Hi Ron, I think that Chinese cooks are used to using coal in the shape of honeycomb briquettes. They are used to top loaded stoves and no tending and maybe little turn down. Even sticks of wood are loaded vertically in a cylinder, maybe 18" deep or so. Adding secondary air seems to be an well known old trick. The Chinese seem to me to have known all the tricks for a couple of generations (or more?).
So a TLUD is similar in operation to Chinese stoves that burn coal. It's not a new interest rather the TLUD type stove seems to be pretty old. Maybe someone from China could share the history? It seems to me that hundreds of Chinese manufacturers have a good understanding of the TLUD technology with and without fans. The stoves made for China can be heavily built and are intended for the richer Chinese consumer, except for the millions and millions of $2-$6 coal burning TLUDs. I think that maybe 20 or more manufacturers are working to improve their stoves using emissions equipment and will be developing tuned TLUD, Fan, and Natural Draft stoves that have very low emissions. The Chinese Alliance for Clean Stoves is helping manufacturers and Dr. Liu and Dr. Dong at the testing centers in Beijing (funded by the Global Alliance) are a big help as well. China is a wonderful and supportive country where innovation can become useful quickly. The Chinese government seems to me to be extremely efficient and supportive of green technology.
