Using the Siwek 20 L spherical explosion vessel, the explosion properties have been examined to understand the influence of magnesium content in Mg-Al alloy dusts with different concentration. For this purpose, the Mg-Al alloy dusts (volume mean diameter : ) with magnesium content ratio were used. As the results, the increase of Mg content in Mg-Al alloy causes an decreased minimum explosion concentration and an increased maximum explosion pressure. Also the maximum explosion pressure and maximum rate of pressure rise in Mg-Al alloy dusts mainly depended on the dust concentrations. However, for the explosion index (Kst) of Mg-Al (40:60 wt%), Mg-Al (50:50 wt%) and Mg-Al (60:40 wt%), it was founded to increase the Kst with increasing of magnesium content ratio. |
