Computer Simulation of a Gas Turbine Performance

چکیده
The current research is aimed at carrying out an exergy analysis of a 33-MW gas turbine power plant that operates on the Brayton cycle. Quantitative exergy analysis for each component and for the whole system was done. Based on the exergy balance models developed, a computer program is written which is used to investigate the performance of the power plant under varying ambient and turbine inlet temperature conditions. The result obtained shows that the largest amount of exergy destruction occurs in the combustion chamber and the least in the gas turbine. The simulation reveals remarkable dependency of the exergy flow rate of the power output, exergy efficiency, exergy destruction, heat-to-power ratio and the specific fuel consumption on the change in the ambient temperature and turbine inlet temperature of the plant.
