The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.

Paper is most likely closer to pine auto-ignition. 71.197.77.252 05:23, 10 April 2015 (UTC) The fact that the autoignition point of paper popularized from Fahrenheit 451 is incorrect. The actual autoignition temperature is 450 degrees Celsius, about 842 degrees Fahrenheit.
Flashover occurs when the majority of the exposed surfaces in a space are heated to their autoignition temperature and emit flammable gases (see also flash point). Flashover normally occurs at 500 °C (932 °F) or 590 °C (1,100 °F) for ordinary combustibles and an incident heat flux at floor level of 20 kilowatts per square metre (2.5 hp/sq ft).
Fat Quality Smoke point [caution 1]; Almond oil: 221 °C: 430 °F [1]: Avocado oil: Refined: 271 °C: 520 °F [2] [3]: Avocado oil: Unrefined: 250 °C: 482 °F [4]: Beef tallow: 250 °C: 480 °F
The flash point of a material is the "lowest liquid temperature at which, under certain standardized conditions, a liquid gives off vapours in a quantity such as to be capable of forming an ignitable vapour/air mixture". [1] The flash point is sometimes confused with the autoignition temperature, the temperature that causes spontaneous ignition.
Methanol (also called methyl alcohol and wood spirit, amongst other names) is an organic chemical compound and the simplest aliphatic alcohol, with the chemical formula C H 3 OH (a methyl group linked to a hydroxyl group, often abbreviated as MeOH).
A large compost pile can spontaneously combust if improperly managed. Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition. [1]
Because pyrolysis takes place at high temperatures which exceed the autoignition temperature of the produced gases, an explosion risk exists if oxygen is present. To control the temperature of pyrolysis systems careful temperature control is needed and can be accomplished with an open source pyrolysis controller. [ 18 ]
