Abstract

Изобретение относится к ванной стекловаренной печи с подковообразным пламенем с низкими выбросами NOx, оснащенной потолочной горелкой, включающей впускной канал для окислителя, содержащего от 15 до 30% кислорода в ее стенке выше по потоку, канал для отведения дымовых отходящих газов в ее стенке выше по потоку и систему вдувания со скоростью звука, включающую по меньшей мере один инжектор для вдувания струи газа со скоростью, по меньшей мере равной 80% скорости звука, называемый соно-скоростным инжектором, отверстие в стенке выше по потоку или отверстие в канале для отведения дымовых отходящих газов, причем указанный соно-скоростной инжектор вдувает свой газ в режиме противотока относительно потока дымовых отходящих газов, которые направляются в сторону канала для отведения дымовых отходящих газов. Изобретение также относится к способу получения расплавленного стекла, включающему плавление стекла в указанной печи.
