Only Flammables Flashback?

[david6245]

Hello,

I am new to the subject of flame arrestors, and am in need of some fundamental help.

If a gaseous mixture to a flare is not classified as flammable, then is a flame arrestor required? Is flashback only a concern for flammable mixtures? My stream is composed primarily of Nitric Oxide.

Any reference sources would be appreciated.

Thanks,

Flame arresters are for the prevention of flames propagating through the flame arrestor grid into or out of a volume.

Detonation arrestors prevent the propagation of a sonic speed flame front inside a pipe or duct.

Which are you asking about. It sounds to me like the latter but I am not sure.

Yes, I apologize for my confusion. I am asking about detonation arrestors as I understand flame arrestors are only for end of line applications, i.e. not in between a process and a flare as is the case for my application.

Thanks,
