Fire is described as the visible result of an oxidation process in the chemical reaction known as combustion. Combustion occurs between an oxidant (source of fuel) and oxygen which results in the release of heat and the source of fuel being converted into another form (Grimwood et al., 2010). When heat is released, light is produced either as a flame or glowing. The fuels which bring about combustion are mainly organic compounds like hydrocarbons which may be in the solid, liquid, or gaseous phase.
The part of the fire which is visible is known as the
