Flash point: The temperature at which a liquid fuel begins to burn when heated. (Error) Flash point: When fuel oil is heated to a certain temperature, the components with lower molecular weights and lower boiling points will vaporize and escape from the surface of the oil first, forming oil vapors. As the oil temperature rises, more oil vapor is produced, and the concentration of oil vapor near the oil surface increases. At this point, in the presence of an external ignition source, a flash fire occurs on the oil surface (lasting no more than 5 seconds), but it does not result in sustained combustion ；
That’s wrong, right? Isn’t it called the ignition point?
