Automatización de un horno industrial a gas con PLC y su monitoreo a distancia

Abstract

The main objective of this project is to automate the operational efficiency and safety of industrial environments by means of a programmable logic controller (PLC) for the realization of control engineering practices. This system is based on the integration of process sensors, such as thermocouples and pressure gauges that allow the PLC to perform sophisticated algorithms for the precise control of critical parameters such as temperature and pressure, providing an optimal performance of the furnace. For the implementation of this prototype, we have a manual main valve which will give way to the total gas flow, followed by a manual ball valve for protection of the proportional control system, which allows to maintain control of the natural gas. Next, the pressure sensor measures the natural gas flow from the proportional system to the burner located at the bottom of the oven. The burner also has an electric ignition spark which will contact the gas and then the flame will be produced. In the upper part of the oven, the temperature sensor is positioned at an angle to obtain a better reading of the temperature data. Finally, several tests were performed for the correct operation of the equipment as well as a scada method for local monitoring and for remote monitoring it was done through Node Red.
