A few people have been asked for input and then I will circulate it further. It is very much open for discussion. The Stove Testing Toolbox is a set of agreed methods with their attendant definitions and metrics, each of which exists independently and is valid on its own. At the moment there are two ‘tools’ that seem to be well defined enough to work well.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;mso-fareast-language:EN-US'>One is for determining the heat transfer efficiency of a hot stove at high power and the other is for determining the average heat transfer efficiency over a long burn at one or more power levels including ignition. The latter captures the influence of the thermal mass of a heavy stove – something building into the Chinese National Standard at the moment though it does so in a manner that has not been examined in much detail. Emissions are easily added to the TET numbers based on the mass emitted per net MJ in the pot. Determining the MJ in the pot of a wok or for frying has been a problem. This has been addressed.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;mso-fareast-language:EN-US'>The thermal efficiency tests (TET) are similar to the BS, Indian and SeTAR tests meaning they track the heat transferred including the Cp of the pot.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;mso-fareast-language:EN-US'>More details will follow when the documentation is organised.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;mso-fareast-language:EN-US'>Regards<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;mso-fareast-language:EN-US'>Crispin<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;mso-fareast-language:EN-US'>This was not cross-posted to the biochar list<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;mso-fareast-language:EN-US'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0mm 0mm 0mm'><p class=MsoNormal><b><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:windowtext'>+++++++</span></b><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:windowtext'><o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Stovers and biochar folks.<br><br>The message below and attachment were sent but not distributed (because of too many other recipients).<br><br>That explains why there was so little discussion!! <br><br>I consider this document to be highly important.
