Description

FIELD OF THE INVENTION The invention relates to the glass industry, to furnaces designed for melting crystal glass and high-grade glass.

The purpose of the invention is to improve the quality of glass, save fuel, increase the specific removal rate.

FIG. 1 shows a furnace, a longitudinal section; in fig. 2 - furnace plan.

The cooking basin 1 of the furnace is divided by a recessed additional screen 2 in the ratio (11-14) :( 2-4). Accepting a ratio greater than (11–14) :( 2–4) will result in a deterioration of the homogeneous glass mass behind the screen.

If the ratio is less than (11-14) :( 2-4), then burnout and recovery of oxide will occur - Sein 1 through the boot pocket 11.

fishing behind the barrier screen as a result of self-organized convection. The duct 3 under the additional screen 2 is designed in such a way that its height refers to the height of the screen as (1-1.5) :( 5-7), and the height of the duct 3 under the screen should be equal to the height of the duct 4 between the cooking 1 and the working 5 pools.

If the ratio is greater than (1-1.5): (5-7), a very high flow is obtained and the glass mass will not cool to the required temperature.

If a ratio less than (1-1.5) :( 5-7) is accepted, then the glass melt will not be well homogenized by enriching the glass melt with heavy components from the bottom layers. The same height of the ducts is decanted by the fact that at their different height there will be a discrepancy between the amount of glass mass entering the production basin 5 and the part of the cooking basin formed by the additional screen 2 and screen 6. If the duct under the additional screen 2 is larger, then the glass mass level is higher than the furnace circumference, as a result of which it will overflow through the additional screen 2. If the duct 3 under the barrier screen is less than the duct 4, the glass melt level between the additional screen will decrease th and the screen 6. Then maybe povsh1enie level in the pool to overflow the screen and undercooked glass through it.

The distance from the duct connecting the cooking and production pool

5, to the bottom of pool 7, refers to the height of the additional screen 2, as (1.5-2.5) :( 3-4). If the ratio is less than (1.5-2.5) :( 3-4),

This will result in the selection of glass melt from the upper layers between the additional screen 2 and the duct 4, which causes a reduced content of lead oxides and in the final

in the end, this will lead to a deterioration in the quality of the finished glassware.

The evacuation of gases is carried out by the flue gas exhaust 8; evacuation of gases from the production pool is dried; it is evacuated through the chimney stand to 9, the combustion mode is carried out by means of burners 10 located along the perimeter of the furnace and in the roof.

The mixture is loaded into the cooking bass5

0

In the first half of the cooking basin, up to the additional screen 2, all basic silicate reactions take place, the process of dissolution of the quartz grains completely takes place and is not averaged; the pool.

The duct 3 cools the glass melt to a predetermined temperature, averages it, and homogenizes the glass melt.

35 In the second part of the cooking basin 1, due to convective heat exchange, the glass mass is additionally averaged and the duct 4 enters the working pool 5. The additional screen 2 does not allow the upper layers of the glass mass, which partially burned out of oxides, to be produced. The evacuation of waste gases from the cooking basin 1 is carried out through the flue gas from the working pool through the flue gas stand to 9. The heat regime is maintained by means of the steam arches 10 and burners located

50 around the perimeter of the furnace.

Claims (1)

Invention Formula A glass melting furnace, comprising 55 cooking and working pools, separated by a screen and connected by a duct, and an additional screen installed in the cooking basin, characterized in that the goal of improving the quality of the glass melt, fuel economy, increasing the specific removal rate, the ratio of the areas of parts of the cooking basin before and after the additional screen is (11-14):: (2-4), the ratio of the height of the duct under the additional screen to its height is equal to (1-1.5) :( 5-7), and the ratio of the distance from the channel connecting the cooking and working pools to the bottom of the pool to the height of the additional screen is (1.5-2.5) :( 3- 4), and both ducts are made equal to the height.
