An “Ideal” Mill Inerting System

• Start Mill Inerting System (MIS) sequence – Commence fogging – Cease fogging after 3 to 5 minutes – Begin inerting steam flow at “Normal Inerting Flow” rate (sufficient flow to bring mill environment down to 14% O 2 within 2 minutes) – Once “Inert Status” is attained, automatically reduce inerting steam flow to “Inerting

Inerting system - Wikipedia

An inerting system decreases the probability of combustion of flammable materials stored in a confined space, especially a fuel tank, by maintaining a chemically non-reactive or "inert" gas, such as nitrogen, in such a space. "Inerted" fuel tanks may be used on land, or aboard ships or aircraft

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.
