Repotenciación de un caldero pirotubular horizontal en la Planta de Lacteos Tunshi de la ESPOCH.

Abstract

This graduation work called “REPOWERING HORIZONTAL PYRO-TUBULAR CAULDRON”, was intended to improve the performance and operation of the current equipment to facilitate and accelerate the production of different dairy products that are produced in the industrial plant Espoch-Tunshi. For which a survey and recording of the mechanical status, both internal and external and electrical equipment was made. The necessary information of the different parts of a horizontal Pirotubolar cauldron was collected and analyzed, such as diesel burners, water pump, buoy type water level sensors, pressure sensors, pressure cabin, flame duct, relief valves of pressure, etc. Afterwards, the respective maintenance was carried out, where the performance of the mentioned parts was optimized. The system is currently being controlled by a LOGO 8 SIEMENS Probable Logic Controller (PLC), which is responsible for receiving and processing the sensor data and controlling the actuators through the use of contactors, all within a Closed Loop control System. To get a better interaction between user-equipment, the system has a man machine interface (HMI) TOUCH of 4 ", both PLC and HMI were programmed in TIA PORTAL V13 and communicate through UTP CAT 6A ethernet. With the system implemented and checking the recorded data, an improvement of up to 60.75% was obtained in terms of waiting time for steam production of the equipment, which benefits the plant process, it should be noted that the team has an automatic ignition by the programmable clock. Yearly maintenance is recommended to the equipment in order to avoid accumulation of soot in the internal pipe.
