Abstract
Un caso de estudio de un sistema de recuperación de calor es realizado en un horno industrial que consume gas natural, para determinar la capacidad de refrigeración que puede ser generado para aire acondicionado utilizando un equipo de refrigeración por absorción (LiBr-Agua). Se utiliza los gases de combustión que salen de la chimenea como fuente primaria de energía. Un análisis termodinámico y económico de todos los equipos del sistema (recuperador de calor, "chiller" de absorción, torre de enfriamiento, etc.) es realizado. Se presenta una metodología para evaluar el potencial de recuperación de calor del horno industrial, así como también las limitaciones que deben ser consideradas. La metodología también considera el impacto ambiental favorable que se tiene del proyecto de recuperación de calor. Los resultados demuestran que bajo ciertas características de operación, el sistema de recuperación de calor es técnica y económicamente factible de realizar.
A case study of a Heat Recovery System is performed in an industrial furnace that uses natural gas to determine the absorption cooling capacity (LiBr - Water) that can be generated for air conditioning. The energy source will be the heat of the flue gas that is eliminated by the furnace stack. Thermodynamic and economic analysis of the entire system (heat recovery exchanger, absorption chiller, cooling tower, etc.) is performed. A methodology to evaluate the Heat Recovery potential of the industrial furnace will be shown, as well as the limitations that must be considered. This methodology also considers the favorable environmental impact that is available to perform a heat recovery project. The results show that under certain operational characteristics and conditions, the heat recovery system is technically and economically feasible (profitable).
