Spontaneous combustion. 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.
The combustion process begins when a fuel source is heated beyond its ignition temperature in the presence of an oxidant, with this molecular energy creating a self-sustaining chemical chain reaction of radicals when the energy it produces is greater than or equal to the energy needed for continued burning.
