Title in Portuguese
Análise da aplicação da biomassa da cana como fonte de energia elétrica: usina de açúcar, etanol e bioeletricidade.
Keywords in Portuguese
Bioeletricidade
Biomassa da cana
Cogeração
Energia renovável
Indústria sucroalcooleira
Vapor
Abstract in Portuguese
Apresenta-se neste trabalho a aplicação de turbogeradores instalados em usinas de açúcar e etanol como alternativa eficiente de complementaridade do sistema energético brasileiro e contribuição à utilização de recursos renováveis, além de fazer abordagem aos sistemas de cogeração para este tipo de aplicação. A biomassa da cana-de-açúcar dispõe de um potencial energético significativo e o trabalho visa abordar os recursos para transformação da energia química contida neste combustível em energias térmica e elétrica, úteis para o processo industrial das usinas de açúcar e etanol. Também são explorados os métodos de dimensionamento das termelétricas a vapor que operam em conjunto com o processo fabril destas indústrias. Adicionalmente são avaliados métodos para favorecer a eficiência energética dos projetos de cogeração nas indústrias sucroalcooleiras a fim de elevar o potencial de geração de bioeletricidade e contribuir com a rentabilidade global da usina por meio da comercialização desta energia.

Sugar cane biomass
Abstract in English
This work presents the application of turbine generator sets installed in sugar and ethanol mills as an efficient alternative of complement of the Brazilian power system and contribution to the use of renewable resources, besides to cogeneration systems approach for this kind of application. The sugar cane biomass has a great energetic potential and the work aims to mention the transformation of the chemical energy contained in this fuel into thermal and electrical energy, useful for the sugar and ethanol industrial process. The design criteria of steam power plant operating together with the process of these industries are also explored. Additionally methods to improve the efficiency of the cogeneration projects in sugar and ethanol mills to increase the power generation potential are evaluated, contributing to the global profitability of the mill through the commercialization of this energy.
