| چکیده | ||
| در این مقاله، سیکل ترکیبی توربین گاز رآکتور هلیوم با سیکل رانکین آلی از دیدگاه تحلیل اگزرژی متداول و پیشرفته مورد مطالعه و مقایسه قرار گرفته است. با استفاده از نرم افزار حل معادلات مهندسی مدل‌سازی این سیکل انجام گرفته و نتایج تحلیل انرژی و اگزرژی متداول به دست آمده است. سپس به منظور تعیین اولویت‌بندی مناسب بهبود اجزاء سیکل از دیدگاه تحلیل اگزرژی پیشرفته مورد مطالعه قرار گرفته است. در واقع تحلیل اگزرژی پیشرفته با تقسیم نابودی اگزرژی هر جزء به بخش‌های درونزا، برونزا، اجتناب‌پذیر و اجتناب‌ناپذیر، اطلاعات دقیقی در مورد پتانسیل بهبود واقعی عملکرد سیستم ارائه می‌دهد. نتایج تجزیه و تحلیل اگزرژی پیشرفته نشان می‌دهد که با اصلاح و ارتقای اجزای سیستم مورد مطالعه در این پژوهش، 19/1 درصد از نابودی اگزرژی کل سیستم قابل کاهش می‌باشد. همچنین تجزیه و تحلیل اگزرژی پیشرفته با در نظر گرفتن بخش اجتناب‌پذیر درونزا در هر جزء اولویت بهبود را به ترتیب به کمپرسور و سپس به رآکتور و توربین گازی می‌دهد. این در حالی است که از تجزیه و تحلیل اگزرژی متداول، نابودی اگزرژی محاسبه شده برای رآکتور بیشتر از کمپرسور بوده و اولویت بهبود با رآکتور است. علاوه بر آن براساس اولویت‌بندی تحلیل اگزرژی پیشرفته امکان افزایش بازده اگزرژی سیکل از 75/21% به 82/51 % و بازده انرژی سیکل از 51% به 56/22 % وجود دارد. | ||

| چکیده [English] | ||
| In this work, the combined cycle of a helium reactor gas turbine with an organic Rankine cycle is studied and compared from the perspective of conventional and advanced exergy analysis. Using Equation solving engineering software, modeling of this cycle has been done and the results of conventional energy and exergy analysis have been obtained. Then, to determine the appropriate prioritization of cycle component improvement from the perspective of advanced exergy analysis has been studied. In fact, advanced exergy analysis provides accurate information about the real potential for system performance improvement by dividing the exergy destruction of each component into endogenous, exogenous, avoidable, and unavoidable components. The results of advanced exergy analysis show that by modifying and upgrading the components of the system, 19.1% of the total exergy destruction of the system can be reduced. According to the advanced exergy analysis, the improvement priority belongs to the compressor and then to the reactor and gas turbine. However, from the conventional exergy analysis, the reactor's exergy destruction is greater than that of the compressor and the priority is on the reactor. In addition, based on the prioritization of advanced exergy analysis, it is possible to increase the cycle exergy efficiency from 75.21% to 82.51% and the cycle energy efficiency from 51% to 56.22%. | ||
