Evaluación técnica para un sistema de calentamiento de agua a través de tubos evacuados en la producción de sal de grano en el Municipio de Petatlán, Gro

The present work focuses on the technical evaluation of a water heating system for the production of salt grain in the coastal region of the municipality of Petatlán, Guerrero, with the purpose of increasing efficiency in the production process of said same product that is obtained by evaporating the water, taking advantage of the abundant available solar resource. For which a solar collector system is designed that through vacuum glass tubes the fluid is circulated at a low speed, increasing its temperature and accelerating the production process. The system is built using low cost materials and with sustainable criteria which is used in exploratory and field research where statistical data on solar radiation, volumetric flow of available salt water, temperature of the environment, among others have been compiled for later be analyzed and together determine the efficiency of the grain salt production process that will benefit the productive sector of the Costa Grande de Guerrero.
