The procedures recommended for auxiliary boilers having high salinity include __________.

Question 1 of 27070

The procedures recommended for auxiliary boilers having high salinity include __________.

🔍 Key Concepts

• Boiler water salinity and contamination control in auxiliary (marine) boilers • Purpose of a bottom blow on a boiler and when it is used • Effects of oxygen scavengers, pH, and phosphate treatment on boiler water

💭 Think About

• Ask yourself: if salinity is high, what impurity is entering the boiler, and where does it concentrate? • Which of the listed actions would physically remove contaminated water, and which only change its chemical balance? • In normal boiler water treatment, which chemicals are used to prevent corrosion and scale, and are they intended to correct a sudden salinity spike?

✅ Before You Answer

• Identify which option directly removes dissolved salts from the boiler water rather than just treating them chemically • Recall the primary purpose of a bottom blow valve on a boiler • Verify whether oxygen scavengers, pH adjustment, and phosphate are used for routine conditioning or for correcting contamination events like high salinity
