“…The first law of thermodynamics emphasizes that energy cannot be created out of nothing and existing energy cannot be destroyed. Since the total energy does not change, it has been important to determine what is consumed in energy systems [1]. As a common result of the first and second laws of thermodynamics, it was determined that the exergy is consumed in the energy systems.…”

In this study, first law (energy conservation) and second law (exergy) analyzes of thermodynamics were performed for a thermal power plant. It is very important to perform energy and exergy analyzes in industrial plants. These analyzes can provide guidance on improving energy efficiency and recycling waste energy. For these analyses, coals with different contents, available in nine different countries, were considered. According to the analysis, the highest first law efficiency was determined as 53.61% in the second type of coal. The second highest law efficiency was determined as 46.67% in the 6th coal type. Environmental Destruction Index and Sustainability Index values were determined and it was seen that, the highest EDI value was obtained in the 2nd coal type and the highest SI value was obtained in the 6th coal type. According to this study, the efficiency of the 6th coal type, which has the highest second law efficiency, was observed.

“…Management of change in real operation in actual plant (Wang et al, 2020), however, is a very investment demanding process, and it is therefore necessary to take into consideration that such a fundamental change is planned in range of years (S. Zhu et al, 2022), rather decades. On the other hand, it is possible to modify currently installed steam production technology (Khaleel et al, 2022) to make it more e cient (Katla et al, 2020, Mondal et al, 2020.…”

The demand for high-strength grade fibers and consumption of viscose fibers shows increasing tendency and growing trends in use of this product. Regenerated cellulose-based fibers of various properties are produced in order to meet all needs using new production technologies developed especially in recent years. One of the key processes in fiber spinning is continuous drying before final winding on spools. The manufacturing methods used for viscose fibers allows production of various types, parameters and specifications of fibers. It is therefore increasingly necessary to implement and standardize a drying concept to stabilize subprocess in a continuous production manufacturing as much as possible within the desired parameters of the final product. These activities and methods embody concepts for production of the highest quality fibers suitable to both producers and users. Currently, the concept of drying viscose fibers in a continuous production process is a problem that affects its final shape and quality properties such as commercial weight, linear density and tensile properties of all products and lengths for staple fibers as well as shrinkage and twisting for yarns of fibers. Due to that, development of technology enabling maximum stabilization of the drying process to achieve long-term sustainable final fiber quality parameters was adopted as a strategic project, including incorporation of efficient solutions for the overall energy intensity of this process in order to reduce the manufacturing carbon footprint by 23.81%. The production of viscose fibers and the project also aims to achieve significant energy savings up to 24 509.9 GJ·year-1.

“…Bu nedenle mevcut kurulu kömür yakıtlı termik santrallerin veriminin iyileştirilmesi; enerji üretiminin artması ve karbon salınım miktarlarının azaltılması gibi hem ekonomik hem de çevresel faktörler açısından önemlidir. Ekserji analizi kurulu santrallerin verimlerinin iyileştirilmesi için kullanılabilir iş kayıplarının ne oranda hangi bileşende gerçekleştiğinin belirlenmesinde önemli bir araçtır ve literatürde yaygın olarak kullanılmaktadır [6]. Arslan, Seyitömer Termik Santrali için yaptığı enerji ve ekserji analizinde en fazla ekserji kaybının kazanda olduğunu tespit etmiştir [7].…”

Fosil yakıtlı güç üretim sistemlerinin verimliliğinin artırılması; enerji üretiminin artması, yakıt kaynaklarının, çevre, ekosistem ve insan sağlığının korunması açısından önemlidir. Verim artırma uğraşları için enerji ve ekserji analizleri enerji sistemlerimdeki enerji kayıplarının ve kullanılabilir is potansiyelinin belirlenmesinde önemli araçlardır. Bu çalışmada 157 MW Kurulu gücündeki Kangal Termik Santrali 3. ünitesinin enerji ve ekserji analizi yapılmıştır. Hesaplamalar 34 farklı noktadan elde edilen veriler kullanılarak termik santral ünitesinin her bir elemanı için gerçekleştirilmiştir. En yüksek ekserji kayıp oranı kazanda elde edilirken (84,768%) en düşük ekserji kaybı kondenser tahliye pompasında elde edilmiştir (0,0089%). İkinci yasa verimi en fazla yüksek basınçlı besleme suyu ısıtıcısında (%97,73) ve en az kazanda (%52,43) gerçekleşmiştir. Termik santral ünitesinin ısıl ve ikinci yasa verimleri sırasıyla %32,92 ve %53,53 olarak bulunmuştur. Elde edilen sonuçların termik santralin optimize edilmesinde faydalı olacağı düşünülmektedir.
