The explosion risk assessment carried out at the cement plant indicated that appropriate measures were needed to protect the technological equipment and to contribute to reducing the level of risk. Explosive safety workCoal Pulverization System: Explosion Prevention and,,The explosion characteristics are shown in Table 1. The ignition energy of the coal powder is 50mJ, so electrostatic and mechanic sparks should be considered as ignition sources. The explosion index K max is less than 10 MPa.m/s, so venting and suppression are effective for the coal powder. Table 1: Explosion characteristics of the coal powderDynamic steam inerting system for a ball tube mill,,Coal pulverizing system explosions during the last few years have pointed to the need of developing inerting systems for preventing such incidents. The greater use of western subbituminous coals (with their higher tendency for spontaneous ignition) is a contributing factor to the increased frequency of coal pulverizer explosions.
