Common issues

• Data quality note: the manufacturer on file (Furuno Electric Co., Ltd., known for marine navigation/communication electronics, not boilers) does not match the stated product type (Auxiliary Boiler, Oil-Fired). The identity of this specific unit could not be confirmed from the available data - the points below are bauart-typical for oil-fired auxiliary boilers in general and must be verified against the actual manufacturer's manual before use.
• Burner flame failure or ignition faults from fuel nozzle fouling or atomiser wear
• Water-side scale build-up reducing heat transfer and raising tube metal temperature
• Fuel oil contamination or water in fuel causing burner trips
• Safety valve seat leakage or failure to lift at set pressure
• Low water level cut-out or control failure
• Soot deposits on fire-side tube surfaces from incomplete combustion
• Refractory brickwork/insulation degradation around the burner throat

Inspection checklist

• Confirm actual manufacturer and model before relying on any manufacturer-specific figures
• Test safety valve lift and reseat pressure
• Verify low-water and high-water level alarms and cut-outs function correctly
• Inspect burner, atomiser and ignition electrodes; check flame scanner response
• Check water-side for scale via inspection openings where accessible
• Verify fuel oil filters and heaters (if fitted) are clean and functioning
• Check pressure gauge and safety valve test/calibration dates
• Review boiler log for abnormal cycling or repeated trips

Service intervals

Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.

Critical spares

• Burner nozzle/atomiser
• Ignition electrodes
• Flame scanner/photocell
• Safety valve seat/spring set (matched to the actual model once confirmed)
• Water level control/probe set

Safety

• Low-water condition can cause overheating and catastrophic tube/shell failure - level controls and their alarms are safety-critical
• Hot surfaces and pressurised steam/water
• Fuel oil fire risk at the burner front
• Safety valve must never be gagged or its set pressure altered without proper authority

Class survey

Boilers are Continuous Survey Machinery items with annual and intermediate internal/external examinations plus periodic safety valve testing. Given the manufacturer/product mismatch noted above, this entry should be checked against the underlying DNV certificate (MERD00002CD) before any of this content is used for planning.

Estimated lifetime: Cannot be stated reliably given the unresolved manufacturer/model identity of this listing - do not use a generic figure for planning; confirm the actual unit first.
