Boiler and Condenser Pressure

In the previous lesson, we learned that increasing the boiler pressure and decreasing the condenser pressure increases the net work output and the

thermal efficiency

of the

ideal Rankine Vapor Power Cycle

The main problem with this method is that the quality of the turbine effluent decreases sharply leading to increased wear or damage to the turbine rotor.
The six methods we will study in this lesson address this problem.
