Abstract
Atık ısı geri kazanımının önemli bir rol oynadığı gelecekteki enerji talebi ve çevre kirliliği sorunlarının hesaplanmasında verimlilik çoğu zaman birincil faktördür. Organik Rankine çevrimi (ORC), düşük ile orta dereceli atık ısı kaynakları için teknik uyumluluk, fizibilite ve güvenilirlik nedeniyle araştırmacıların ve/veya üreticinin yaygın ilgisini çekmeye devam etmektedir. Bu makale, enerji ve ekserji kavramlarına dayalı olarak baca gazı destekli organik Rankine çevrimleri üzerine optimizasyon analizi sunmaktadır. Bu çalışmada, termal enerjiyi elektrik ve/veya mekanik enerjiye dönüştürmek için iki türbinli çevrim kullanılarak Taguchi metodu ile optimizasyon çalışması yapılmıştır. Optimizasyon çalışması için parametreler, türbin giriş basıncı P1, çevrim ara basıncı P2 ve türbinden ara basınçtaki isı eşanjörüne aktarılan akışkan oranı PC3 olarak seçilmiştir. Elde edilen sonuçlara göre ORC çevriminin birinci ve ikinci kanun verimleri üzerinde en etkili parametrenin türbin giriş basıncı (1. kanun için %70.23, 2. kanun için %72.38) olduğu tespit edilmiştir.

Abstract
Efficiency is often the primary factor in calculating future energy demand and environmental pollution problems, where waste heat recovery plays an important role. The organic Rankine cycle (ORC) continues to attract widespread attention from researchers and/or manufacturers due to its technical compatibility, feasibility and reliability for low to moderate waste heat sources. This article presents optimization analysis on flue gas assisted organic Rankine cycles based on energy and exergy concepts. In this study, an optimization study was carried out with the Taguchi method using two turbine cycles to convert thermal energy into electrical and/or mechanical energy. The parameters for the optimization study were selected as turbine inlet pressure P1, cycle intermediate pressure P2 and fluid ratio PC3 transferred from the turbine to the heat exchanger at intermediate pressure. According to the results obtained, it has been determined that the most effective parameter on the first and second law efficiencies of the ORC cycle is the turbine inlet pressure (70.23% for the 1st law, 72.38% for the 2nd law).
