Abstract

Aims: The performance of gas turbine is influenced by a number of factors which may be classified under three main headings: design limiting conditions, environmental dependent conditions and system respond condition. The design limiting conditions have been found to have influenced gas turbine performance most. In this study, two design limiting conditions (pressure ratio and maximum cycle temperature) were evaluated and estimated for optimal design and operations of gas turbine. Study Design: Hierarchical order in selecting the two design condition parameters was proposed. Methodology: Steady state energy and exergy concept was used to model the behavior of the plant. Results: Result obtained indicated that at maximum cycle temperature of 1173K, 1273K, 1373K, 1473K, 1573K, and 1673K,maximum pressure ratio for optimal performance were 19, 24, 29, 36, 44 and 51 respectively. Conclusion: These results provide insight into the performance behavior of gas turbine and also serve as a guide for operations and design optimization.
