Análise térmica de um trocador de calor do tipo casco e tubo em um processo de recuperação de energia

Abstract

This work focuses on the modeling of a shell-and-tube heat exchanger applied to thermal energy recovery in electricity generation systems powered by biogas. To provide context, the main milestones in energy generation are briefly presented, highlighting the growth of biogas as a renewable source in Brazil, driven by its environmental, economic, and energy-related benefits. The research concentrates on recovering heat from the exhaust gases of generator sets, aiming to improve the overall efficiency of the system. For this purpose, the Bell-Delaware method was used in the thermal and fluid dynamic modeling of the heat exchanger, with the goal of ensuring good performance while maintaining technical and economic feasibility. Finally, the study briefly compares the results obtained with real-world situations, emphasizing the importance of always considering practical data and concrete references when applying any calculation methodology.
