Yokogawa GC1000 FlameOut Problem

[Ayoob.M]

Dear all
I want to know about the effect of Air purifier(Zero Air Generator) malfunction on FPD Flame.

I am working on a Yokogawa GC1000 with FPD sensor for H2S in natural gas online monitoring.
I have checked the flow rate of H2, sample and air and they are all correct according to documents. The problem is when the ignition happens I can see the thermocouple signal rises and after ignition, flame out occur.
The only major fault I found was in air purifier(zero air generator) which is a catalytic type with electrical heat tracing. Its electrical coil for heat tracing is not working and its catalyst life time is finished. I have ordered a new one.
I wonder if the malfunction of air purifier is the main reason of flame out after ignition.

Wish to know about your experiences
Regards

I have no experience with FPD, but in my opinion zero air generator has no impact on extinguishing of the flame. Your GC should work even without zero air generator.
