Failure modes to watch for
Every guide in the Vogt Power Vogt-Nemag library lists the candidate root causes its procedure rules out. These are the distinct failure modes we've documented so far, a useful starting point if you don't yet know which specific alarm or symptom you're chasing.
BMS permissive not satisfied (purge not complete, oxygen in flue gas too low, fan not proven)
Faulty igniter plug or damaged igniter cable causing no spark
Fuel gas pressure below the minimum pressure switch setpoint
UV or IR flame detector contaminated or failed, not confirming a flame that is actually present
Flow-accelerated corrosion (FAC) on economizer or LP evaporator tubes, especially at elbows with high fluid velocity
Thermal fatigue cracking at the tube-to-header weld from thermal cycling during frequent starts and stops
Under-deposit corrosion from poor feedwater chemistry allowing oxygen or iron to deposit
Erosion at tube support contacts from steam or gas velocity vibration
Tools you'll need most
These tools are referenced most often across the Vogt Power Vogt-Nemag troubleshooting guides. If you service this equipment regularly, keep them on the cart.

How to diagnose duct burner ignition failure on a Vogt Power Vogt-Nemag HRSG
Duct burner ignition failure is usually a BMS permissive not met, a failed igniter, or low fuel gas pressure. Check the BMS permissive list first before touching the burner hardware.
How to stabilize HP drum level control on a Vogt Power Vogt-Nemag HRSG
Drum level hunting is nearly always a control loop tuning issue or a faulty drum-level transmitter. Check shrink/swell behavior during load changes and re-tune the three-element control loop.
How to detect and respond to an HRSG tube leak on a Vogt Power Vogt-Nemag
Increasing feedwater makeup is the earliest indicator of an HRSG tube leak. Confirm with an acoustic survey or infrared thermography from outside the casing. The unit must be shut down for any tube repair.
