  2. Autoignition temperature - Wikipedia

    en.wikipedia.org/wiki/Autoignition_temperature

    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. [1]

  3. Char cloth - Wikipedia

    en.wikipedia.org/wiki/Char_cloth

    Char cloth, also called char paper, is a material with low ignition temperature, used as tinder when lighting a fire. It is the main component in a tinderbox.It is a small swatch of fabric made from a natural fibre (such as linen, cotton, jute etc.) that has been converted through pyrolysis.

  4. Flashover - Wikipedia

    en.wikipedia.org/wiki/Flashover

    "Rollover" or tongues of fire appear (known as "angel fingers" to firefighters) as gases reach their auto-ignition temperatures. There is a rapid build-up (or "spike") in temperature due to the compound effect of rapidly burning (i.e., deflagrating) gases and the thermal cycle they produce. This is generally the best indication of a flashover. [2]

  5. Flash point - Wikipedia

    en.wikipedia.org/wiki/Flash_point

    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.

  6. Fire point - Wikipedia

    en.wikipedia.org/wiki/Fire_point

    The fire point, or combustion point, of a fuel is the lowest temperature at which the liquid fuel will continue to burn for at least five seconds after ignition by an open flame of standard dimension. [1] At the flash point, a lower temperature, a substance will ignite briefly, but vapour might not be produced at a rate to sustain the fire ...

  7. Thermite - Wikipedia

    en.wikipedia.org/wiki/Thermite

    Although the reactants are stable at room temperature, they burn with an extremely intense exothermic reaction when they are heated to ignition temperature. The products emerge as liquids due to the high temperatures reached (up to 2500 °C (4532°F) with iron(III) oxide)—although the actual temperature reached depends on how quickly heat can ...

  8. Acetone - Wikipedia

    en.wikipedia.org/wiki/Acetone

    Acetone's auto-ignition temperature is the relatively high 465 °C (869 °F); [19] moreover, auto-ignition temperature depends upon experimental conditions, such as exposure time, and has been quoted as high as 535 °C. [80]

  9. Oxyhydrogen - Wikipedia

    en.wikipedia.org/wiki/Oxyhydrogen

    Oxyhydrogen will combust when brought to its autoignition temperature. For the stoichiometric mixture in air, at normal atmospheric pressure, autoignition occurs at about 570 °C (1065 °F). [4] The minimum energy required to ignite such a mixture, at lower temperatures, with a spark is about 20 microjoules. [4]
