Exergy Analysis of a Power Plant in Abu Dhabi (UAE)

This study presents four analysis at unit 4 Kamojang geothermal power plant are exergy analysis at current condition, exergy efficiency optimization, economic optimization, and exergoeconomic optimization with wellhead valve pressure as a variable. Calculations are conducted by using the MATLAB. Thermodynamics characteristic of geothermal fluid assumed as water characteristic which get from REFPROP. Wellhead pressure operational condition 10 bar has exergy efficiency 31.91%. Exergy efficiency optimization has wellhead valve pressure 5.06 bar, exergy efficiency 47.3%, and system cost US$ 3,957,100. Economic optimization has well pressure 11 bar, exergy efficiency 22.13%, and system cost US$ 2,242,200. Exergoeconomic optimization has 15 optimum condition. Exergoeconomic optimization aims to analyze the optimum wellhead valve pressure for maximum exergy efficiency and minimum cost of power plant system.

This paper took one 330MW unit boiler in one power plant as an example, then doing some research about the boiler system energy change through doing exergy analysis. After this, the exergy flow equation was established, the energy transfer, utilize and loss of the thermal power plant production was revealed, the exergy efficiency of the boiler was defined. So the paper can provide a basis for energy utilization of power plant.
