Quick Summary

An oxidizing flame is a flame that has an excess of oxygen, such as the outer cone of a gas flame. In chemistry, oxidation is a process where an atom, ion, or molecule loses electrons. Flames can be used to produce chemical reactions.1234

In a premixed flame, different chemical reactions occur in distinct zones. The outer cone of a flame is oxidizing due to the excess oxygen present. This excess oxygen can lead to the complete oxidation of fuel gases into carbon dioxide and water. Oxidation is a fundamental part of oxidation-reduction (redox) reactions, where the oxidation number of a chemical species changes.53

When a premixed flame burns in open air with an excess of fuel, there appears in addition to the flame zone a zone of diffusion flame; this is accounted for by the diffusion of atmospheric oxygen, as, for example, in the…
