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.

Thanks! I'd love to see a sketch. 5" seems pretty minimal; the riser inside
the cyclone would probably be limited to 2-or-2-1/2", and the tangential
entry about the same, but lots of light-phase, vacuum conveyance systems are
built with 2-1/2" tubing and spiral PVC hose. Exhaust tube is fun to weld
with either a little MIG or oxy-acetylene system. Good choice.
For some reason or other (it seems intentional) all of the high-efficiency
cyclones I have worked with have been constructed with long, narrow-angled
conical bottoms. The powder must be exposed to increasing centrifugal forces
as it reaches the discharge zone, to keep it out of the exit airstream, I
reason. But I'm certain that there's a point of diminishing return and KISS
always applies!
