🔍 Key Concepts

• Superheated vs. desuperheated steam and how temperature is controlled in a boiler system • Function and location of a spray attemperator in the steam line • Where in the system steam is most likely to be at or near saturation temperature

💭 Think About

• Which component is specifically designed to reduce steam temperature from superheated toward saturation by adding water? • At which point would you expect steam to be the hottest and most superheated, and at which point would it be a bit cooler but still above saturation? • Look at the purpose of each listed valve or chest: are they primarily for flow control/stop, or for temperature control?

✅ Before You Answer

• Identify which choice is directly associated with temperature control rather than just stopping/controlling flow • Recall that desuperheated steam is still slightly superheated but close to saturation, usually just downstream of a cooling/tempering device • Eliminate any locations that are typically where maximum superheat is maintained (upstream of temperature‑reducing devices)
