🔍 Key Concepts

• Function of a spray attemperator in a steam system • Relationship between steam temperature and pressure in boilers and turbines • Where deaeration and aeration normally occur in a marine steam plant

💭 Think About

• Think about what part of the steam cycle a spray attemperator is installed in: on the steam line, the condensate line, or the feed/makeup line? • Does a spray attemperator add or remove non‑condensable gases, or does it change a thermodynamic property such as temperature? • Which component in a steam plant is normally used to remove dissolved gases (like oxygen) from condensate or feedwater?

✅ Before You Answer

• Identify whether a spray attemperator deals with steam or water treatment (gases in water vs temperature of steam). • Recall which piece of equipment is typically used to deaerate condensate (name that component and compare its function). • Confirm if an inter condenser is part of a vacuum/condensing system and whether that is where spray attemperators are usually found.
