winter, just to see how it burns. I'd guess it would need some kind of basket in the firebox, so that you could get air all around it. There are, for example, pellet baskets that you can use in a regular stove or fireplace:<br class=""><a href="https://www.flickr.com/photos/daphne_blue/2957483166" class="">https://www.flickr.com/photos/daphne_blue/2957483166</a><br class=""></div></div><br class="">-- <br class=""><div class="gmail_signature">Norbert Senf<br class="">Masonry Stove Builders<br class="">25 Brouse Road, RR 5<br class="">Shawville Québec J0X 2Y0<br class="">819.647.5092<br class=""><a href="http://www.heatkit.com/" target="_blank" class="">www.heatkit.com</a></div>
