GF, no, I have no info about passing "red hot exhaust" through the reaction zone. But what do you mean by red hot ? 450-500 °C? That's mighty hot enough to burn your fingers, but it would actually cool teh r-zone down ! Also, if i understand you right, it would drag even more inert gas into the reaction , thus leading to a less rich gas. We want the energy, but not the stuff! Another thing would be an indirect heating of the dry biomass and introduce these fumes into the running gasifier. But in the end this would not be more than a enlarged pyrolisis zone. We would still need some high temperature heat to crack the tars and reduce . And yes, very dry biomass might ask for some additional water in form of steam. Don't know if I missed your point, if so, please explain!
