Propane (Oh My!)

[DaShooster]

I have a question:

What is the best way and how do I set up a propane powered cannon? I belive that there are some ratios for charge size and special parts etc. What do I need to know about this. Have any of you had sucess with propane or should I move in a different direction. I have heard some cool stories about these cannon and got interested.

Thanks for your help and advice!

first off how old are u? and do u have a sence of wat to do with propane and how dangerous it is, if u do ok.

But if u dont stay away from Propane it is really dangerous and burns with an intense CLEAR flame so be very careful if u really want to work with propane. Me I like pneumatics I think their the best but hey wat do I know so if u are going to work with it just be careful and dont blow yourself up

propane doesnt burn with a clear flame, it urns with a blue or orange flame.

still, in bright light it may be hard to see. dont smoke while finding leaks

It would only burn with a clear flame at its hottest point...
temp wise red is lowest, blue is hotter, clear is hottest

Propane is not dangerous at all.
I hate noobs that think just be cause they have 50 or so posts they are all of a sudden experts.

The hotter a flame is doesn't determine the color of it.
Fire burns with a color based on what it consists of. For example, Methyl Alcohol, or Methanol, (used in drag racing cars, among other things) burns with an almost clear flame because there are little to no impurities in it.

Pit crews have to be very careful of injury because any fire would be real hard to see. Though someone screaming might be a giveaway there , but still.

Propane can be dangerous, it all depends on what you do with it. It's all based on if you are precautious and if you know what you're doing, then it is relatively safe, though it's never going to be 100% as something out of your control could always go wrong.

Hey Ben, for a noob he hit the nail rite on the head, didn't he?

but also how perfect the fuel to air ratio is depicts flame color... for example propane in a torch if the fuel/air ratio is out of wack will not be jet hot... same goes with a Bunsen burner... the better the ratio, the hotter and cleaner the flame, and the more perfect the color...

does anyone know if temperature in a flame displays color the same way excited electrons do when they fall back to ground state.

Ben, listen to the guy with 400 less posts. He makes a valid point.

Correct, the amount of oxygen in the reaction affects the flame's temperature. Less oxygen means a poor combustion reaction, and a cool flame. Where-as a perfect ratio of oxygen to combustant results in a more perfect, and hotter, flame.

Edit: I forgot to answer you're other question. I'm pretty sure that a flames color appears to be as such just like you said. The electrons get excited and when they fall back down to ground state and they emit a photon.

[WOW!!]

The best way is to take a propane tank and inseret in the back of the cannon, close here up and you are good to go.
