Diseño del control de combustión para una caldera pirotubular, utilizando el controlador hibrido hc900 honeywell, visualizado por medio del software plantscape vista r400.

Abstract

The present study is based in the combustion controls in boilers, has been developed an automation design, for a part of the process, as the system of combustion controls, used for the steam production in the field industrial. In the Ecuadorian industrial park the most industries there are not automated this process, many use a mechanical system for control and regulate the air damper modulation and fuel, the main object is free the air and fuel actuator and reduce the fuel consumption of the combustion. For the implementation of the control combustion, is used industrial instrumentation with signal 4-20 mA as pressure transmitters, flow transmitters, oxygen analyzer, temperature transmitter, and electrical actuators. In the automation is used the Hybrid Controller HC900 Honeywell, this have the ports rs485 and Ethernet, in the first is connect a flame safety control, this send the information about the ignition of the burner of the boiler. By Ethernet port is connect the computer for the supervisory of the process by the software of the supervisions and acquisitions of information Vista Plantscape R400.
