Аннотация

This article presents a theoretical study devoted to the gas-phase ignition of dispersed brown coal layer by a metal particle heated to high temperatures (more than 1000 K) in the framework of a mathematical model describing the interrelated processes of coal heating, cooling of a local heating source, thermal decomposition of solid fossil fuel, the yield of volatile fluxes, the formation and heating of a gas mixture, its ignition. The influence of the heating source initial temperature and the depth of its penetration into the coal near-surface layer on the main process characteristic - the ignition delay time - was established. The relationship between the position of the combustion initiation zone in the hot particle neighbourhood and the heating intensity of the gas mixture including the thermal decomposition products of coal and an oxidizer was revealed.
