Аннотация: The paper presents the results of a study of the process of spontaneous combustion of partially carbonized lignite and sorbent from coal, depending on the particle size. To determine the critical conditions of spontaneous combustion and the effective kinetic parameters of the process proceeding along the thermal mechanism, a speciaПоказать полностьюl experimental setup was used. The results of the study indicate the influence of particle size on the time of spontaneous combustion and on the rate of oxidation of coal matter. A mathematical model of spontaneous combustion of coal matter is developed. The model uses the spatial nonstationary heat conduction equation, in which the heat release in the process of coal oxidation is taken into account by setting a heat source based on the experimentally obtained kinetic parameters of the spontaneous combustion process-effective activation energy and the pre-exponential factor.
