Q

Desuperheated steam from the control desuperheater is returned to the main superheater to control the outlet temperature by the action of __________.

🔍 Key Concepts

• Superheater temperature control methods in marine boilers • How desuperheaters work to reduce steam temperature by water injection • Which component in a control loop actually modulates flow to change temperature

💭 Think About

• In a typical automatic temperature control loop, which part physically changes the amount of desuperheated steam or spray water to adjust outlet temperature? • Look at each option and ask: is this a general flow device, a pressure device, or a temperature‑control device? Which one normally responds directly to temperature changes? • Consider how the control desuperheater interacts with the main superheater: what is being adjusted—temperature, pressure, or simple on/off flow?

✅ Before You Answer

• Identify which option directly references temperature control, not just flow or pressure • Ask yourself which device is commonly paired with a temperature-sensing element in boiler superheat control systems • Eliminate any option that mainly controls pressure rather than temperature
