S1  Análise de Sistemas Energéticos    Titulo: COGENERATION IN COMBINED CYCLES: A COMPUTATIONAL PROGRAM FOR EXERGOECONOMIC ANALYSIS   Resumo : 0ABSTRACT. THIS WORK PRESENTS THE DEVELOPMENT OF A COMPUTATIONAL PROGRAM FOR EXERGOECONOMIC ANALYSIS OF COGENERATION SYSTEMS THAT USE GAS TURBINES ASSOCIATED WITH THE RECOVERY BOILER AND STEAM TURBINE. THE COMPUTATIONAL PROGRAM SELECTS SYSTEMS OF GAS TURBINES, SEEKING THE OPERATION IN THERMAL PARITY, THROUGH A DATABASE COMPOSED OF GAS TURBINES COMMERCIALLY AVAILABLE IN THE MARKET. THE COMPUTATIONAL PROGRAM CORRECTS THE PARAMETERS OF PERFORMANCE OF THE SYSTEMS SELECTED FOR THE LOCAL CONDITIONS OF THE INSTALLATION. THE EXERGOECONOMIC ANALYSIS IS MADE BY TAKING INTO ACCOUNT MANUFACTURING OF EXERGETIC MANUFACTURE IN WHICH THE BEST SYSTEM IS CONSIDERED AMONG THEM SELECTED, IN ORDER TO PRESENT THE SMALLEST IRREVERSIBILTY INDEX. AN APPLICATION OF THE COMPUTATIONAL PROGRAM IS PRESENTED IN THIS WORK.
