Inyector de doble propulsion de combustible que comprende una primera canalizacion denominada alta presion, y una segunda canalizacion llamada baja presion, rodeando la segunda a la primera canalizacion, la que comprende en su extremo al menos dos orificios de emisión de combustible, divergendo los ejes de los orificios de al menos 16 ºc; un quemador; horno de vidrio; y procedimiento asociado.

摘要

The invention relates to a double pulse fuel injector comprising a first line (27) known as the high-pressure line and a second line (26) known as the low-pressure line, the second line surrounding the first, the first line at its end comprising at least two orifices (23, 24) for ejecting fuel, the axes of said two orifices diverging by at least 16°C. The invention is more particularly intended for glass making furnaces fitted with regenerators, notably transverse or loop burners, notably for melting glass so that it can be formed into flat glass in a float unit or for producing hollow glass ware. The device makes it possible to substantially reduce the temperature at the top of the regenerator. Alternatively, it is possible to elect to increase the power of the burner and therefore the productivity while at the same time keeping the same temperature at the regenerator that recovers the flow gases from the burner.
