This study aims to analyze the main factors that affect the efficiency of a steam generation system, with emphasis on the influence of fuel moisture, the air/fuel ratio, and the role of auxiliary equipment. The methodology adopted combined a literature review of technical and scientific references with practical observation of boiler operation in an industrial environment. The methodology combined a bibliographic review of technical and scientific references with practical observation of the boiler’s operation in an industrial energy efficiency, since part of the heat released during combustion is used to evaporate the water contained in the fuel. To overcome this limitation, it is necessary to operate with excess air, ensuring more complete combustion and reducing pollutant emissions. It was also observed that auxiliary devices, such as the deaerator, economizer, and feedwater pumps, are essential to optimize performance and ensure operational safety. The study concludes that the efficiency of the system depends not only on the fuel quality but also on proper stoichiometric control and the implementation of automation technologies, which allow real-time adjustments of operating conditions. Therefore, the research highlights the importance of biomass-fired water-tube boilers as a feasible and sustainable alternative for the sugar-energy sector.ptcaldeiraaquatubularcana-de-açúcarbagaço.Trabalho de Conclusão de CursoENGENHARIAS
