The newly-built power plants work optimally at their design conditions; however, by aging, they often deviate from those conditions. Therefore, new optimal conditions are required to be determined for them. In this study, invoking a Predictive Model, the impact of different configurations of the feedwater heaters on the performance of the power plant is examined. It is shown that there are optimal values for the pressure of closed feedwater heaters. Following the optimization procedure of Conjugate Directions Method, the optimal pressures for bleeding off steam for all the closed feedwater heaters and the deaerator are achieved, simultaneously. The multi-variable optimization is carried out based on the maximal energy and exergy efficiencies as well as the maximal net delivered power of the cycle. � 2022 The Author(s) Final 2023-05-29T09:36:15Z 2023-05-29T09:36:15Z 2022 Article 10.1016/j.egyr.2022.01.072 2-s2.0-85123731648 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85123731648&doi=10.1016%2fj.egyr.2022.01.072&partnerID=40&md5=83512f553c1df3c6126d72af79d5646c https://irepository.uniten.edu.my/handle/123456789/26707 8 2179 2199 All Open Access, Gold Elsevier Ltd Scopus |
