The entropy generation principle of thermodynamics and statistical methodology have been used in the present work for evaluation of performance parameters of gas turbine–steam turbine (GT-ST)-based combined power generation system and assessment of major losses in components. The mathematical model is carried out for the quantitative analysis of exergy estimation, efficiency of parts in accurate manner. The statistical analysis is also agreed to examine the variations in performance of plant at different operating conditions. This research paper mainly deals with maximum exergy losses which are found in combustion chamber of GT system and exhaust flow system of ST system. The combined and exergetic efficiency of plant is found to be 41% and 38.5%, respectively. The statistical modeling concluded that the comparative results of performance parameters at different compression ratio of combustible gases affect the overall performance of combined GT-ST plant. This study helps to justify possible efficiency improvement with identifying the irreversibilities of plant utilities. |
