Premixed flame

Different flame types of a Bunsen burner depend on oxygen supply. On the left a rich fuel mixture with no premixed oxygen produces a yellow sooty diffusion flame, and on the right a lean fully oxygen premixed flame produces no soot and the flame color is produced by molecular radical band emission.

A premixed flame is a flame in which the oxidizer has been mixed with the fuel before it reaches the flame front. This creates a thin flame front as all of the reactants are readily available. If the mixture is rich, a diffusion flame will generally be found farther downstream.
