Sistema de control de temperatura para el quemador PellasX, mediante la regulación del suministro de pellets de madera y aire.

Abstract

This curricular integration research project aimed to design a temperature control system that operates between 0°C to 300°C for the PellasX burner by modulating the supply of wood pellets and air. For this, bibliographical references on pellet burners, their operation, structure, and their control systems were investigated, and the requirements the system must meet were defined. The mechanical, electrical, electronic, and control design of the Pellas X Mini burner was carried out, which allowed for meeting the requirements demanded by the burner control; in addition, a human-machine interface (HMI) was used to make it easy to operate, to be able to supervise, control and monitor the system in real-time, which allowed configuring on times, ash cleaning times, off times, burner work cycle times, together with burner temperature control. Different parameters of the constitutive stages of the project and compliance with the proposed requirements were evaluated. The validation of the temperature sensor was established through tests of accuracy and repeatability of the measurements, and validation of the equipment through on/off tests and cleaning through the tests proposed for its correct operation.
