Abstract

PROCEDIMIENTO E INSTALACION PARA EL CALENTAMIENTO DE UN CANAL EN EL CUAL FLUYE UNA CORRIENTE DE VIDRIO EN FUSION, EN DIRECCION A UNA O A VARIAS MAQUINAS DE CONFORMACION. CARACTERIZADO PORQUE SE CALIENTAN LAS ZONAS MARGINALES LONGITUDINALES DE LA SUPERFICIE SUPERIOR DE LA CORRIENTE DE VIDRIO POR MEDIO DE CORTINAS DE LLAMAS PROCEDENTES DE QUEMADORES OXICOMBUSTIBLES, LAS CUALES SON DIRIGIDAS HACIA DICHAS ZONAS MARGINALES; Y PORQUE EL QUEMADOR OXICOMBUSTIBLE ESTA COLOCADO A UNA DISTANCIA TAL DE LA SUPERFICIE DEL BAÑO DE VIDRIO EN FUSION, QUE EL PUNTO DE IMPACTO DE CADA LLAMA SOBRE DICHO BAÑO SE EFECTUA CUANDO TODOS LOS GASES DE LA LLAMA ESTAN QUEMADOS. DE APLICACION EN LINEAS DE FABRICACION CONTINUA DEL VIDRIO.
