Abstract

The present research aims to analyze, improve, optimize and implement an ignition system with hydraulic microgeneration of a gas boiler to avoid the use of batteries. The methodology based on the state of the art started from an extensive bibliographic search to the parametric configuration of redesign of a hydrogenerator. The input variables applied to the current model were measured experimentally to determine a complete redesign of the geometry. A complete CFD and structural analysis was performed using ANSYS software of the initial and final design of the micro hydrogenerator based on the new conditions. The geometry of the device was redesigned based on the results of the simulations. The 3D modeling was done in the Solid Works software. For the construction of the final redesign, CNC machining techniques were used, using the instruments of the CAD CAM laboratory at the Faculty of Mechanics and the Siemens NX software. Functionality was tested by measuring input and output variables, marking the behavior of the generating device, and simulating it in a transfer function in Matlab´s Simulink tool. A comparative cost analysis of the first model and the final redesign was carried out to determine the cost and benefit margin. New geometries were obtained related to the diameters and variation of the number of turbines blades, thickness increase and material change. The flow speed was three times higher and the pressure six times higher than the first model, a máximum voltage of 16.6V and 0.301A current was obtained. The cost-benefit factor was 1.1. Finally, an optimal redesign was obtained under the current conditions of use, demonstrating a considerable increase in power and an acceptable economic viability accomplishing the objectives.
