I guess there must be a diffrence between propane and natural gas..
Slight at best..seems to be the same thing but diffrent..

I cant say anything about Propylene..
Never heard of it.

But propane and oxygen is what we use and the heat is fast and furious..

...zap!

 

Propylene was used around Houston for cutting as it was available from all the local oil/chemical operations. The only advantage I ever heard mentioned by the people I knew who used it was price.

 

LP and the other fuels (other than acet.) are great for heating....make sure you get the correct rose bud as the acet. ones used with LP will not last very long....

 

ive used propylene to cut before, ive noticed it cuts a little smoother than acetylene, but you have to move slower because the flame produced by the propylene isnt as hot.

 

when you order a gas grill there is a deffrence from propane and natural gas

 

propylene or MAPP is hotter than propane but cooler than acetylene and cheaper than both.

A tank of propylene will run a huge rosebud, just like propane. no issues with drawing it out too fast like acetylene.

you can get tips for any fuel gas, natural gas might be "dirtier" than the others.

 

I tried to edit a post and ended up with two so the contents of this post have been wiped out. Read # 9 below.

Propane provides more units of heat (BTUs) per unit of volume at a given pressure than natural gas by about 2.5 to 1, but propane is more costly in most areas served by natural gas distribution systems. Most gas apliances use a different orifice for propane than for natural gas, check with the appliance manufacturer for more information about suitability of your choice of gas for any particular appliance.

Propane is heavier than air while natural gas is lighter. This can be important to know if you "smell" a leak and you know which gas is in use. Both are colorless, odorless, and tasteless and both have stuff called methyl mercaptan added to make leaks detectable to the human nose, that's why they smell the same.

Propylene burns hotter than propane while providing about the same calorific value (same BTUs) as propane. This is not the same as MAPP gas, which is known chemically as methylacetylene-propadiene - more commonly called MAPP gas. MAPP burns cooler than acetylene, hotter than propane, is can often be purchased for less than either. To the best of my knowledge MAPP is stable and does not require dissolution in acetone as does acetylene.

You can google these terms and get some very detailed information in a hurry if needed.

This is about cutting and not heating but interesting info.
