Boiler component: device that raises the temperature of saturated steam at constant pressure Name the component used to heat saturated steam further without increasing its pressure. Choose the correct component.

Difficulty: Easy

Blow-off cock
Fusible plug
Superheater
Stop valve

Correct Answer: Superheater

Explanation:

Concept

A superheater adds sensible heat to saturated steam at (approximately) constant pressure to produce superheated steam.

Why others are incorrect

Blow-off cock: used to remove sludge and lower water level.
Fusible plug: safety against low-water overheating.
Stop valve: isolates/controls steam flow.

Final Answer
Superheater.
