Description

The invention relates to the glass industry and is intended for melting glass, except quartz.

The purpose of the invention is to increase the individual removal of glass mass, to improve the quality.

Figure 1 shows a glass melting furnace; figure 2 is the same, the view in the plan.

The continuous glass-melting furnace contains loading pockets 1, heat-reflecting screens 2, cooking basin 3, bubbling nozzles 4, overheating zones 5, homogenizing 6, brightening 7, duct 8, burner 9, diverting channel 10, arch 11.

The mixture through the loading pockets 1 enters the cooking basin 3, where, with forced mixing with compressed air entering through the bubbling nozzles 4, the processes of silicate and glass formation take place. From the heat-reflecting screens 2 at the beginning of the cooking pool, the charge heaps receive additional heat, which ensures a rapid process of silicate formation and intensifies, fits the cooking process as a whole. Next, the raspav arrives at the overheating zone 5, made so that the area of the cooking basin refers to the area of the overheating zone to ak (4-5): 5 (1-2). Such dimensions provide a certain saving of the refractory material and a sufficiently low viscosity of the glass melt, necessary for normal averaging. With a larger limit of the ratio of the area of the cooking basin, the required heating of the molten glass mass and, hence, its viscosity decrease, do not receive. With less

The limit of the ratio of the area of the cooking zone to the area of the overheating zone the consumption of refractory material will be unreasonably large, which leads to a rise in the cost of building the furnace.

The glass mass averaged in zone 6 of homogenization enters zone 7. clarification and then through the recessed channel 8 to the production. Evacuation of the exhaust gases is carried out through the flue exhaust channel 10 located in the roof 11, Moreover, before leaving the furnace, the exhaust gases release part of the heat with a heat-reflecting screen 2. The heat mode is maintained by means of burners 9,

The test results with a total oven area of 21 m, a cooking zone area of 7.0 m, and an overheated area of 1.98 m are shown in the table.

It can be seen from the table above that an increase in the removal of glass melt, an improvement in its quality and a reduction in construction costs can only be achieved by fulfilling the proposed ratio of cooking and overheating zones, namely when the area of the cooking basin relates to the area of the overheating zone as (4-5) :( 1-2)

Invention Formula

A continuous glass melting furnace, including cooking zones, overheating, homogenization, clarification, characterized in that, in order to increase the specific removal of glass, improve quality, the ratio of areas of cooking and overheating is (4-5) :( 1- 2)
