Emergency inerting systems for coalgrinding applications
In the case of coalgrinding or storage (as one might find in a cement plant) it is not possible to remove the fuel (coal) or ignition source (grinding energy, heat, static charges) and so one has to concentrate on removing the third necessary component O 2 This fact has given rise to inerting systems that rely on the use of inert gases
