Smoke rings?

topic posted Sat, April 26, 2008 - 11:22 AM by  Jason
The large, roiling, black smoke rings that rose from the playa were awesome. I did not get to talk to th guy doing it, but it looks like he might be driving a volume of diesel fuel w/ an accumulated gas or nitrogen charge. Really like the effect and would like to understand it. Does anyone out there know?

    Yup, about right. It was a gallon of diesel in a modified propane poofer. The guy who started those (others have copied) is Dave King from Reno Controlled Burn.

      We found we can make nice smoke rings with our unmodified fire cannon with about 1/4 gallon gasoline down the barrel. The trick with ours seems to be to open the valve a little more slowly than you would for a normal poof. So open it a bit, hear the hiss, then poof! It's a 10' long 2' pipe coming from a 30 gallon tank at about 45psi and a ball valve.

    Sure would like to see the replies to my post but can't. I haven't paid tribe, so they downgrade my service. Thank Godess I have a life off-line.

        So how about that Raining fuel effect? Anyway to increase the atomization level? Higher pressure and a Smaller Nozzle would blow apart the mushroom right? I've noticed the rings are easyer to form with a lower pressure and Larger Nozzle.

        I started makin smoke rings with only vapor last year, just need to finesse the valve and have a very low psi with no winds. The flame needs to stand nearly veritcal.

          Yeah I have to agree with Knagi on that one, just about every smoke ring (with the exception of only a few) I've seen created resulted in gas raining down.

          Drew and I have gotten a few small ones using about 8 oz of gas at 120psi (quick release) and had no rain, but the weather had to be perfect and the shot dead vertical.

      Yeah, jason, the reason there are premium memberships is to help keep tribe running. The advertisments aren't enough to fix all the problems that pop up with notable increases in traffic. Missing icons, failure-to-load, garbled text and all issues right now, and may be so until new servers are affordable to Tribe.

        Yeah, we get the raining gas effect too. With less fuel that mostly goes away, but I can't recall if we ever got a good ring without the gas rain.
