Abstract
Mejoras introducidas en el objeto de la patente principal número 423.806 por procedimiento de ventilación de un canal de distribución de vidrio fundido, cuyo canal de distribución comprende una solera y una bóveda que presentan dos partes en salientes, dirigidas hacia la superficie del vidrio para delimitar en la bóveda tres compartimentos longitudinales, el compartimento central que sirve de canal de ventilación y los compartimentos laterales que forman bóvedas de reverberación para el calor producido por unas resistencias de calentamiento colocadas lateralmente, alrededor de las orillas del canal y/o que sirven de conductos de evacuación para gases de combustión producidos por dos hileras de quemadores, colocados lateralmente y destinados a calentar las orillas del canal, según lo descrito en la patente principal.
