Thermoeconomic analysis of marine gas turbines

Thermoeconomic analysis approach is expounded in this paper.According to thermodynamic model of marine gas turbines,the thermoeconomic model is built.Estimate methods of purchased equipment cost of gas turbines are discussed.The result shows that the total cost rate of marine gas turbines has a minimum,The price of fuel and the number of operating hours per year of gas turbines have important influence on total cost rate of equipment.
