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.
Combustion is a type of chemical reaction that usually involves oxygen. For combustion to occur, oxygen combines with another compound to form water and carbon dioxide. Combustion usually results in the production of light and heat in the form of a flame. There are two types of combustion: incomplete and complete combustion. Incomplete combustion is the type of combustion in which there is not enough oxygen or a high enough temperature for the carbon to turn into carbon dioxide.
