Fire Pong
For EMF 2016, a small group of us are working on a series of fire effects to be incorporated into an interactive game of some sort (provisionally "pong").
Puffers (a.k.a. "Poofers")
Puffers consist of an "accumulator" tank (usually an empty gas bottle), which is filled from a "feed" tank (a full propane bottle). The supply is regulated to somewhere up to 60 PSI. The accumulator tank is connected to a long "barrel" through a large-bore value which can open and close quickly. This may be a manual ball value or an electronic solenoid value. The accumulator tank is also connected to a pilot flame at the end of the barrel, through a low-pressure regulator.
When the ball/solenoid value is opened, the medium pressure propane in the accumulator tank shoots up the barrel, and is ignited at the end by the pilot flame. This creates a brief "puff" of fire.
Puffers come in many sizes from hand-held to truck-mounted, and can create a puff from a few tens of centimeters tall to anything up to and exceeding 10 meters!
