Combustion is an exothermic
process between a fuel source and
a form of oxygen that produces
heat and light. Sources of fuel can
be in the form of a gas, liquid,
cellulose (wood), metal, or plastic.
Oxygen can be in the form of
gaseous oxygen or combined in the
form of hypochlorites, chlorates,
perchlorates, nitrates, chromates,
oxides, peroxides, or other
The combustion process can be in either a flaming type or a flameless (glow) surface type.
The flaming type of combustion is represented by a tetrahedron. Each side represents one of the four requirements of the tetrahedron, temperature, a form of oxygen, fuel, and an uninhibited chain reaction (very short lived).
