🔍 Key Concepts

• Superheater function in a steam plant and what happens if steam temperature gets too high • Purpose of safety valves in any pressure/temperature system • Difference between a superheater and a desuperheater

💭 Think About

• Ask yourself: Which component (superheater or desuperheater) is directly exposed to the highest steam temperatures and needs protection from overheating? • What is the primary job of a safety valve: to control flow rate, or to relieve excess pressure/temperature to protect equipment? • Which of the options sounds like normal flow-control/operating function rather than an emergency protective function?

✅ Before You Answer

• Be clear on the definitions of superheater vs desuperheater • Remember that safety valves are primarily protective devices, not flow‑regulating devices • Eliminate any choices that describe routine control of steam flow rather than emergency protection from dangerous conditions
