は困難であつた。(Prior art) Water-cooled oxygen burners have traditionally been used in glass melting furnaces such as frits, but hydrogen components generated from the glass raw materials condense on the surface of the burner body inserted into the furnace. This produced acid and gradually eroded the burner body, eventually leading to an accident in which water spouted into the furnace. Therefore, the present applicant succeeded in extending the life of the burner by changing the material of the burner body to a Ni-Mo-Cr alloy, etc., and has already proposed this in Japanese Patent Application No. 62-65993. When the fluorine gas concentration is high, it is still difficult to reliably prevent burner corrosion.

It was completed with the aim of creating a burner for glass thermal spacing that can prevent this from occurring.

のである。(Means for solving the problem) The present invention is to attach a protective tube made of a corrosion-resistant metal such as stainless steel to the outer periphery of the burner body, which is inserted into the inside of a glass blast furnace where fluorine gas is generated. The flange part of the burner body is detachably fixed to the flange part of the burner body so that it can be replaced, and purge air is supplied between the protection tube and the burner body, and the tip of the protection tube and the tip of the burner body are It is characterized by providing a slit in between which allows purge air to be jetted out at a constant flow rate.

This is the burner body that is inserted inside the burner. In this embodiment, the burner body 3
is 58% Ni, Mo17 known as Hastelloy C
%, W5%, Cr14% nickel-based alloy is used, but it is not necessarily limited to this.

The protective tube 4 has a wall thickness of, for example, about 3 mm, and has a flange portion 5 at its rear end removably fixed to a flange 6 of the burner body 3 with bolts 7.
The structure is such that purge air is supplied between the protection tube 4 and the burner body 3 from an air blowing hole 8 provided in the protection tube 4. Furthermore, a slit 9 is formed at the tip of the protective tube 4 for blowing out purge air at a constant flow rate. Note that 10 is a combustion gas supply port, and 11 is an oxygen supply port.

に比較してはるかに経済的である。(Function) Like conventional burners, the burner is inserted into the glass melting furnace 1 to melt glass, such as a frit that generates fluorine gas. Since the outer periphery is covered with the protective tube 4 made of a corrosion-resistant metal, the burner body 3 is not directly corroded by the acid component. Moreover, purge air is supplied between the burner body 3 and the protection tube 4, and this purge air is supplied to the tip of the protection tube 4 and the burner body 3.
The burner main body 3 is doubly protected by the protective tube 4 and the purge air layer because the burner main body acid is cooled while flowing out at an almost constant speed by the action of the slit 9 provided between the burner main body 3 and the tip of the burner main body 3. Therefore, there is no risk of corrosion even after long-term use. Although it is not possible to completely prevent the protective tube 4 from being corroded by the acid, in the present invention, the flange portion 5 at the rear end of the protective tube 4 is removably fixed to the flange portion of the burner body 3. Since it is said to be replaceable by doing so, it can be easily replaced each time the protective tube 4 is eroded to a certain degree, and it is much more economical than replacing the expensive burner body as in the past. .

Therefore, the present invention has extremely great practical value as a glass melting burner that solves the problems of the conventional burner.
