The flame detection signal for the spent acid pyrolysis project is abnormal
Thread Content
The new waste acid pyrolysis project installed in our factory not only handles waste acid but also processes acidic gases from methanol. Recently, when the volume of these acidic gases exceeded 200 cubic meters, the flame detection signal turned red. Only the interlock can be removed. But this is very dangerous; let’s discuss it together.
It works normally when only natural gas is used, but it starts to flicker as soon as acidic gas is introduced; it seems that the design of the air inlet is inadequate. Running with the interlocking disabled now feels really dangerous
Previously, the flame detection signals were typically set for fuel gas conditions; when switching to acidic gas, it is generally necessary to adjust these flame detection signals again, but this task must be carried out by the supplier.
We encountered the same problem: when only acidic gas (35% H2S, with the rest being mainly CO2) was burned, neither of the two flame detectors lit up. How did you eventually solve this issue?

I haven’t logged in for a long time; currently we mainly burn natural gas, with little acidic gas being used. Which company are you from?
Thank you, I haven’t logged in for a long time. For now, we still only use waste sulfuric acid
