Can a choked stub pipe cause distortion in emission data from the analyser?

In emission monitoring systems, not every deviation signals a haywire process. Sometimes, it’s the installation accessories themselves that cause distortion in readings. One such issue involves the stub pipe.

The stub pipe is a small but essential component in the analyser installation assembly. It allows the sample gas to be transferred from the stack to the analyser. However, when dust or particulate matter accumulates inside this stub pipe due to improper alignment, it begins to interfere with the sample quality, without triggering immediate alarms. In such cases, even when the process remains unchanged and temperatures are stable, analyser readings (especially the dust output) start drifting, impacting the measurement accuracy. This kind of deviation can result in false high readings, potentially leading to incorrect emissions reporting or even regulatory non-compliance.
