An inerting system decreases the probability of combustion of flammable materials stored in a confined space. The most common such system is a fuel tank containing a combustible liquid, such as gasoline, diesel fuel, aviation fuel, jet fuel, or rocket being fully filled, and during use, there is a space above the fuel, called the ullage, that contains evaporated fuel mixed ...

In normal operation inerting occurs by using the exhaust of the rotary kiln or from hot gas generated during the operation of the coal mill plant. In case of an emergency shutdown, the coal mill plant inert gas is injected. LOC and MAOC. The goal at all times is to reduce the limiting O 2 concentration (LOC) so that explosions can no longer ...

Abstract. 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.
