The purpose of a superheater in a steam plant is to:
- ACool the steam before it enters the turbine
- BRaise steam temperature above saturation, removing moisture✓ Correct
- CIncrease the boiler water level
- DReduce the boiler pressure
Explanation
A superheater adds heat to saturated steam, raising its temperature above the saturation point. Dry, superheated steam improves efficiency and prevents condensation/erosion in the turbine.
