Abstract

The experimental procedure is presented for range test of critical flame spread in the conditions of uniform distribution of particles in dust cloud under varied temperature of the ignition initiation source. Fire and explosion hazard of coal dust is estimated by the method of successive approximations. The feasibility of studying the cold flame effect in inflammation of coal dust suspension in air and its transition to the hot mode burning when dust concentration grows is demonstrated, which is of importance for the theory of safety technology.
