Abstract
The temperature distribution in a cylindrical deposit of combustible dust placed in hot environments is described by a differential equation according to the thermal theory. From the equation, the self-ignition temperature and the induction time to ignition have been determined in this paper by computer simulation, by varying the size of the cork dust deposit. The calculated results become straight lines on a log-log paper plotted against the deposit volume, and were in good agreement with the experimental data currently reported by Leuschke. Hence, it can be concluded that the simulation is usable in predicting self-ignition hazards in the storage and handling processes of fine particles.
