    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.

    Análisis del caldero de 125 BHP de potencia del Hospital Regional Docente de Ambato para determinar su rendimiento energético
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2018) Guamangallo Tandalla, Cristian Wladimir; Escobar Luna, Luis Eduardo
    For the realization of this project the use of measuring equipment was of great help as is the thermal camera, this equipment shows a thermal image of the sections or elements inspected, with this temperature the heat generated by the inspected sections was calculated, In addition, a smoke meter was used, this instrument is useful to determine the chemical composition that occurs at the moment of combustion and by means of stoichiometric calculations the air-fuel ratio was determined, which indicates the use that the fuel is generating within This equipment, with these data obtained from the tests, proceeded with the necessary calculations, for which thermodynamic criteria and heat transfer criteria were taken into account, with these data the determination was made of the performance that the boiler generates up to now. It is necessary to determine the performance of these equipment, because this factor helps to predict the change of some element that integrates this equipment, and thus extend its useful life. Concluded with the development of this project, the maintenance personnel were informed of the care they must have for a better management of this equipment, and the maintenance manager was also informed of the tests they must perform to determine the performance of this equipment, and If necessary, perform more frequent preventive maintenance.
