Abstract: The kinetics of the spontaneous combustion of sawdust was investigated with the use of the Ya. S. Kiselyov thermal theory by means of the temperature-variation method. The cooling parameter characterizing the heat dissipation conditions of the spontaneously igniting mass has been determined. Activation energy, preexponential factor of the process of oxidation of sawdust and critical parameters of the raw materials being investigated that allow forecasting the conditions of their fire-explosion safe storage have been calculated.

Keywords: sawdust, spontaneous combustion, adiabatic self-heating velocity, rate of cooling, activation energy, preexponential factor, critical parameters.
