The Relationship

In order to study the feasible floating roof tank lighting protection technology, this paper put forward making oxygen concentration remain below 8% through inerting sealed space, thus reduces fire risk. By analyzing the oxygen concentration change after injecting nitrogen into the sealed space, sets up the relationship between the oxygen concentration change and nitrogen injection volume. Mean while, through the experiment when the sealed space maintains the micro positive pressure, established a formula about the nitrogen flow and micro positive pressure, which can obtain nitrogen amount directly under different wind velocity and lightning time to complete inerting. Finally, design a nitrogen protection system which can protect lighting fire, and can put out floating roof tanks initial fire.
