🔍 Key Concepts

• Superheated steam vs. saturated steam – know the difference in temperature and moisture content • What a desuperheater does in a steam system (where it’s located and how it works) • How controlling superheater outlet temperature protects turbine/engine components

💭 Think About

• Which choices talk about controlling the temperature of superheated steam, and which talk about saturated steam? • What does adding a small amount of water to very hot, dry steam actually do to its temperature and moisture content? • Is it realistic for any device to keep steam flow constant under all load conditions, or is that wording suspicious?

✅ Before You Answer

• Identify which options correctly use the terms superheated steam and saturated steam • Ask: does a control desuperheater mainly affect temperature or flow volume? • Consider whether a control desuperheater’s job is to cool superheated steam or to heat saturated steam
