Abstract

Gaz türbini çevrimlerinde, son on yılda yapılan çalışmalarda önemli gelişmeler görülmektedir. Bununla birlikte çevrimin verimini attırabilmek için farklı uygulamalar üzerine çalışmalar yapılmaktadır. Bu çalışmada, ayrı ayrı CO2 (karbondioksit veya R744) ve hava akışkanlı süperkritik Brayton çevrimlerinin termodinamik analizi yapılmıştır. Süperkritik koşullarda çalışan çevrim ekipmanlarının farklı çevrim parametrelerinde enerji ekserji verimliliği ve net gücü alınarak, türbin giriş sıcaklık ve basıncının etkileri, kompresör basınç oranı ve kompresör verimlerinin performans üzerine etkileri incelenmiştir. Analiz çalışması bir bilgisayar yazılımı (Engineering Equation Solver-EES) ile çözümlenmiştir. Güç çevrimlerindeki verim artışına, süperkritik CO2 (S-CO2) türbinlerinin etkisi değerlendirilmiş ve enerji sektöründeki geleceği tartışılmıştır.

Abstract

Enormous strides have been made on gas turbine cycles in recent years. In addition, different practices of studies are being carried on in order to increase the cycle efficiency. In this study, CO2 (carbon dioxide or R744) and thermo dynamic analysis of supercritical Brayton cycles having air flow fluidity have separately been studied. Cyclical equipment working in supercritical conditions and its energy exergy performance at different cycles of parameters, and turbine inlet temperature and the effects of pressure, and compressor pressure ratio, and compressor efficiency on performance are surveyed examined. Analyze work is sorted out through a computer software (Engineering Equation Solver-EES).Supercritical CO2 (S-CO2) turbine effects on efficiency increase in power conversions are evaluated and its future in the energy sector is discussed.
