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] It is distinct from (but has similar practical effects to ...
Jan 9, 2023 · The meaning of SPONTANEOUS COMBUSTION is self-ignition of combustible material through chemical action (such as oxidation) of its constituents —called also spontaneous ignition.
Spontaneous combustion, the outbreak of fire without application of heat from an external source. Spontaneous combustion may occur when combustible matter, such as hay or coal, is stored in bulk. It begins with a slow oxidation process (as bacterial fermentation or atmospheric oxidation) under.

Dec 1, 2016 · Spontaneous combustion or spontaneous ignition, as it is often called, is the occurrence of fire without the application of an external heat source. Due to chemical, biological, or physical processes, combustible materials self-heat to a temperature high enough for ignition to occur. According to the National Fire Protection Association (NFPA ...
Jan 9, 2023 · Spontaneous combustion is a chemical reaction, plain and simple.; The core reaction is oxidation, when materials degrade while exposed to oxygen. The reaction releases heat, and sometimes that ...

Spontaneous combustion often occurs in piles of hydrocarbon-soaked (oily) rags and can constitute a serious fire hazard. Fires started by spontaneous combustion are caused by the following mechanisms: (1) spontaneous heating, (2) pyrophoricity, and (3) hypergolic reactions. Spontaneous heating is the slow oxidation of an element or compound ...
