The invention relates to glass production, in particular to glass melting furnaces for cooking various glasses,

The aim of the invention is to improve the quality of the glass and accelerate the cooking process.

Figure 1 shows a glass furnace, a longitudinal section; figure 2 - the same plan.

The glass melting furnace consists of a cooking basin 1, heated by burners 2, a loading pocket 3, smoke outlets 4, a working part 5 connected to the cooking pool 1 by duct 6, filled vertically, at the base with an L-shaped branch from the internal cooker Basin 1. The section of the channel 6 is the same throughout its length and is selected depending on the volume of the cooking pool for 1 and the specific removal of glass mass. In the end partition wall 7, windows 8 are left to connect the gas space of the cooking basin 1 with the working part 5. The cooking part 5 is made with a recess 9 and is connected to feeder feeders 10.

The furnace works as follows.

Through the boot pocket 3 into the weld pool 1, where silicate and glass formation reactions take place, the charge and the battle enter. The glass melt then goes to the zone of clarification and homogenization. Temperature difference of glass melt at the base of the L-shaped duct outlet 6 from the bass

by convection currents it moves into the recess 9 of the working part and, not having time to cool down, having mixed with the newly arrived glass melt, it is updated and comes to the production. As a result, only high quality glass melt from the working part 5 with good temperature uniformity enters the production. The temperature of the working part 5 is maintained due to the heat of the gas space of the cooking basin 1 through the openings 8 in the end wall 7. Removal of waste gases from the gas space of the cooking basin 1 is carried out through the exhaust ducts 4.

As a result of the introduction of the inventive furnaces of the present invention, the quality of the glass mass produced is significantly improved by eliminating the production of glass mass containing defects. In addition, the glass melt in the process of cooking and generation acquires the necessary homogeneity and temperature uniformity for production, and thus the process of cooking is accelerated and productivity increases.

If the height of the vertical part of the duct is less than 0.8 depth of the cooking basin, then the depth of the working part and the volume of glass mass in it will increase, which will require additional heating to ensure the temperature of generation. As a result of the reheating of the glass mass in the working part,

Seina 1 and working part 5, and

The presence of a vertical part of the duct 6 prevents the possibility of entraining the glass mass from the bottom, near-wall layers in the cooking basin 1 into the working part 5. At the same time, the possibility of the return movement of the glass melt that does not participate in the mining process is completely excluded , with the ability to cool and pollute the newly supplied glass mass in the duct 6 and before the duct in the cooking basin 1. The glass melt of the working part 5, mainly by idernyh feeders 10 is involved in the production.

Unnecessary glass melt, not involved in the development process,

midges on its surface. In addition, with an increase in the volume of the developed part, not all glass mass will be involved in the production process, which will lead to low-intensity glass exchange in this part.

If the height of the vertical part

duct will be over 0.85 depth

in the arched pool then respectively

the depth of the working part will decrease. Although the recess in the working part from the side of the duct remains, the difference between the base levels of the working part will decrease.

and feeder pit. At the same time, it is possible to hit the glass-glass production from the deepening of the working part, which did not have time to acquire full temperature uniformity (as a result

poor mixing by convection currents of newly arrived and cooled glass mass, which did not participate in the process of generation).

If the working part is made with a recess which is more than 0.15 of the depth of the cooking basin, the depth and, consequently, the volume of the working part increase, which will lead to the indicated drawbacks.

If the depression in the high-flow section is less than 0.1 times the depth of the cooking basin, then a decrease in the volume of the glass mass in the high-flow section and, accordingly, the depression may lead to the same drawbacks.
