Análisis de pérdidas energéticas para mejora de eficiencia en el sistema cabina de pintura automotriz de la empresa Ciauto-Ambato

Abstract

The present experimental work is developed due to the efficiency improvement needs required by the air house system of the paint booth of the CIAUTO company. For this study, it began with an analysis that focuses on the recognition of the operation of the air injection system; Subsequently, the machines or mechanical, electrical and thermal equipment that make up the air house system were determined, this in order to identify possible failures. Infrared thermography was used for the maintenance analysis of the system, in this way thermographic analysis sheets were made for the evaluation of the equipment and machines in accordance with the guidelines that govern the ASNT - TC - 1A Standard (Qualification and Certification Guidelines for nondestructive essays). To improve equipment costs and efficiency, the recommendations of the FENERCOM Guide for Energy Saving in Industrial Installations were used. Two alternatives for energy use were evaluated, the first one tries to optimize the combustion process of the burners, preheating the air to 60 degrees centigrade resulting in an increase in thermal efficiency from 87,4 to 88,5 percent obtaining an increase in power up to 10 kW. The second alternative reuses the exhaust gases from the chimney, where 37,05 kW could be reused for the drying process.
