Abstract:The aim of this study is to analyse performances of thermal systems in a combined power plant, which is producing electricity and heat simultaneously, by using finite time thermodynamics method. In the study, combined gas-steam cycle used in combined heat and power systems is investigated. Thermodynamic performances of an irreversible closed Brayton cycle at maximum power density and maximum power output of an endoreversible Rankine cycles are analyzed in the viewpoint of finite time thermodynamics or entropy generation minimization method. The obtained results of maximum power output criterion are compared with those results obtained at maximum power density in the analysis of Brayton cycle. The results are compared with the data from real gas turbines. On the other hand, results obtained from maximum power output and observed data from actual power plants are compared in the analysis of Rankine cycle. Consequently, design parameters affecting the thermodynamic performances of cycles are investigated separately and it has seen that results obtained from the analyses are in good agreement with data from actual power plants and real gas turbines.
