Utilization of Waste Materials from Industrial Processes of a Brazilian Sugarcane Mill for Energy Production

Abstract:

This work presents the thermodynamic, thermoeconomic, and economic analyses of utilization of waste materials from industrial processes of a modern Brazilian sugarcane mill (bagasse, straw and vinasse) for energy production. The first case considers a conventional steam thermal power plant constituted, among other equipment, by a steam boiler of high-pressure and high-temperature and by an extraction-condensation steam turbine, being all mechanical driving electrified, and using just bagasse as fuel. The second case considers a modified steam thermal power plant in which is incorporated systems to be possible the utilization of straw and vinasse as complementary fuel to bagasse by means of a combined cycle, with the addition of a gas turbine and a heat recovery steam generator, among other equipment.
