Abstract

En un método de operación un horno (100) de fundición de vidrio que comprende una zona (11) de fundición y una zona (12) de refinado, la zona de fundición está provista con pares de regeneradores opuestos (41, 42). Se inyectan por lo menos una corriente gaseosa o corriente de fluido atomizado de combustible y por lo menos una corriente de oxidante, por ejemplo, a través de los inyectores (32, 33) y se queman en la zona de refinado arriba del material fundido para fabricación de vidrio para incrementar la concentración promedio de oxígeno en la atmósfera cerca de dicha superficie del baño en dicha zona de refinado de 1 a 60% en volumen. Los regímenes de flujo de combustible y de aire para la combustión de cada uno de dichos orificios de regenerador se ajustan para hacer que la concentración de oxígeno en el gas de escape que sale de cada uno de dichos orificios de regenerador ubicados entre la zona de manantial en la zona (11) de fundición y la zona (12) de refinado tengan entre 2 y 10% en volumen. El vidrio oxidado puede hacerse y se disminuye el riesgo de corrosión de corona.
