Hi Mark I built a cyclone for my gasifier it is made from a 5" truck exhaust pipe. It's heavy enough to disapate heat and welds very well. I entered with a 2" pipe and axhausted with a 2" pipe. The conventional wisdom is 2:1 ratio inlet pipe to dia.of the cyl.I have tried this unit a couple of times and it works well. I understand the "cone" bottom is not a great advantage. I have a simple drawing of it if you want one. [email protected]
