🔍 Key Concepts

• Steam temperature control in marine boilers • Difference between saturated steam and superheated steam • What happens when you spray water into a steam line

💭 Think About

• Think about what a desuperheater actually does to steam temperature and quality: does it raise or lower the temperature? • If you add a small amount of water to very hot dry steam, what happens to its temperature and moisture content? • Which option sounds like fine "control" of steam conditions versus an extreme or absolute change?

✅ Before You Answer

• Clarify the meaning of superheated steam vs saturated steam • Decide whether a desuperheater is meant to totally eliminate superheat or just reduce it to a controlled level • Consider whether the device’s main function is to protect equipment, change efficiency, or adjust steam moisture/temperature
