Özet:

 Nowadays, one of the most important issues that countries pay attention to is energy, and energy consumption is increasing rapidly with constantly developing technologies. In order to meet these energy demands, the use of different fossil resource-based power technologies has become widespread. Additional problems such as the depletion of fossil resources and damage to the environment have led to increased in research on the more efficient operation of such technologies. Electricity generation by the Kalina cycle KC in medium- and low-temperature heat sources is one of the important technologies. The equipment of the Kalina cycle is a turbine, separator, pump, evaporator, condenser, mixing chamber, throttling valve, and heat exchangers. In this study, a model was created in order to make detailed thermodynamic analyses of the cycle in question, and the properties of all points in the system were calculated analytically using the Engineering Equation Solver EES program. The system performance is analyzed in terms of energy and economy depending on the turbine inlet pressure, condenser outlet temperature, and isentropic efficiency of the pump and turbine.

 Günümüzde, ülkelerin en önemli dikkat ettiği konulardan bir tanesi enerjidir ve sürekli gelişen teknolojilerle enerji tüketimi de hızla artış göstermektedir. Bu taleplerin karşılanması için fosil kaynak esaslı farklı güç teknolojilerinin kullanımı yaygınlaşmıştır. Fosil kaynakların, tükenecek olması, çevreye zarar vermesi gibi farklı problemler, bu tür teknolojilerin daha verimli çalıştırılmasına yönelik araştırmaların artmasına neden olmuştur. Orta ve düşük sıcaklıklı ısı kaynaklarında Kalina çevrimiyle KC elektrik üretimi önemli teknolojilerdendir. Kalina çevrimini oluşturan ekipmanlar, türbin, seperatör, pompa, buharlaştırıcı, kondenser, karışım odası, kısma valfi ve ısı değiştiricileridir. Bu çalışmada, ele alınan çevrimin detaylı termodinamik analizlerini yapabilmek için bir model oluşturulmuş ve Mühendislik Denklem Çözücüsü EES programı kullanılarak sistemde bulunan tüm noktaların özellikleri analitik olarak hesaplanmıştır. Sistemin türbin giriş basıncı, kondenser çıkış sıcaklığı, pompa ve türbinin izentropik verimlerine bağlı olarak sistem performansı enerji ve ekonomik açıdan analiz edilmiştir.
