Consider the following statements regarding superheating in Rankine Cycles
1) It reduces the specific steam consumption
2) It increases the dryness fraction of steam at the exhaust for the same value of condenser pressure
3) It reduces the cycle efficiency Of the these statements

Question

Quizplus · Accepted Answer

1) Superheating reduces the specific steam consumption by increasing the average temperature of heat addition, which improves the cycle efficiency. 2) It also increases the dryness fraction of steam at the exhaust for the same value of condenser pressure, reducing moisture content and the potential for turbine blade erosion. Statement 3 is incorrect because superheating actually increases the cycle efficiency, not reduces it.
