Abstract

Se describe un método para producir vidrio usando fundición por combustión sumergida. El método incluye la introducción de un material de alimentación vitrificable (30) en una masa de vidrio fundido (22) contenido dentro de un fundidor de combustión sumergido (10). La masa de vidrio fundido contenida en el fundidor tiene una relación redox definida como una relación de Fe2+ al hierro total en la masa de vidrio fundido. El método incluye además quemar una mezcla de gases combustibles (G) suministrada a cada uno de los quemadores sumergidos (62) para producir productos de combustión (68) y descargar los productos de combustión directamente en la masa de vidrio fundido. Aún más, el método incluye ajustar la relación redox de la masa de vidrio fundido controlando una o más condiciones operativas del fundidor de combustión sumergida seleccionado de (1) una relación de oxígeno a combustible de la mezcla de gas combustible suministrada a cada uno de los quemadores sumergidos, (2) un tiempo de residencia de la masa de vidrio fundido y (3) un flujo de gas a través de la masa de vidrio fundido.
