Abstract

Patente de Invenção: <B>"APARELHO E MéTODO PARA CONTROLAR O FLUXO DE VIDRO FUNDIDO ATRAVéS DE SEçãO DE FORNO DE FUNDIR VIDRO"<D>. Aparelho para controlar a taxa de fluxo de vidro fundido através de uma seção de forno (16) que inclui uma calha (28) está disposta na seção de forno para restringir a largura da seção de forno para o fluxo de vidro, tal que existe uma diferença em nível de vidro fundido na seção de forno a montante e a jusante da calha. Os sensores (44, 46) medem o nível de vidro fundido a montante e a jusante da calha, e um controlador (54) é responsivo aos sensores para determinar a taxa de vidro fundido através da seção de forno como uma função da diferença em nível de vidro fundido entre os sensores. A taxa de fluxo de vidro através da seção de forno é controlada como uma função da diferença em nível de vidro através da calha quando comparado com uma taxa de fluxo desejada estabelecida por um operador.
