🔍 Key Concepts

• Desuperheater purpose in a high-pressure boiler system • Difference between feedwater flow control and steam temperature control • Location of a desuperheater relative to the steam drum and superheater

💭 Think About

• Ask yourself: Does a desuperheater work on feedwater going into the drum, or on steam that has already left the drum? • Think about what the word "desuperheater" literally means in relation to superheated steam. • Which component in the system is primarily responsible for maintaining essential feedwater flow into the drum?

✅ Before You Answer

• Verify what superheated steam is and where it exists in the boiler cycle. • Confirm whether a desuperheater normally adds heat or removes heat from the steam. • Check whether feedwater regulating valves/pumps or a desuperheater are used to maintain essential flow of feedwater into the drum.
