Resumen

ALBAN, Carlos Alfredo Pérez; GARCIA, Alexis Cordovés  y  BENALCAZAR, Jorge Román Terán. Design and implementation of a control system to improve the quality of the combustion gases in the fire-tube boiler of 5 BHP. Enfoque UTE [online]. 2016, vol.7, n.2, pp.55-68. ISSN 1390-6542.  https://doi.org/10.29019/enfoqueute.v7n2.95.

The goal of this paper is the design and implementation of a system for controlling the quality of the combustion gases in a fire-tube boiler of 5 BHP. Based on the percentage of O2 present in the combustion gases, measured by a lambda sensor, the percentage of CO2 emitted into the atmosphere is determined. PID proportional control is responsible for the automatic regulation of the entry of air to the boiler by an actuator, according to the percentage of the oxygen concentration in the combustion gases. The control system has an HMI display and a modular PLC. The results achieved ensure pollutant gases emissions within the parameters established by current environmental standards, achieving the required quality of combustion gases and reducing the fuel consumption of the boiler.

Palabras clave : steam boiler; lambda sensor; HMI display; programmable logic control..
