When used exactly as designed, one cooks a meal with it, then allows it to sit there until the next meal. During this idle time between meals, some of the charcoal that formed is consumed, making room for more fresh fuel to be added for the next meal.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'> I have never seen above-the-grate temperatures in excess of about 1200 degrees F in this machine. In every case, the reactor eventually fills up with partially terrified material and less and less burnable gas evolves until there is none, if one tries for a run longer than about 5 hours.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Pete Stanaitis<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>----------------- <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> Gasification [mailto:gasification-bounces@lists.bioenergylists.org] <b>On Behalf Of </b>Tom Miles<br><b>Sent:</b> Thursday, September 10, 2015 9:24 AM<br><b>To:</b> 'Discussion of biomass pyrolysis and gasification'<br><b>Subject:</b> [Gasification] Open Core Rice Husk Gasifiers<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Does anyone on the list have experience running open core gasifiers on rice husks?
