Description of the Related Art A feeder for a glass melting furnace is constructed as a part of the glass melting furnace to guide the glass melted in the glass melting furnace to a glass forming machine while controlling the temperature thereof. A number of combustion burners are attached to the wall to control the temperature.

る。By the way, depending on the type of glass, the color tone and the foaming state are greatly influenced by the atmosphere in the furnace. For such glass, it is necessary to strictly adjust the atmosphere in the feeder. Particularly when a method called a color feeder in which a coloring frit or pellets is charged in a feeder is adopted, a desired color may not be produced depending on the atmosphere in the feeder.

う問題があった。Therefore, conventionally, a method has been adopted in which the atmosphere in the feeder is made to be an oxidizing atmosphere or a reducing atmosphere by changing the mixed state of gas and air in a large number of combustion burners attached to both side walls of the feeder. Came. However, this method has a problem that the atmosphere adjustment width is narrow because the burner must be burned, and the atmosphere on the glass surface cannot be directly adjusted.

It was completed to provide a feeder.

It is characterized in that a large number of adjusting nozzles are provided.

FIG. 1 is a sectional view of a feeder of a glass melting furnace, in which 1 is a channel brick of the feeder, 2 is a side wall brick, and 3 is a ceiling brick. The side wall bricks 2 on both sides are preferably provided with a large number of combustion burners 4 obliquely downward. Further, in the feeder of the present invention, a large number of atmosphere adjusting nozzles 5 are provided below the combustion burners 4. These atmosphere adjusting nozzles 5 can directly control the atmosphere near the glass surface by ejecting an oxidizing-reducing atmosphere adjusting gas from the lower side of the combustion burner 4. The combustion burner 4 may be installed horizontally.

る。The feeder of the glass melting furnace of the present invention thus constructed is similar to the conventional one in that the temperature of the molten glass flowing inside can be controlled by the combustion burner 4, but below the combustion burner 4. By blowing out the atmosphere adjusting gas from the atmosphere adjusting nozzle 5 provided on the side, the atmosphere on the glass surface can be directly controlled. Moreover, this atmosphere control can be freely performed independently of the burner combustion, so that the adjustment range can be widened, and it is particularly suitable when a strict atmosphere adjustment is required as in a color feeder. .

ができる。FIG. 2 shows an example of an atmosphere adjusting method, in which the atmosphere in the feeder is measured by an atmosphere measuring device 6 such as an O 2 meter, and the atmosphere is adjusted to be ejected from the atmosphere adjusting nozzle 5 manually or automatically. The amount of atmosphere adjusting gas may be controlled. As the atmosphere adjusting gas, for example, air, nitrogen gas and the like are representative, but any gas can be used as long as the atmosphere can be adjusted.
