Desarrollo de un sistema automático implementado sobre un caldero pirotubular en el laboratorio de procesos industriales en la Facultad de Ciencias-ESPOCH.

Abstract

The present paper is about the development of the automatic system implemented on a fire tube boiler in the laboratory of industrial processes in Sciences Faculty at Escuela Superior Politécnica de Chimborazo. A maintenance of the mechanical parts of the boiler was carried out and the deteriorated pieces were replaced. Sensors and actuators with required specifications were selected for automatization. The boiler control system was implemented with a burner, a water pump, a pressure switch, a sensor PT100 located on the boiler; a PLC S7-1200, a touch panel KTP600, protection devices and a power supply were installed in the control panel. A sequency program in a PLC (Programmable Logic Controller) by software TIA Portal V13 was generated for the system daily extending the use of the system. It was concluded that the automated system let the students accelerate the interships with dynamic and learning speed. It is recommended that the students check the operation manual before using the equipment to avoid that users have accidents and the system is damaged.
