Effect of variable air flow on the energy efficiency of a centralized combustion air system
The research analyzes how manual control in the combustion air system in furnaces of a metallurgical plant can generate energy overconsumption, by using the throttling of a damper with the use of manipulated valves to manually regulate the air flow.

En la investigación se analiza como el control manual en el sistema de aire de combustión en hornos de una planta metalúrgica puede generar sobreconsumo de energía, al utilizar la estrangulación de un dámper con el uso de válvulas manipuladas para regular de forma manual el flujo de aire, donde los ventiladores centrífugos del sistema trabajan todo el tiempo a plena capacidad y esto produce pérdidas de energía eléctrica, debido a la dinámica operativa del sistema. La demanda del sistema es variable y su programarla resulta difícil, por ello se evaluó una alternativa que consiste en controlar el accionamiento de los ventiladores a través de variadores de velocidad con un lazo de control proporcional integral que permite establecer el flujo de aire a través de la medición no directa del flujo de aire, utilizando la variable presión para lograr una reducción de la demanda de potencia del 30 % con el sistema de control. 2023-10-02 2023-11-17T20:52:53Z 2023-11-17T20:52:53Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://revistas.tec.ac.cr/index.php/tec_marcha/article/view/6295 10.18845/tm.v36i4.6295 https://hdl.handle.net/2238/14668 spa https://revistas.tec.ac.cr/index.php/tec_marcha/article/view/6295/6705 Derechos de autor 2023 Revista Tecnología en Marcha https://creativecommons.org/licenses/by-nc-nd/4.0 application/pdf Editorial Tecnológica de Costa Rica (entidad editora) Tecnología en marcha Journal; 2023: Vol. 36 Núm. 4: Octubre-Diciembre 2023; Pág. 19-30 Revista Tecnología en Marcha; 2023: Vol. 36 Núm. 4: Octubre-Diciembre 2023; Pág. 19-30 2215-3241 0379-3982 |
