Thermoeconomic analysis of gas turbine based cycles

The thermoeconomic analysis of gas turbine based cycles is presented and di scussed in this paper The thermoeconomic analysis has been performed using the ThermoEconomic Modular Program (TEMP V.5.0) developed by Agazzani and M assardo (1997). The modular structure of the code allows the thermoeconomic analysis for different scenarios (turbine inlet temperature, pressure rati o, fuel cost, installation costs, operating hours per year, etc.) of a larg e number of advanced gas turbine cycles to be obtained in a fast and reliab le way. The simple cycle configuration results have been used to assess the cost functions and coefficient values. The results obtained for advanced g as turbine based cycles (inter-cooled, re-heated, regenerated and their com binations) are presented using new and useful representations: cost versus efficiency, cost versus specific work, and cost versus pressure ratio. The results, including productive diagram configurations, are discussed in deta il and compared to one another.
