Experimental Mine "Barbara" of Central Mining Institute, ul. Podelska 72, 43-190 Mikolow, Poland

In real conditions the surface temperature of an equipment enclosure covered with a combustible dust layer can significantly rise due to insulating properties of the dust layer. To assess this effect the measurements of minimum ignition temperature of dust layer at constant temperature of the heated surface (standard method) and the same ignition temperature at constant rate of heat generation were made.
