Burner Assembly for Glass Melting Furnace {BURNER ASSEMBLY FOR GLASS FURNACE}

The present invention relates to a burner assembly for a melting furnace, and more particularly, to maintain pressure in the melting furnace and to easily control temperature, and to effectively prevent waste gas generated in the melting furnace from being discharged to the outside through the nozzle entry hole. It relates to a burner assembly for glass melting furnace.

Generally, a glass melting furnace for supplying a liquid glass material to a molding apparatus for molding a glass product includes a melting furnace for heating a solid glass raw material to about 1500 ° C. or higher to make it liquid, and about 1100 to It is composed of a clarification part to keep the temperature at about 1200 ° C, and a feeder and a bowl to form a flow path of the glass to supply the glass material clarified from the clarification part to a molding apparatus. It usually consists of refractory bricks to prevent their release.

On the other hand, the left and right edges of the furnace are provided with a plurality of burner nozzles are inserted into the furnace to heat the solid glass raw material, when the solid glass raw material is supplied into the melting furnace, each of the burner nozzles arranged on the left and right sides of the furnace are It alternately ascends through the nozzle entrance and sprays the flame into the furnace.

While the burner nozzles arranged on the left and right sides of the furnace are alternately elevated and sprayed into the furnace at predetermined intervals, one side of the heat storage chamber arranged side by side with the furnace supplies combustion air to the furnace. On the other side, the process of releasing waste gas generated in the furnace is repeated.

As such, the glass raw material supplied into the melting furnace is changed into liquid glass by the combustion air of the heat storage chamber and the plurality of burner nozzles that inject the flame into the melting furnace.

However, in the conventional burner assembly for glass melting furnace, waste gas in the melting furnace is discharged to the outside through a gap between the nozzle access hole and the burner nozzle in the process of injecting a flame into the melting furnace by inserting a burner nozzle at the lower nozzle access hole of the melting furnace. In addition to the problem of polluting the working environment, the external air is introduced into the furnace through this gap, it is difficult to properly manage the pressure and temperature in the furnace.

Accordingly, an object of the present invention is to provide a burner assembly for glass melting furnace, which can easily maintain pressure and temperature management in a melting furnace and effectively prevent the waste gas generated in the melting furnace from being discharged to the outside through the nozzle access hole. will be.

Hereinafter, with reference to the accompanying drawings will be described in detail for the subject innovation.

1 is a schematic plan view of a typical glass melting furnace, FIG. 2 is a schematic configuration diagram of a glass melting furnace equipped with a burner assembly according to the present invention, and FIG. 3 is a schematic view of a state in which the burner nozzle of the nozzle access hole of FIG. 2 is inserted. It is a cross-sectional view. As shown in these figures, the glass melting furnace comprises a raw material supply unit 10 for supplying a solid glass raw material, a melting furnace 16 for heating and melting the glass raw material to about 1500 ° C. or higher, and bubbles in the molten glass water. The clarification part 24 to be removed, the connection part 22 interposed between the melting furnace 16 and the clarification part 24, and the glass part from the melting furnace 16 cools as it passes, and the clarification part 24 is clarified. It has the feeder 26 which heats, cools, and stirs a glass thing, and supplies it to the shaping | molding apparatus 28. As shown in FIG.

The raw material supply unit 10 has a raw material input unit 13 into which the solid glass raw material is introduced into the melting furnace 16, and a raw material supply motor 12 for controlling the input amount of the glass raw material into the raw material input unit 13, and the melting furnace Burner blocks 30 are provided in both side regions of 16, in which a plurality of burner assemblies 34 are installed to heat-melt the glass raw material supplied into the melting furnace 16. In the end region of each burner block 30, a heat storage chamber 18 in which combustion air is supplied into the melting furnace 16 and waste gas generated in the melting furnace 16 is discharged is arranged in parallel with the melting furnace 16. As shown in FIG. 2, the burner block 30 which connects the melting furnace 16 and the heat storage chamber 18 mutually is provided between 16 and the heat storage chamber 18. In addition, a plurality of nozzle entry holes 32 are formed at the lower end of the burner block 30 to allow the burner nozzle 35 to enter and exit, and at the opening edge of the nozzle entry hole 32, a cutoff provided in the burner nozzle 35. The guide protrusion 31 which guides the member 37 to block the opening of the nozzle entrance hole 32 is formed.

The burner assembly 34 provided in the lower region of the nozzle entrance hole 32 has a burner support member 36 which is installed at an angle to support the burner nozzle 35 and a cylinder (not shown) provided in the burner support member 36. It has a conveyance part 40 provided to be movable along the edge of the burner support member 36, and the fixing part 38 which couples the burner nozzle 35 to the edge part of the conveyance part 40. As shown in FIG.

On the other hand, the outer edge of the cylindrical burner nozzle 35 selectively blocks the gap between the nozzle access hole 32 and the burner nozzle 35 in conjunction with the burner nozzle 35 which is lifted into the nozzle access hole 32. A blocking member 37 is formed in a plate shape and is formed so as to surround the burner nozzle 35 in a ring shape.

By the above structure, when glass raw material is supplied from the raw material input part 13 into the melting furnace 16, the burner nozzle 35 of the burner block 30 formed in the both side area | region of the melting furnace 16 is ignited, and the melting furnace 16 The flame is sprayed into).
