Caracterización de los parámetros de combustión del equipo TVCC instalado en el Laboratorio de Termodinámica de la Facultad de Ingeniería Mecánica de la Escuela Politécnica Nacional

Abstract

The aim of this work is to characterize the combustion parameters of the Edibon TVCC combustion chamber installed in the Thermodynamics Laboratory of Escuela Politécnica Nacional, using flame image processing. For this purpose, experimental data was obtained under different operating conditions, using LPG and diesel as fuels. The operating conditions were modified regulating the air admission to the burner with an inlet damper. For each operating condition, experimental data was obtained using the following equipment: a gas analyzer, an opacimeter and a digital camera. Combustion parameters such as: air-excess, efficiency, composition of the combustion gases were obtained with the gas analyzer. The opacimeter was used to determine the opacity of the exhaust gases in the chimney; and the camera was used to capture images of the flame, which were then processed and analyzed using Python programming. With the obtained data, characteristic curves were developed to describe the equipment behavior as a function of the percentage of air-excess in the combustion process. In addition, a statistical model was used to develop an equation that enables the prediction of the percentage of air-excess in a LPG combustion process using flame image processing.
