Abstract

Un método para producir vidrio incluye descargar una salida (22, 1022) de vidrio fundido clarificado de un tanque de clarificación (18, 1018) de un aparato de clarificación de inducción al vacío (10, 1010) y suministrar el vidrio fundido clarificado en tanque de acondicionamiento térmico (16, 1016) que se separa del tanque de clarificación mediante un espacio abierto (26, 1026) ocupado por un entorno ambiental (24, 1024). El tanque de clarificación incluye un alojamiento verticalmente alargado (80, 1080) que define una cámara de clarificación interior (82, 1082) donde se recolecta y se mantiene un baño (76, 1076) de vidrio fundido. La cámara de clarificación interior se mantiene a presión subatmosférica y el alojamiento se rodea mediante al menos una bobina de inducción (74, 1074) para introducir calor en el baño de vidrio fundido. El vacío mantenido en la cámara de clarificación interior y la calefacción suministrada por la(s) bobina(s) de inducción promueven la ascensión de las burbujas de gas hacia arriba a través del baño de vidrio fundido. También se describe un sistema de producción de gas que incluye el aparato de clarificación de inducción al vacío.
