Ok, can you people read, I am going to be using a canister of air, oxygen, or whatever to fill a second chamber. I want this to push out the exaust, i could care less if it makes a better burn rate. Ignore the canister idea for now, i just wanted to do that to make it easyr to use, without having to pump it up or have a compresor with me. The fan will still be there to mix but have nothing to do with venting

The idea is stupid if I say. expensive and takes the portability away from combustions.

ofcourse because you are increasing the o2 levels... atmospheric air is only 18.8 (right?)% o2. by injecting more o2 your replacing alot of the N2 in the air (80ish percent right?) with more o2 this means you can add more propane without increasing pressure like a hybrid... if you add more propane with atmospheric air you will not burn all of it because you need more o2 to burn the rest. by injecting the o2 you are replacing alot of the useless gasses n2 and w.e else if just floating around with pure o2.. because your not vacuming hte chamber and injecting it with o2 its not gunna be like 95% oxygen and 5 propane but you will get more oxygen letting you add more propane


i also thing that this is safe... propane generaly only generate 60psi peak in the best conditions (right? sorry im taking this from memory). that leaves about 90 psi more room to get to the max pressure that use pneumatic guys take our sch40s up to (150). that means you need to get 250% the amount of combustion... correct me if im wrong but if metered propane gives you 100% optimum so you would have to double that to even get close to dangerous

How in any way does it take away from the protability... CANISTER, not compresor, this is the idea

And scope, i know what you mean to displace the exaust with oxygen to make, basicaly "air", im not shure how much i would have to add. does anyone know the oxygen volume of air to inert gases?

It requires you to get oxygen filled and bought.
And its expensive.

It is still going to be uneconomical and extremely inconvenient.
