How about an atomizer -- or a carburetor? An atomized or aerosolized 
liquid (which is often referred to as vaporized) remains a liquid. I 
never said it was another state of matter, dangit! :)

I think maybe we're talking past each other -- I'm referring to 
propane's behavior before it reaches the orifice and you other folks are 
talking about after it's passed through?

  Maybe my word choice or tone was infelicitous, but the the way this 
was explained to me won't be corrected by niggling editorializing or 
flaming: Atomized liquids remain liquids. They may behave in a gas-like 
manner when carried in air.

Propane tends more toward the gas-like in it's fluid dynamics than 
liquid-like, but it may exist in either or both states. It boils in the 
tank, becoming a gas. It may partially or even fully recondense in the 
feedline anywhere along the way to the orifice, where it is atomized 
like any other liquid forced through a small opening into an area of 
lower pressure. Those droplets _may_ gasify again on their way through 
the burner tube or they may begin to burn as droplets before finally 
gasifying, like gasoline in an auto engine. (Gaseous gas?)

That's how it was explained to me by my propane supplier. (not Hank 
Hill, BTW) I'm not sure there's much of a difference except as a mental 
exercise anyway. Anything that burns eventually has all or part of it 
become a gas just before conbustion, yes?

I could be wrong, of course, but no one has so far established that to 
my satisfaction. If so, it's an honest error or improper teaching, not 
stupidity or willfullness. Chill out, please.

Even the so-called Aether is coming under scientific investigation again!
