Abstract
In studying lifted diffusion flames in the transitional regime from laminar to turbulent combustion, structures with a reduced intensity of own luminescence and a clearly expressed contour are observed in the combustion front. The emergence of such structures in the flame has a spontaneous character and may occur at significant distances from the ignition points (region of lifted flame stabilization).
