<div>Hi Mark</div>
<div>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.</div>

<br>> I?ll see what I can dig up. I did a project without a final baghouse and was amazed at how much the 1% loss of efficiency really amounted to! (it?s all super-fines). But getting the first 98-or-99% collected takes a huge load off the baghouse. A critical part of the cyclone is a long-ish downcomer that allow the material to accumulate and discharge with out disrupting the vortex dynamics. Learned by experience! Also, stacked Posiflate valves in lieu of a rotary airlock.<br>

><br>><br>> Hi mark<br>><br>> I was wondering if you or some one on the list has the math for the efficiency ratios for cyclones ie. Tall skinny vrs short fat cfm, volume? Particulates?<br>><br>> Thanks<br>
