In Fig. 6, the optimal regenerator pressure for steam extraction as function of condenser pressure is determined through sensitivity analysis. The results in this work show that for optimal perfor- mance steam should be extracted at a lower pressure for feed- water heating when condenser pressure is reduced. In addition, since lower temperature differences exist in the condenser when its pressure is reduced, less exergy is dumped into the environment at a lower condenser pressure. This results in an increase in overall performance. The exergy efficiency and degree of thermodynamic perfection of the power plant increases by 25% and 5%, respectively, when the condenser pressure is reduced from 50 kPa to 25 kPa.
