🔍 Key Concepts

• Oxygen corrosion in boilers and why dissolved oxygen is harmful to metal surfaces • The role of chemical oxygen scavengers in boiler water treatment • Common chemicals used in marine boiler feedwater systems to remove or bind oxygen

💭 Think About

• Which of these choices are known to react with and remove dissolved oxygen from water rather than disinfect or dry it? • Look at the terms sulfite and hydrazine versus bromine and hygroscopic — which are typically associated with boiler water treatment chemistry? • Think about what you’ve seen in boiler water test logs on ships: which chemicals are actually added to the feed tank to control oxygen corrosion?

✅ Before You Answer

• Verify which option includes chemicals commonly classified as oxygen scavengers in boiler feedwater treatment. • Check whether bromine is normally used for disinfection (killing organisms) rather than for oxygen removal. • Confirm that hygroscopic means a substance that absorbs moisture from the air, and consider if that property alone addresses dissolved oxygen corrosion in a boiler.
