Q

The water in a steaming auxiliary boiler should be tested daily for __________.

🔍 Key Concepts

• boiler water treatment on ships • difference between feedwater gases and dissolved salts • what causes scale and corrosion in marine boilers

💭 Think About

• Think about which contaminant typically enters a marine auxiliary boiler from seawater leakage or make‑up water, and must be controlled to prevent scale. • Ask yourself which item on the list is commonly checked with a simple onboard chemical test kit as part of routine boiler water treatment. • Consider which of these choices is most directly related to controlling the boiler’s total dissolved solids, rather than being a gas already handled by deaeration or chemical scavengers.

✅ Before You Answer

• Identify which option is a salt from seawater, not a gas. • Recall which parameter is part of standard daily boiler water test kits used by engineers. • Eliminate options that are usually controlled by deaerators or oxygen scavenger chemicals rather than by daily boiler water titration tests.
