Failure modes to watch for
Every guide in the ANDRITZ ANDRITZ HERB 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.
Carryover of sodium and potassium salts from the furnace depositing on tube surfaces
Insufficient sootblowing frequency during high-solids firing periods
Reduced steam-side velocity from low-load operation allowing deposits to accumulate
Plugged sootblower nozzle reducing effectiveness of cleaning cycles
Solidified smelt bridging the spout opening during low-load operation
Reduced wash water flow allowing smelt to freeze at the spout tip
Scale or char accumulation narrowing the spout bore over time
Draft imbalance causing localized cooling at the spout

How to inspect for lower furnace corrosion on an ANDRITZ HERB Recovery Boiler
Lower furnace corrosion typically appears as thinning or pitting on waterwall tubes. Inspect with UT thickness gauging during planned outages and trend wall thickness over time.
How to clear a smelt spout blockage on an ANDRITZ HERB Recovery Boiler
Smelt spout blockage stops flow and risks a dangerous water contact. Shut off wash water, clear the blockage mechanically, then restore wash water before resuming operation.
How to diagnose superheater tube fouling on an ANDRITZ HERB Recovery Boiler
Fouled superheater tubes raise flue-gas exit temperature and reduce steam output. Confirm by comparing exit temperature trend to baseline, then schedule sootblowing or offline cleaning.
