fuel oil flash point

In the United States, it refers to any flammable liquid or liquefiable petroleum product with a flash point of not less than 37.8°C. It can be either residual fuel oil or distillate fuel oil.

I didn’t want to answer you~~ I suspected there was a problem~~ but I want to tell you clearly~~ The book you are looking for is wrong~~ Different types of fuel oil are very different in lightning~~, and may cause production accidents~~ There are relevant books that you can check~~

It's not good for new classmates to do this. It's not Haichuan's purpose to tell others if they know it.
