Dynamic 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.
