But I find the methodology and conclusion wrong.</div><div class=""><br class=""></div><div class="">2. Re methodology for TLUDs, it is generally not possible to do what Dr. Lloyd asserts - testing a stove alternatively back forth with and without char-making. The equations are designed to predict stove efficiency when it can’t be measured. There may be stoves that can do what he asserts, but I don’t know of any. Doing that testing will be a big help in this “equation debate”. The intent of the arithmetic in his second paragraph is to come up with a thermal efficiency number that allows comparison with stoves that only inefficiently make char. One key purpose of that comparison is for using the existing Tier system. This computation however should have nothing to do with the utility of a Tier system; that is a different topic. The issue here is one of accuracy of the computation.</div><div class=""><br class=""></div><div class="">3. Dr. Lloyd’s key assumption in “case 2” (not a measurement) below was for 29% char making. If that number had instead been 27%, he would have achieved the 30% of “case 1” almost exactly. A 2 % difference in one place leads to a 2.1% difference in another. To encourage others to get into this, I intentionally do not show all the intermediate steps, but I am sure Philip will tell us if this is so.</div><div class=""><br class=""></div><div class="">4. In the perfectly valid 2nd case, the calculated final 32.1% stove thermal efficiency would be the logical value to insert in Tier comparisons - not 30%. To repeat - the methodology that Dr. Lloyd correctly employs is directional - it has always been used to predict what you can’t measure. If you can measure the 30% you have no need for this equation.</div><div class=""><br class=""></div><div class="">5. As to Dr. Lloyd’s “no benefit” conclusion, I fail to see how any of the calculations allows that. From the standpoint of the person wanting charcoal, it is certainly preferable to have the world believe 32.1% rather than the arbitrary 30% for stove thermal efficiency.</div><div class=""><br class=""></div><div class="">6. I believe this answers Paul Anderson’s query also below. </div><div class=""><br class=""></div><div class="">7. I am working on a more general approach to this which can remove the objections of a negative sign in the denominator. This to answer Professor Bond’s concerns. It will be based on the observation that the objectionable (1-e2) is the same as (e1+io). And one can alternatively argue all this with inverting the basis equation to read e1/e3 = 1-e2 = e1+io.</div><div class=""><br class=""></div><div class="">8. Re the conversation with Professor Bond, this is to add that the ISO approach also has a document on Tiers - my main concern in this discussion. My promised material in #7 will cover that.</div><div class=""><br class=""></div><div class="">9.

More wood would be needed, because not all the wood would be combusted – some would be left as char. If you fed 0.395kg wood to be turned into char at 29% efficiency, and the char had an LHV of 28MJ/kg, then the char would have an energy of 0.395*28000*0.29=3163kJ. The wood from which it was prepared had an energy content of 5930kJ, which was what was needed to boil the water in the absence of char production. So 5930-3163 = 2768kJ of additional energy* would be needed to boil the water if there was char production. At 15MJ/kg, this is 2768/15000 = 0.185kg extra wood, or an increase of 47% in the wood supply. The total energy supplied would then be 5930+2768 = 8698kJ. The energy efficiency of cooking would therefore fall to 1779/8698*100 = 20.5%, while the efficiency of char production would have been 3163/8698*100 = 36.4%.

Actually wood takes up (has) too much WEIGHT. Wood has 3 times (or more, if the char is poorly made) the ENERGY value of charcoal that could come from that char. But it has about 5 times the DRY weight of the char, plus there can be 20 to 50% moisture content to make the wood even heavier. <span class="Apple-converted-space"> </span><br class=""><br class="">And the charcoal has almost double (30 vs. 16) the energy content by weight, but char is so much lighter per unit of volume. So the trucks are buldging upward and sideways with the sacks of charcoal strapped to them. Weight of charcoal is not a problem for most transport.<br class=""><br class="">Apart from the transportation issue, I believe that the appeal of charcoal is that it does not smoke (not much). CO is invisible and deadly, but the people learn to cook on the balcony or keep some air flowing. And it does not turn the bottom of the pots black.<br class=""><br class="">Charcoal is an attractive fuel. Too bad it is made by processes that throw away 2/3rds of the energy.
