Abstract:
To study spontaneous combustion and explosion of brown-coal dust, an experimental setup was designed and a method for analysis of these processes was proposed. Kinetic parameters (activation energy and preexponent) of the brown coal from the Irsha–Borodino deposit were determined. It was shown in experiments that, for certain coal/oxidizer ratios, the explosion has a two-stage character. The repeated explosion of dust is caused by thermal activation of coal at the first stage of the explosion. Mathematical models for a qualitative description of spontaneous combustion of brown-coal dust are considered.
Keywords:
