Ülkemizde ve dünyada elektrik enerjisi tüketimi giderek artmaktadır. Elektrik enerjisi ve ısı enerjisi birincil enerjilerdir ve endüstride ve hayatımızda hayati bir role sahiptir. Bu iki enerjinin farklı döngülerde üretilmesi, enerji kaybına ve verimin düşmesine neden olur. Her ikisinin de aynı çevrimde üretilmesi ile verim çok artar, enerji kayıpları ve emisyon değerleri çok azalır. Elektrik ve ısı enerjisi üretmek için kojenerasyon sistemi kurularak, enerji tüketim maliyetleri önemli ölçüde azaltılabilir. Gaz türbini çıkışında egzoz gazlarından alınan ısı ile yanma odasına giren yakıtın ve havanın ısıtıldığı çevrim, ekserji analizi yöntemi ve termodinamiğin birinci ve ikinci yasaları kullanılarak analiz edilmiştir. Egzoz gazlarında kalan ısı enerjisi, bu çevrimde havayı ve yakıtı ısıtmak için bir miktar ısı enerjisi tüketildikten sonra buhar üretiminde kullanılır. Türbin, reküperatör kompresör, yanma odası, ısı eşanjörü gibi çevrimi oluşturan cihazların ve tüm çevrim için performans analizleri elde edilmiş ve tartışılmıştır. Cihazların ekserji verimi, ekserji kayıpları ve diğer performans parametreleri elde edilmiş ve tartışılmıştır.

The electrical energy consumption is increasing in our country and in the world. The electrical energy and heat energy are primary energies and has a vital role on industry and our lives. The production of these two energies in different cycles leads to energy loss and low efficiency. With the production of both in the same cycle, the efficiency increases a lot, and the energy losses and emission values decrease a lot. By installing cogeneration system to produce electrical and heat energy, the energy consumption costs can be reduced importantly. The cycle in which the fuel and the air entering into combustion chamber is heated by the heat taken from the exhaust gases at the outlet of the gas turbine is analyzed by using exergy analysis method and, first and second laws of thermodynamics. The heat energy remained in the exhaust gases are used to produce in steam production, after some heat energy is consumed to heat the air and the fuel, in this cycle. The performance analysis of the devices that make up the cycle such as turbine, recuperator compressor, combustion chamber, and heat exchanger and for the whole cycle and were obtained and discussed. Exergy efficiency, exergy losses and other performance parameters of the devices were obtained and discussed.
