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.
