🔍 Key Concepts

• Role of a deaerator in a marine boiler feed system • Effects of dissolved oxygen and gases in high‑pressure boilers • Typical causes of cavitation, corrosion, and vacuum loss in steam systems

💭 Think About

• Which specific problem is most directly caused by oxygen and other dissolved gases in feed water when it enters a hot, high‑pressure boiler? • Does cavitation in a pump primarily come from dissolved gases in the water, or from low pressure at the pump inlet? • Is loss of system vacuum in a condenser mainly related to feedwater quality, or to air leaks/steam side issues?

✅ Before You Answer

• Match the function: Deaeration = removing dissolved gases (especially oxygen and CO₂) – which option best connects to that function? • Ask: which choice is the primary design purpose of a feedwater deaerator in boiler practice? • Eliminate any options that describe problems not mainly controlled by removing dissolved gases from feed water.
