Description

In conventional glass furnaces, all the steps of the glass process: vare and sshka, cooking, luminescence and studs occur in an IB common pool. The latter, in certain types of bath furnaces, can be constructively divided into separate parts, where the connection between these stages is maintained. The high quality of the glass melt and the performance of the existing furnaces are the result of proper coupling of the work and dimension of individual parts of the bathtub of the furnace, where the process of obtaining glass melt from flowing to generation is consistently carried out, and the bath capacity is a function of the area, mainly of the heated part. ovens.

To achieve this goal, glass melting furnaces are well-known, equipped with prechambers and channels from the bath to pre-melt the furnace.

In the proposed furnace for melting glass and similar materials, in order to increase the productivity of the furnace, the prechamber is equipped with an independent source of heating, and for carrying out various stages

glass formation under different conditions, under it is made of several inclined sections with different angle of inclination. For the possibility of changing the prechamber without disrupting the operation of the furnace, the prechamber is mounted on a trolley.

In the schematic drawing of FIG. 1 shows a longitudinal vertical section of a bath for glass melting and the like, FIG. 2- horizontal section of it.

The furnace is a combination of a glass-melting pool 5 with a pre-chamber (one or several), permanently located in the upper building 6 of the furnace or capable of being movable with installation on a trolley // for hauling it away from the pool during repair or when podkatka new for without disrupting the continuity of the furnace.

The chamber was made in the form of a shaft 2, connected to channel 4 with a basin 5 and provided with a hearth 5 made of several inclined sections with different tilt angle for the purpose of carrying out various stages of glass formation under different conditions. The prechamber is equipped with an independent source of heating in the form of a nozzle Yu installed in the combustion chamber 7. The gases from chamber 7 are discharged through gas ducts 8 to the chimney 9.

The charge loaded through the hopper is advanced from the top down through the chamber and heated by a separate heat source in the chamber itself. Simultaneous heating occurs due to the radiation of heat from the furnace bath to the bottom and bottom of the pre-chamber.

The mixture can enter the prechamber in the form of a briquetted charge with a battle, in the form of a mixture of briquettes in the usual charge and more in the form of a mixture of the usual charge with a fight.

The primary stages enter the passage стадии, inside the prechamber chamber: glassmaking — heating, dehydration, sintering of the charge and incomplete dissociation processes of carbonic and sulphate and other compounds of the charge, intercalation of oxides and the formation of multicomponent silicate compounds.

The outlet is w, and from the oblique hearth and the unclarified glass melt entering the pool 5 is subjected to the subsequent stage of glassmaking already in the pool. Thus, the heated part of the basin becomes already the predominantly refining part (clarification of the glass melt). Next, the glass melt is directed through the stud to the development.

This order of preBrash, the charge of the charge into the finished glass mass, makes it possible to free the bath from the primary glassmaking processes that require a large pool.

The furnace is freed from a large number of inclusions of refractory supplies in the glass, because the primary glass-fiber processes particularly strongly destroy the masonry in the area of the gravel and boiling.

In addition, in the proposed embodiment of the furnace, a number of significant factors are eliminated, the influence of yush, which negatively affects the operation of the furnace and

quality of glass melt, for example, volatilization of charge, clogging of regenerative nozzles, etc.

The proposed stove, due to the presence of a heated hearth and prechamber, makes it possible to increase the removal of glass melt from a square meter of heated part of the pool mirror and at the same time provide an increase in the coefficient of efficiency of the furnace with high quality glass melt.

The specified combination of heated hearth, pre-chamber and bath can be implemented on any glass-melting bath furnace, regardless of the shape, system and power of it.

The described combination contributes to the lengthening of the service life of bath furnaces even with the use of fully aggregate mechages and allows the introduction of various kinds of alkali substitutes (nepheline, syenite, etc.) and thus facilitate the introduction of low-grade raw materials.

It is possible to combine the described device with bath furnaces of other purposes, for example, chemical, metallurgical, etc.

The subject matter of the invention.
