Una revisión de los últimos avances de los colectores solares térmicos aplicados en la industria Willian Carrión-Chamba Wilson Murillo-Torres Andrés Montero-Izquierdo Ingeniería Energía solar aplicaciones industriales colectores solares térmicos El consumo energético asociado al sector de la industria representa el 38 % de la demanda de energía a nivel global, siendo un aspecto importante que marca el desarrollo de un país. En este sentido, es sumamente importante diversificar las distintas fuentes de energía e incorporar el uso de fuentes renovables de energía, como la solar, no solamente con la idea de asegurar el suministro energético, sino también considerando como elementos que permitan la reducción de las emisiones generadas por el uso de combustibles fósiles. El presente trabajo aborda las principales tecnologías de colectores solares que pueden ser incorporadas a distintos tipos de industrias, basado en experiencias e investigaciones en otros países. Sobre la base de esta revisión, se ha visto que una buena parte de las industrias a nivel mundial requieren temperaturas en sus procesos hasta los 250 °C, lo que hace idóneo el uso de esta tecnología. En función de cada industria, se podrán usar colectores solares de placa plana, de tubos de vacío, del tipo Fresnel o cilindro parabólicos. Por último, se detallan los ahorros asociados a algunas instalaciones y se abordan los desafíos relacionados con este sector. 2022 artículo científico 1390-650X https://www.redalyc.org/articulo.oa?id=505569631006 https://www.redalyc.org/journal/5055/505569631006/ https://www.redalyc.org/journal/5055/505569631006/html/ https://www.redalyc.org/journal/5055/505569631006/505569631006.epub https://www.redalyc.org/journal/5055/505569631006/movil https://doi.org/10.17163/ings.n27.2022.06 es http://www.redalyc.org/revista.oa?id=5055 Ingenius.
