Gasifier Experimenters Kit - Pole Shift Survival Information

Gasifier Experimenters KitIn addition to preheating the air,the heat exchange tubes also coolthe product gas. I was surprised tosee gas exiting the top of the gascowling at 150-210F. Yes that iscorrect, 100C or less. Comparewith typical no air preheating orgas cooling configurations whichhave gas exit temps in the 200-400C range. Hot gas is muchmore difficult to processdownstream than cool gas.Cyclones, filters, plumbing andpumps are all complicated by hightemp gas.This success of this "gas coolingvia air preheating" suggests thepotential of eliminating the radiatorall together. In the next run I'mgoing to double the length of theair preheating lines, put fins on thecyclone, increase the size of thegranular filter, and see if we cando without the radiator (or in otherwords, incorporate the radiatorinto the gasifier).
