    Diseño y construcción de un prototipo para recuperación de calor residual en el calderín pirotubular de 2 BHP del Laboratorio de Energía de la Carrera de Ingeniería Mecánica

    This technical project has the function of recovering the residual heat from the gases or fumes that are expelled directly into the environment by the boiler chimney, which will also contribute to a large extent to solve a deficit of equipment in the energy laboratory, and will help so that students can carry out practices of the theory learned. The compilation of information was carried out through reliable research sources such as magazines, books, scientific publications, and duly verified websites that provide relevant data to the project. First, the metallic heat recovery unit was chosen, then the design and simulation in software was carried out to verify its operation and thus can be validated and used, later it was passed to the manufacturing process, and finally it was completed with physical tests of operation. The simulation was carried out with the existing data of the temperature with which the combustion gases exit through the boiler chimney and with the support of the properties of the fluids found in the software library, also the data of the cold fluid that will be air at room temperature, when performing the simulation, the temperature increase of the cold fluid was verified by means of the circulation carried out during the heat recovery process. Finally, the results were obtained and it was observed that the lower the speed, the greater the increase in temperature we have of the cold fluid, to mention when the temperature is 20 degrees Celsius at a speed of 5 meters per second, it reaches a temperature of 34.2 degrees Celsius, all we can see the data with different speeds in the simulation results.
