Abstract

The phenomenon indicated in the title was qualitatively investigated using the approximate theory of flame propagation velocity. It was concluded that the equation of the second ignition limit for a spatially homogeneous problem is also qualitatively valid for inhomogeneous ignition, which is the occurrence of a local active ignition center on the most chemically active site of the surface and the subsequent propagation of flame from this center.
