Abstract:
ABSTRACT – The energy generation by the sugar-energy sector occurs simultaneously in the modalities: process heat, mechanical energy, electric energy for own consumption and excess, predominantly from sugarcane bagasse. It is intended the technological and economic aspects systemic approach, in order to contribute to the bioenergy definitive insertion, coming from the sugar-energy sector, as a great relevance complementary alternative, to support the Brazilian energy matrix. Considering that the 68 bar and 100 bar units yield were modeled at 38.97% and 42.80%, no doubt the steam generator system replacement could be an extreme importance procedure from the technical and economical view point, for increasing efficiency and, consequently, raising the revenues with the surplus electric energy generation, in the 25.63% to order 86,499 MWh / crop, equivalent to 15.57 million Reais, to a MWh traded at CCEE / ANEEL at R$ 180.00, corresponding to a R$ 15.57 million value to be added, for a 212.80 tons sugarcane bagasse processing.
