Auditoría energética y exergética del sistema de vapor de la industria novacero “planta Quito”.

Abstract

In the present work, an energy and exergetic audit of the steam system of the NOVACERO S.A "Planta Quito" industry was carried out, in order to quantify the available, used and wasted energy of the steam system and establish solutions that optimize energy consumption. Based on the methodology of the ISO-50002 standard, all the necessary documentation of the steam system was compiled through a bibliographic review and information provided by the company. Through adequate instrumentation, the parameters were obtained to determine the performance of the boiler, based on information provided by the company, the steam consumption was determined and through thermography the energy losses in the steam and return conduction lines were located. of condensate, establishing a general performance of the steam system, an exergetic analysis of the boiler was carried out and based on the measurements and calculations made, performance indices were determined in order to indicate the current state of the system. In addition, possible solutions that optimize energy consumption were established, such as: optimal insulation, correction of excess air and implementation of a revaporized tank, which through a technical-economic analysis determined the feasibility of investment on savings opportunities. energetic. Based on the study carried out and the availability of the company, 2 of the 3 established improvement proposals were carried out, obtaining savings in the fuel consumption of the boiler. It is worth mentioning that fuel savings represent a decrease in CO2 emissions.
