Аннотация: The effect of mechanically activated coal grinding on the time of their ignition in a vertical tubular reactor is studied experimentally and numerically. The experiments showed that coal, ground by an activator mill (disintegrator mill), ignites faster due to the effect of mechanical activation. According to numerical calculation oПоказать полностьюf the processes of ignition and combustion of mechanically activated pulverized coal fuel, it is clear that the use of non-stationary methods for turbulence simulation and a model of the volatile yield, taking into account the structure of coal matter, allow an estimate of the contribution of mechanically activated grinding to the intensity of devolatilization. © 2020, E.B.
