Abstract
Un método de producción y afinado de vidrio incluye monitorear la temperatura de un baño de vidrio fundido (24) contenido dentro de una cámara de afinado (72) de un recipiente de afinado (14) y, en base a la temperatura monitoreada, controlar la cantidad de un agente de afinado químico de sulfato añadido en una masa fundida de vidrio (18) contenida dentro de una cámara de reacción interior (30) de un fundidor de combustión sumergida aguas arriba (12) que alimenta el recipiente de afinado (14). La temperatura del baño de vidrio fundido (24) se puede determinar dentro de una zona de indicación de temperatura (118) que abarca una porción subsuperficial (120) del baño de vidrio fundido (24) que se encuentra adyacente a un piso (76) de una carcasa (70) del recipiente de afinado (14). Al monitorear la temperatura del baño de vidrio fundido (24) y controlando la cantidad de agente de afinado químico de sulfato añadido al vidrio fundido (18) del fundidor de combustión sumergida (12), se puede minimizar el desperdicio del agente de afinado químico de sulfato y hacer más eficiente el proceso de afinado.
