Mission OS

Typowe problemy

• Burner flame instability or failure to light off cleanly
• Soot deposit buildup on fire-side tube surfaces reducing thermal efficiency
• Water-side scale formation from inadequate feed water treatment
• Refractory cracking or spalling around the burner throat
• Safety valve seat leakage or set pressure drift
• Low water level cutout malfunction
• Fuel oil heater or viscosity control issues when firing HFO

Lista kontrolna przeglądu

• Burner flame pattern and ignition sequence check, including pre-purge
• Safety valve lift and reseat test
• Low-low water level alarm and cutout function test
• Boiler water chemical treatment sampling (alkalinity, phosphate, chlorides)
• Soot blowing effectiveness on fire-side tubes
• Refractory condition at the burner throat
• Water level gauge glass cross-check against remote indication
• Exhaust gas economizer fouling check, if fitted
• Relief and vent valve operation

Zakresy są typowe dla tej klasy konstrukcyjnej. Decydujące są zawsze dokumenty producenta dla danego numeru seryjnego.

Krytyczne części zamienne

• Burner nozzle/atomiser
• Ignition electrodes
• Safety valve spring and seat set
• Water level gauge glass and gaskets
• Low water alarm float or probe
• Refractory repair material for the burner throat

Bezpieczeństwo

• Pressurised steam and hot surfaces throughout the boiler and steam lines
• Boiler damage or explosion risk from a low water condition if the cutouts fail - low water alarm testing is safety-critical
• Fuel oil under pressure and heated to high temperature on HFO firing
• Furnace/combustion chamber explosion risk if the pre-ignition purge sequence is bypassed
• Confined space hazards during internal waterside/fireside inspection

Przegląd klasyfikacyjny

Falls under Continuous Survey Machinery for boilers; class typically requires internal waterside/fireside examination, witnessed safety valve testing, and review of water treatment logs at each boiler survey.

Szacowana trwałość: Composite auxiliary boilers of this size are commonly kept in service in the order of 15-25 years with proper water treatment and periodic tube renewal; actual life depends heavily on water chemistry control and duty cycle, so treat this as an order-of-magnitude figure only.
