Ignition critical conditions and time-to-ignition for a methane–air mixture

Combustion and ignition processes are considered from the standpoint of the theory of thermal ignition and reaction kinetics. An analytical solution of the problem of thermal hotspot ignition was obtained to describe the ignition processes reactive gas mixtures. As a result of this solutions, the critical conditions and the ignition induction time were determined. A solution of the problem of ignition of a methane–air mixture characteristic of the conditions of mine workings.
