Minimum Ignition Temperature (MIT) - BRE Group
Minimum Ignition Temperature (MIT) The Minimum Ignition Temperature is the lowest temperature of a hot surface which will cause a dust cloud to ignite and propagate flame. The test apparatus and method comply with the IEC Stan-dard 1241-2-1 Part 2 Section 1. The results may be used for DSEAR risk assessments to determine potential ignition sources
Autoignition temperature - Wikipedia
The autoignition temperature or kindling point of a substance is the lowest temperature in which it spontaneously ignites in normal atmosphere without an external source of ignition, such as a flame or spark. This temperature is required to supply the activation energy needed for coustion.The temperature at which a chemical ignites decreases as the pressure or oxygen concentration increases.

Petroleum - Wikipedia
Petroleum (pronounced / p ə ˈ t r oʊ l i ə m /) is a naturally occurring, yellowish-black liquid found in geological formations beneath the Earth''s surface. It is commonly refined into various types of fuels.Components of petroleum are separated using a technique called fractional distillation, i.e. separation of a liquid mixture into fractions differing in boiling point by means of
Coking | » Advances in Delayed Coking
Auto-ignition. The heavy, semi-coked liquid in the drum will have an auto-ignition temperature somewhat above 300°F. This means viscous liquid drained from the coke drum will burst into flame upon exposure to air without any external source of ignition. The coke drum should be cooled below its auto-ignition temperature.
Flash Point - Engineering ToolBox
