The invention relates to a glass melting furnace including a channel-shaped melting end. According to the invention, the raw materials are introduced at an upstream end and the molten glass is recovered at the downstream end, said furnace being heated by burners. At least 65% of the combustion energy is produced by oxycombustion and the burners are distributed on the walls along the length of the furnace. The majority of the flue gases are released close to the upstream end near the raw material inlets, the remainder being released close to the downstream part such as to maintain a dynamic seal in relation to the surrounding atmosphere. La presente invención se relaciona con un horno para fundir vidrio que comprende un tanque de fusión en forma de canal, los materiales de materia prima se introducen en un extremo corriente arriba, el vidrio fundido se recupera en el extremo corriente abajo, dicho horno se calienta por medio de quemadores, en los que se produce la energía de combustión por la combustión oxifuel con respecto a por lo menos el 65% de los mismos, los quemadores se distribuyen en las paredes a lo largo de la longitud del horno, en el que la descarga del gas de combustión se localiza principalmente cerca del extremo corriente arriba cerca de las aberturas a través de las cuales se introducen los materiales de materia prima, el resto del gas de combustión se elimina cerca de la parte corriente abajo con el fin de mantener el sellado dinámico con respecto a la atmósfera circundante.
