Способ по п.1, в котором нагнетаемый свежий кислород находится в газовом потоке, содержащем от 20,9 до 100% кислорода. ! 3. Способ по п.1, в котором инжектор включает по меньшей мере один нагнетательный канал, размещенный в своде печи. ! 4. Способ по п.3, в котором по меньшей мере один нагнетательный канал включает трубчатый элемент, имеющий первый конец, соединенный с источником свежего кислорода, и второй конец, оканчивающийся в печной атмосфере, для подачи свежего кислорода в указанную область для горения с присутствующими газами и присутствующим кислородом. ! 5. Способ по п.1, в котором свежий кислород подают вблизи загрузочного кармана печи по соседству по меньшей мере с одной горелкой. ! 6. Способ по п.1, в котором свежий кислород подают в указанную область по направлению, совпадающему с продольной центральной линией печи. ! 7. Способ по п.1, далее включающий введени� 1. A method for intensifying combustion in a glass-melting furnace having at least one burner, a charging pocket, an outlet, side walls and a roof forming a combustion chamber for the furnace, the method comprising:! determining the area of the combustion chamber where the atmosphere in the furnace requires an increase in the oxygen content for combustion in the furnace atmosphere; ! injecting fresh oxygen through an injector in the roof of the furnace into the specified area with a controlled flow rate for combustion; ! creating a suction effect for the furnace atmosphere in the combustion chamber, depending on the supplied fresh oxygen, in which the furnace atmosphere is circulated to mix the gases present and the oxygen present in the furnace with fresh oxygen supplied to the specified area for combustion. ! 2. The method of claim 1, wherein the injected fresh oxygen is in a gas stream containing 20.9% to 100% oxygen. ! 3.
