That's because the comment is classic Riley Clueless, Vaughn. Modern 100#
propane tanks are rated for _at least_ 250# _working_ pressure. Each tank must be tested two twice that working pressure and one out of every 500 is tested to four times working pressure. Pressure relief valves for cooking gas tanks are usually set for 375 psi. The compressed air that goes into the tank doesn't get nearly as hot as his overactive imagination says it does. In fact, the outside of the tank is quite cool to the touch at 280 psi. "Vaughn" wrote in message ... "Richard Riley" wrote in message news Propane tanks are normally rated for 250 LBS. That rating is normally at 120 degrees. 280 PSI air is probably a lot hotter than that. It's been too long since I've done ideal gas law equations, but I seem to remember 250 psi air getting to 300 or 350 F. At a temperature higher than it's rating, a tank is weaker than it's rating. You lost me here. In my experience, 250# air can be any temperature you want it to be. Vaughn |

Dont know about your engine specifically but most everything else runs right around 14 to 1 on the ratio wise. Actually, jets are a different beast from piston engines. Between about 25:1 and 50:1 is normal, even for lightoff fuel flow. Stoichiometrically correct combustion is too hot. |

"Richard Riley" wrote in message ... All he has to do is google "propane air pressure rating fatigue" and he'll get most of what I gave him in my post. As obnoxious as he is, his kids should grow up with a father. All the results of that search that are relevant to using them as air tanks talk about 20# thin metal LP tanks, you dunce, not about 100# steel tanks. Do us all a favor and go play with your legos or something. Look, there's Chuck in the sandbox! Go play! Shoo! |
