Question
Which one of the following modifications of the simple ideal Rankine cycle increases the thermal efficiency and reduces the moisture content of the steam at the turbine outlet?
Options :
Decreasing the condenser pressure.
Increasing the boiler pressure.
Decreasing the boiler pressure.
Increasing the turbine inlet temperature
Answer :
Increasing the turbine inlet temperature
Solution :
Due to increase of the turbine inlet temperature, quality of the stream at outlet of the turbine improves. Which increases the thermal efficiency and reduces the moisture content of the steam at the turbine outlet.
