Mill. During mill shut down, the same inerting process starts when the coal feeder is stopped or mill coal inventory reaches a certain level. The inerting process is recommended to continue until the mill is fully stripped of coal. When tripped, a mill shall be inerted and maintained under an inert atmosphere.This guideline may be adapted to fit the needs of most plants and is intended to cover recommended methods of coal handling from offloading facilities up to transfer of the coal to the silo bunker.
