Análise termodinâmica de uma termelétrica operando com ciclo combinado brayton-rankine

Abstract

The generation of thermoelectric energy is necessary for today and for the future, as even with many issues against it, such as pollution and scarcity of the main fuels used, thermoelectric generation corresponds to a large part of the total energy used in the world and guarantees energy security. In Brazil, thermoelectric generation have an important role in the country's energy matrix, especially when rainfall is scarce. The technological development in this sector aimed at increasing efficiency as well as, using renewable or less polluting fuels and reducing costs is of paramount interest. Thus, this work comes to develop a more efficient combined cycle, from a different arrangement the devices used and, using a computer simulation tool to optimize the energy and exergy efficiencies of the proposed cycle.
