The term autoignition should be nderstood not only as self-ignition, the ignition of a substance but as a complex, spontaneously occurring process, from the first moment of temperature rise (self-heating temperature) to reaching autoignition temperature, as a result of chemical, physical or biological processes. The result of the self-ignition process is the ignition and subsequent burning of the substance or material in a flameless or flameless manner (smouldering, incandescence). Thermal spontaneous combustion is among the most common cases of physicochemical spontaneous combustion. Thermal autoignition is a thermooxidation process that is anifested by burning (flame or flameless) after previous self-heating of substances that are heated to a temperature at which the released heat of reaction exceeds the amount and speed of heat removed to the environment.skhttp://creativecommons.org/licenses/by/4.0/self-ignitionspontaneous ignitionthermal spontaneous combustionspontaneous combustion hexagonfactors of thermal autoignitionArticlehttps://doi.org/10.26552/krm.C.2023.2.5-12
