Bir Reküperatörün Basınç Düşüşleri ve İşletme Maliyetleri Göz önünde bulundurularak Teknoekonomik Optimizasyonu

Bu çalışmada, hedeflenen sıcaklık aralığında çalışan bir gazdan gaza ısı değiştiricinin (reküperatör) ısı transferi ve maliyet optimizasyonu yapılmıştır. Öncelikle atık ısı kaynağının termofiziksel özellikleri ve akışların hacimsel debileri elde edilerek geri kazanılabilecek maksimum ısı elde edilmiştir. Daha sonra reküperatörü boyutlandırmak için parametrik bir çalışma yapılmıştır. Sıcak akış ve soğuk akış çıkış sıcaklıkları gibi maliyeti etkileyen parametreler, toplam ısı transfer katsayısı, etkinlik ve basınç düşüşü dikkate alınarak belirlendi. Son olarak, parametrik çalışmadan elde edilen termal parametreler teknoekonomik analizde kullanılmıştır. En yüksek tasarruf katsayısına sahip reküperatör geometrisi, yatırım ve işletme maliyetleri dikkate alınarak belirlenmiştir. Sonuç olarak, 108. Simülasyonda elde edilen geometrideki reküperatörün 321.19 m2 ısı transfer yüzey alanı ile yılda 653 252 $ ile maksimum tasarruf sağlayabileceği tespit edilmiştir.

Technoeconomic Optimization of a Recuperator Considering Pressure Drops And Operating Costs

In this study, heat transfer and cost optimization of a gas-to-gas heat exchanger (recuperator) operating in the targeted temperature range has been made. Firstly, the thermophysical properties of the waste heat source and the volumetric flow rates of the flows were obtained, and the maximum heat that could be recovered was obtained. Afterward, a parametric study was carried out to size the recuperator. The parameters affecting the cost, such as hot flow and cold flow outlet temperatures, were determined by the overall heat transfer coefficient, effectiveness, and pressure drop. Finally, the thermal parameters obtained from the parametric study are used in the technoeconomic analysis. The recuperator geometry with the maximum saving coefficient was determined considering investment and operating costs. As a result, the 108th simulation resulted in maximum savings with 653 252 $/year using 321.19 m2 heat transfer surface area.
