Fourth Test
 | | Propane, High Pressure Regulator (60psi), Logan, Dual Control Valve, 6' Pipe |
I soldered together a dual control valve (see second picture). It's just two valves in parallel: a normal shut-off valve and a quarter-turn ball valve. The idea is to put this dual valve in the propane line. With the ball valve closed, open the regular valve a little bit and light the propane - this constitutes the pilot light. Then, when you  | | Dual Control Valve |
open the ball valve, all 60psi of the propane rushes out creating a larger jet of flame. This worked just fine but an interesting thing also happened: There is a ~20' of 3/8" i.d. tubing between the regulator and the dual control valve resulting in a volume of ~80 cubic inches. Since the pilot valve is only allowing a few psi of pressue out the  | | Moderate Fireball |
nozzle the pressure difference is taking up residence in that tubing which, in effects, acts as an accumulator. So as soon as the ball valve is opened we would get a moderately sized fireball that lasted half a second before the regular jet of fire took its place. This inspired me to add an acumulator and move directly to test number five.
