(RWL): I believe that much of your previous work was with "holey" briquettes - whereas this seems to be lump coal. If true, I owner if you can go back to a "holey" design. Speaking as a total novice with coal (watched Andrew once), I like the responses of Andrew and Dan who mention reflectivity - which is much like having "holiness". I think the trick must be getting the chemical heat release per unit area (largely done with increased air) plus radiative feedback (either reflection [with lumps] or "holey design to exceed the heat loss inward. - Stoves List Archives and Website: http://www.crest.org/discussion/stoves/200202/ http://crest.org/discussiongroups/resources/stoves/ (Under construction) http://www.ikweb.com/enuff/public_html/Stoves.html (Original) Stoves List Moderators: Ron Larson, ronallarson@qwest.net Alex English, english@adan.kingston.net Elsen L.
