🔍 Key Concepts

• Boiler water treatment – what are engineers trying to prevent inside the boiler (scale vs. corrosion)? • Difference between hardness (calcium/magnesium salts) and salinity (chlorides from seawater leakage). • Typical daily tests done on auxiliary boiler water: alkalinity plus one other key indicator of contamination.

💭 Think About

• Which of the choices would show that seawater or salt contamination is entering the boiler and could cause scale or foaming? • Is nitrogen or CO₂ usually measured directly in routine shipboard boiler tests, or are more basic contamination indicators used? • How is hardness normally introduced on a ship – from fresh water make‑up or from seawater leakage through condensers? Which related ion is easiest and most common to test for on board?

✅ Before You Answer

• Ask: Which parameter, when it gets too high, clearly indicates salt (seawater) contamination in the boiler water? • Consider typical shipboard test kits: they almost always include tests for pH/alkalinity and which other simple ion test? • Eliminate options that are not commonly tested daily on small/auxiliary marine boilers.
