Abstract

In order to design an Oxygen Reduction System (ORS) the most important parameter is the limiting oxygen concentration (LOC). Currently there are a couple of different small scale test methods used to determine the LOC for specific materials. In small scale tests an external heat flux is applied, to account for parameters such as geometry that otherwise cannot be replicated, theoretically arriving at a sufficiently low LOC. Other methods have tried to take heat transfer and geometry into consideration to better replicate real world conditions. However, there are some discussions into the validity to some of these existing methods. To replicate real world conditions a large scale setup was designed and used to determine LOC for certain...

In order to design an Oxygen Reduction System (ORS) the most important parameter is the limiting oxygen concentration (LOC). Currently there are a couple of different small scale test methods used to determine the LOC for specific materials. In small scale tests an external heat flux is applied, to account for parameters such as geometry that otherwise cannot be replicated, theoretically arriving at a sufficiently low LOC. Other methods have tried to take heat transfer and geometry into consideration to better replicate real world conditions. However, there are some discussions into the validity to some of these existing methods. To replicate real world conditions a large scale setup was designed and used to determine LOC for certain warehouse configurations. This large scale setup is costly to run and therefore there is a need to investigate the possibility of creating an intermediate scale setup that has the ability to make flame propagation assessments for varying fuels, geometries and ignition sources. In this paper a first attempt for an intermediate scale setup is examined, and preliminary findings are discussed.
