Abstract
In Brazil, sugarcane has a fundamental role in energy generation. Sugarcane bagasse is used in thermal plants to produce energy, However, sugarcane bagasse exhibit high moisture content, low density, low heating value. To improve the sugarcane bagasse, the torrefaction process could be an alternative to improve the physical and chemical properties. The literature presents diverse studies about sugarcane residues torrefaction, however, few studies on the combustion of this torrified biomass. In this study, the combustion of torrified sugarcane bagasse was simulated using Aspen Plus software. The results show that the HHV value can be predicted using ASPEN software. The combustion of torrefied sugarcane bagasse shows an exhaust gas rich in CO2 and water content was reduced. Torrefied sugarcane biomass at 200°C have a lower air fuel ratio, this condition shows a significant reduction in mass flow of exhaust gases.
