Abstract

This paper describes the use of exergy analysis in evaluating the performance of Omotosho Phase I Gas Thermal Power Plant. The data used were obtained from data record book. The exergy analysis, mass and energy conservation laws were applied to each component. Results obtained show that the gas turbine had the largest exergy efficiency of 96.17%, while that of the total plant was 41.83%, the combustion chamber had the largest exergy destruction of 54.15% while that of the total plant was 58.17%.In addition, the effect of the gas turbine load variation and ambient temperature from 210C – 330C are investigated. The exergy efficiency decreases and exergy destruction efficiency increases as ambient temperature increases in the plant and its components. Therefore, turbine air inlet cooling system is recommended for the plant to solve this problem.
