Análisis térmico para evaluar eficiencia en un calderín Pirotubular de 2 BHP del laboratorio de la Carrera de Ingeniería Mecánica

Abstract

Was evaluated efficiency by applying techniques of thermography in a 2BHP boiler of the career of mechanical engineering of the Technical University of Ambato. The data were taken using technological equipment: thermal camera, thermocouple, thermometer digital, bimetal thermometer, combustion gas analyzer and volumetric meter of GLP. Was obtained thermograms, temperature of gases, temperature of steam pipes, composition of gases, volumetric composition of products and consumption of GLP.Analysis was performed using the indirect method, was calculated losses caused by heat transfer (convection and radiation) 17.4%, combustion 5.17%, unburnt 8.7% and not quantified losses 10%. Was determined an efficiency of 59%. Finally, was proposed four proposals to improve the functioning of the boiler and was executed maintenance cleaning of tubes and burner due to time a financial resource, obtaining a fuel-saving of 0.12 kg/h and the reduction in the temperature of the combustion gases.
