Diseño de un quemador de gas tipo venturi con una potencia de 20 KW para los Laboratorios de la Carrera de Ingeniería Mecánica

Abstract

The methodology proposed for the design was software simulation using the finite element method with Solid 185 type elements; in addition to techniques such as observation and recording, for the design of the burner and annotation of the results of the calculations; The project is also of a bibliographic type since the theoretical support for the calculations is sought and it is descriptive because the efficiency of the burner is detailed step by step. The design and simulation parameters were: power, pressures, speeds, diameters and temperatures in order to verify the calculated results together with those obtained by software. Another objective was to obtain thermal losses by convection and radiation through calculations and fundamental heat transfer equations that resulted in 0.073 kW; Peripheral losses of 0.13.6 kW, frontal losses of 0.002 kW were also analyzed; unburned losses of 0.7 kW; and other types of losses with a value of 8,795 kW; After calculating the losses, it was determined that the useful energy of the burner corresponds to 10,294 kW, which results in a thermal efficiency of 51.47 percent. The burner accessories were selected from the catalog and the supports and the Venturi were designed considering a material that performs with the thermal performance. The data obtained from the simulation corroborates the calculated parameters and provides a graphic idea of how the burner will operate under the proposed conditions.
