Julien and list 1. Thanks very much for providing this cite. I have read most and find it to be a well done thesis. I wish we had more like it.
2. The concepts of char and TLUDs are in here thoroughly. But nothing on the idea of a stove designed to make char. All char is presumed and desired to be consumed. 3. My conclusion (would like to hear more) is that a good case is made (not intentionally) for NOT consuming the produced char in a TLUD (this one fan-powered and widely sold in India as the "Oorja" (started by BP)). Very little gain in overall efficiency as the char is consumed. 4. A major advance was his study of the importance of ash in this "char" period as a poor radiator - thereby responsible for (undesired) high char temperatures. 5. Most everything shown as a function of superficial velocity (Vs) - with 16-17 cm/sec shown as key dividing point in stove behavior.. Above which velocity one swtches from char production to char consumption. I have not seen this before. For his highly automated fan system, measuring Vs was apparently not so difficult. Anyone able to give a way to get an easy estimate of Vs, when there is only natural draft? 6. Quite a bit on the importance of low emissions of CO. 7. Good information on both the experimental and computational side of top-lit (packed bed) stoves. Not much here for rocket stoves. Have I got #3 right? Ron
