WebNot to be confused with Inerting (gas). In fire and explosion prevention engineering, purging refers to the introduction of an inert (i.e. non-combustible) purge gas into a closed system (e.g. a container or a process vessel) to prevent the formation of an ignitable atmosphere. Web21 okt. 2011 · The necessary inert gas capacity is calculated according to geometrical volumes of all components to be inerted. Calculation is based on the total geometrical volume of the coal grinding system (75% of silo net volume in case of two or more silos). High-pressure CO2 inerting systems
