The combination would evaporate more water from the pot (should be available from the test data). That would leave a smaller number of litres of water in the pot. That number is then divided into the fuel mass, or the dry fuel mass equivalent of the energy theoretically released from missing fuel. Whichever the case, the resulting specific fuel consumption number would be larger as the divisor is smaller. The higher temperature might cause the lowest burn rate to be higher. That would amplify every difference.<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'>That could explain in part at least why he got variation in the SFC value at different ambient temperatures. <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'>Another contributor could be that the air being warmer it might have a lower relative humidity and the evaporation rate would be higher in consequence.

So the problem may lie with your definition of the turndown ratio.

Both the Indian and Chinese governments developed tests of their own widening the scope of PHU to include power, rate of evaporation, time. Visser (2003) published a version of a water boiling test based on efficiency and appropriate power for boiling and simmering. What motivated this parallel activity? Why isn’t the VITA test in more general use?”<o:p></o:p></span></i></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>One reason the VITA test was not more popular was it had several conceptual errors and a few really poor metrics that gave mis-directing outputs. One is the efficiency of simmering, another is the concept of specific fuel consumption for simmering. Another was the idea of an ‘average efficiency’ meaning an ‘average thermal efficiency’. I believe from my research that the specific fuel consumption for simmering and the average efficiency were both introduced by Baldwin in 1986 or so, before his book came out. Neither are acceptable metrics.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>The document refers to the VITA test the ‘international standard’ which is not supported by the evidence. Three or four minor parties agreed to it and it was never used by the major markets in India and China. Even Eindhoven University didn’t use it and they were a party to drafting it. India pretty much adopted the minority position taken by KK Prasad from Eindhoven and built that into their 1991 test. The Chinese test from that era was very similar. India, interestingly, produced a list of 28 standard sizes of cooking pot which is a record, I believe!<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>The long-forgotten organisation Bois de Feu had a clear understanding of these issues and had a test method in 1982 that didn’t have these problems. They treated the simmering phase very carefully (and differently). Prasad (and Visser who was his student) developed multiple test methods over the years. Piet Visser and I created one in Malawi in about 2007 which later evolved into the ProBEC Test for heat transfer efficiency which is now a SeTAR SOP, currently v1.05 (SeTAR is an independently managed continuation of the 13 year long GIZ/ProBEC project). It doesn’t really predict performance, it gives a real-time heat transfer efficiency report under varying conditions. It is very easy to perform and it supports pot-swapping, similar to the Indian protocol.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>So, ladies and gentlemen, there are no Tier 4 stoves.
