Analizar la selección de materiales para un horno de cogeneración mediante métodos multicriterio

Abstract

The purpose of this research work is to choose an alternative material of easy availability at national level for a heat exchanger that is part of a cogeneration furnace. It is important to establish the selection of suitable and correct materials for the elaboration of a cogeneration equipment using multi-criteria methods, which will allow to identify the adequate raw material to obtain a 100% optimal product. For the present analysis, definitions and terms of cogeneration are taken into account since they are important for the understanding of this study, in addition, the biomass process used in the cogeneration system is taken into account. Within the design and simulation process of a heat exchanger that is part of a cogeneration furnace, being able to identify the correct material allows us to optimize the functionality, efficiency and applicability of the same, facilitating the obtaining of true data and favorable parameters to obtain a reliable product. In addition, it allows the application of processes within environmental, technological and environmental areas. The multi-criteria methods (MCDM) used are: Entropy, AHP which are used for criteria weighting; VIKOR, TOPSIS, COPRA, DOMINIC and Spearman Correlation were also used. According to the analysis carried out, it is established that the best alternative is AISI 440A Stainless Steel, due to its high resistance to corrosion and low cost; this was achieved through a comparative analysis of CFD simulation where it is established that the gas obtained in the cogeneration furnace is used inside a heat exchanger.
