Abstract
FORNO DE FUNDIçãO DE VIDRO E PROCESSO PARA A FUNDIçãO DE VIDROS. A presente invenção refere-se a um forno de fundição de vidro com uma banheira (5) e um forno superior (1) com uma cobertura de forno (4) e um comprimento interno total ("Lg"), com uma região de pré-aquecimento (16) para material de carga (14) e com uma câmara de combustão (19) com queimadores (20). Para alcançar o objetivo de apresentar um forno de fundição de vidro e um processo operacional para este, por meio dos quais sejam respeitadas as normas legais para os limites de sobrecarga do meio ambiente, sem prejudicar a rentabilidade económica e sem que sejam necessários processos, instalações e equipes operacionais adicionais, de acordo com a invenção se propõe que: a) entre a região de pré-aquecimento (16) e a câmara de combustão (19) seja disposta uma única parede de radiação (15), através da qual o comprimento ("Lv") da região de pré-aquecimento (16) fica limitado a valores de 15 a 35% do comprimento total interno ("Lg") e o comprimento ("Lf") da câmara de combustão (19) fica expandido para valores de 65 a 85% do comprimento total interno ("Lg"); b) a região de pré-aquecimento (16) seja projetada para um pré-aquecimento do material de carga (14) exclusivamente interno ao forno c) uma fonte de gás para o gás de oxidação contenha uma porcentagem de oxigênio de no mínimo 85 por cento em volume de oxigênio, e que d) a pelo menos uma saida (18) da região de pré-aquecimento (16) para os gases de exaustão sem conexão intermediária de um permutador de calor seja conectada com a atmosfera.
