Abstract:
In this study, exergy is used to measure the performance of Delta IV power station located in Ughelli, Delta State, Nigeria. The choice of exergy as a means for performance appraisal is based on the fact that it provides a birds eye view of the sources of the major losses in the system, thus giving us a clue on how best to optimize the system under observation. Analyses are done using the first and second law of thermodynamics and results are presented in tables. In the exegetic analyses, mass and energy conservation laws were applied to each component. The compressor was seen to have the largest exergetic efficiency while that of the total plant was 45.7%. The combustion chamber had the largest exergetic destruction (56%) while that of the total plant was 58.5%
