Investigating Explosive Behaviours of Metal Powder

Regarding this project, the micro size of iron powder had been investigated. Therefore, the problem statement needs to be solved by providing the methods in order to study the behaviour of micro material of metal powder. Explosibility of micron material was determined and compared according to explosion severity and likelihood using standard dust explosion equipment. ASTM methods were followed using a 20L Spherical Explosion Test System. The explosibility parameters investigated for both size ranges of iron include explosion severity (maximum explosion pressure (Pmax) and size-normalized maximum rate of pressure rise (KSt) and explosion likelihood (minimum explosible concentration (MEC), minimum ignition energy (MIE) and minimum ignition temperature (MIT). Iron particle concentration based on different weigh of metal powder. The results show a significant increase in explosion severity as the different concentration show the different severity and explosibility.
