Description

The invention relates to the building materials industry, in particular, to devices for the production of glass &. Famous bath glass furnace with a device for cooling pool walls. The pool is cooled by means of a plate installed outside the pool that is tightly attached to the wall and irrigated with vrdoy 13. The disadvantage of this design is that the heat lost by the pool during cooling is not used. In addition, in the event of refractory corroding and uneven heat loads, the cooled metal wall is warped, and as a result of this, the thermal contact is disturbed, causing the pool cooling to become ineffective. Closest to the proposed technical essence and the achieved result is a bath, glass, boiled furnace, containing a basin with evaporative cooling. The pipes are welded into horizontally arranged collectors of the evaporative cooling system. An evaporating element, made of a set of vertical pipes, welded into the collectors, is mounted on a square that is attached in the usual way to the framework of the C2 furnace. A disadvantage of the known furnace is the low cooling efficiency of the refractory masonry of the pool due to the difficulty of ensuring good temperature contact between the refractory and the cooled pipes. This is because heat conducting coating is applied between the evaporative cooling elements and the pool refractory, which, during drying and oven brooding, usually splits for 7 seconds and settles down, resulting in areas cooled with the help of evaporative cooling elements that do not come in contact with the refractory masonry pool. - As a rule, with this method of protecting the refractory masonry of the pool, after broods and during operation of the furnace, as a result of the difference in thermal expansions of the pool bar and evaporative cooling elements, the air gaps between them and cooling of the refractory material are ineffective. The goal of the invention is to ensure the operation of the furnace, to increase the purity of the obtained product and to save the consumption of refractories.

The goal is achieved by the fact that the glass-melting furnace bath, including a pool with evaporative cooling, is equipped with metal combs arranged between the pipes and evaporation cooling, the pins of which are inserted into the pool masonry.

FIG. 1 shows a furnace, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 - evaporative element; in fig. 4 - the same, from the pool.

The glass furnace furnace bath contains a basin 1 with its evaporative cooling 2 placed in the side walls, consisting of a cooling tube 3 welded to the upper 4 and lower 5 horizontal collectors of the upper structure including side walls 6, arch 7, loading system 8 and 9 unloading and exhaust pipe to 10, The furnace is heated by means of burners 11.

Cooling pipes 3 are separated from each other by metal combs 12, mounted on the outside of pool 1 and provided with pins 13 projecting into the pool at a height sufficient (10-60 mm) to hold the refractory coating 14.

The furnace works as follows. The mixture is loaded into the glass-melting furnace furnace through the loading window 8, then it enters the B pool 1, where it is varied by means of torches of the burners 11. The welded glass mass is fed to the output through the discharge window 9. The products of combustion from the gas-gas space of the furnace formed by the side walls of the furnace and arch 7 are removed through the chimney stove to 10. When raw materials are melted, a skull is formed on the walls of pool 1 formed by cooled pipes 3. The erosion of the relatively thin (compared to the refractory masonry) refractory coating 14, which has good thermal contact and is fixed with the help of combs 12 with pins 13, is much slower than the refractory lining ki. With this design, the cooled pipes 3 in any case have a hot but thin layer of refractory coating that protects them from overheating.

Thus, the reliability of operation of the furnace is increased, continuous, long-term operation of the pool is ensured, the possibility of further intensification of the smelting process, saving of refractory material is ensured. ;

The economic effect from the use of the proposed furnace will be 125 thousand rubles. in gbd. The total economic effect from the use of the invention in five exploited and dual-built furnaces at V / O plants. The glass plastic will amount to approximately 800 thousand rubles. in year.
