Boiling point of oils (vegetable & motor mostly)
I haven't found any listings for boiling points of oils but have found smoke point, flash point and auto-ignition point.
The reason I'm asking is looking at heating oil in a copper or steel tube as it feeds an oil burner. I'm concerned that the tube will be heated too
much (say 600-1,000F maybe more in extreme points) and something catastrophic would happen in the tubing or feed resevoir.
Ideally the oil would be as hot as possible when it reaches the air stream to achieve auto-ignition when contacting the air stream.
I'm also concerned about other reactions with the oil at high temps like some kind of polymerization (or something that may gum up the flow). IDK if
it needs air to change molecularly..

Why are you burning motor oil in a oil burner?

Its quite common, lots of people use waste oil burners, either homemade or commercial to melt metals in a foundry.

Some high MW organic molecule are subject to cracking and decomposition reaction before reaching boiling point...

Are you going to centrifuge it first? it tends to give better results, the local garage has a torpedo heater they run off the waste oil they get. They
have a cheap ebay centrifuge they use first and dont pre heat.
I hang around there on occasion looking for aluminium engine heads etc .
