Abstract
Description
[Technical Field]
[0001] The present invention relates to a glass melting furnace apparatus and a method for operating the same. [Background technology]
[0002] Cylindrical glass melting furnaces, which melt glass at high temperatures, are divided into an upper chamber and a lower chamber. The upper chamber generally has a sealed structure to prevent high-temperature gases from escaping to the outside. It is also equipped with an inlet for waste material, an exhaust gas outlet for exhausting combustion gases, and an oxygen supply pipe for supplying oxygen for combustion. Cylindrical glass melting furnaces operated in nuclear power systems require the ability to monitor the glass melting status and any abnormal phenomena during operation. However, because conventional glass melting furnaces have a single monitoring function, improvements to the monitoring and protection functions are required for stable facility operation. Summary of the Invention [Problem to be solved by the invention]
[0003] The problem that the present invention seeks to solve is to allow operators to continuously monitor the glass melt using a primary camera to monitor the state of the glass melt in real time.
[0004] In addition, if an abnormality occurs in the main monitoring means, a second monitoring means is used to perform dual equipment monitoring, thereby preventing unnecessary equipment shutdowns to inspect the monitoring means when an abnormality occurs.
[0005] In addition, in the event of an abnormally high temperature, the equipment can be stopped stably and protected if an abnormality occurs in the equipment through monitoring using thermography.
[0006] The objects of the present invention are not limited to those described above, and other objects not described will be clearly understood by those skilled in the art from the following description. [Means for solving the problem]

[0009] The main monitoring module and the first auxiliary monitoring module monitor regions on diagonally opposite sides of the melting object.
[0010] The first area monitored by the primary monitoring module and the second area monitored by the first auxiliary monitoring module at least partially overlap each other.
[0011] The upper chamber unit further includes a second auxiliary monitoring module mounted in the upper chamber, which measures and monitors the temperature of the glass melting object so that operation related to the glass melting is stopped if the main monitoring module and the first auxiliary monitoring module fail to function.
[0012] The glass melting furnace apparatus further includes a drive unit for vertically moving a second auxiliary monitoring module in the upper chamber unit, and the second auxiliary monitoring module is moved vertically by the drive unit according to the filling level of the glass melt in the lower chamber unit to correct the temperature measurement state for the glass melt.
[0013] The second auxiliary monitoring module is positioned vertically in the upper chamber, monitors less than 50% of the surface area of the glass melt, and is positioned between the main monitoring module and the first auxiliary monitoring module.
[0014] The glass melting furnace apparatus further includes a slab unit disposed below the lower chamber unit, and the slab unit includes a slab module and a heating module that surrounds the periphery of the lower chamber unit in the slab module and heats the object to be melted.

[0016] In order to achieve the above object, one aspect of the present invention provides a glass melting furnace apparatus, comprising an upper chamber unit and a lower chamber unit into which an object to be melted is introduced, the upper chamber unit comprehensively monitoring the introduction state of the object to be melted and the operating state of the glass melt in the lower chamber unit, the upper chamber unit comprising an upper chamber, a main monitoring module mounted in the upper chamber for monitoring the object to be melted in the operating state for the glass melt in the lower chamber unit, and a first auxiliary monitoring module mounted in the upper chamber for monitoring the object to be melted in the operating state for the glass melt in the lower chamber unit, the first auxiliary monitoring module operating in either a first mode in which it operates in combination with the main monitoring module, or a second mode in which it operates in place of the main monitoring module if the main monitoring module loses function. [Effects of the Invention]
[0017] According to the present invention as described above, one or more of the following advantages can be obtained.
[0018] The present invention allows operators to continuously monitor the state of the glass melt using a primary camera to monitor it in real time.

These embodiments are provided merely to complete the disclosure of the present invention and to fully convey the scope of the invention to those skilled in the art to which the present invention pertains. The present invention is defined solely by the scope of the claims. The same reference symbols refer to the same elements throughout the specification.
[0024] Referring to FIG. 1, a glass melting furnace apparatus (hereinafter referred to as “apparatus 100 ”) according to one embodiment of the present invention includes an upper chamber unit 110 , a drive unit 120 , a lower chamber unit 130 , a slab unit 140 and a control unit 150 .
[0025] 1 and 2, the upper chamber unit 110 includes a main monitoring module 112, a first auxiliary monitoring module 113, and a second auxiliary monitoring module 114. Referring to FIGS. 1 to 3, the lower chamber unit 130 includes a molten metal temperature measurement module 131.
[0026] 1 and 4, the slab unit 140 includes a slab module 141 and a heating module 142. Referring to Fig. 5, the upper chamber unit 110 of the apparatus 100 is equipped according to a set standard.
[0027] The object to be melted is introduced into the lower chamber unit 130 of the apparatus 100. The upper chamber unit 110 comprehensively monitors the introduction state of the object to be melted and the operating state of the lower chamber unit 130 related to the glass melt M.
[0028] Here, the main monitoring module 112 of the upper chamber 111 is mounted in the upper chamber 111. The main monitoring module 112 of the upper chamber 111 monitors the operation status of the lower chamber unit 130 for the glass melt M to be melted.
[0029] The first auxiliary monitoring module 113 of the upper chamber 111 is mounted in the upper chamber 111. The first auxiliary monitoring module 113 monitors the melting object during operation of the lower chamber unit 130 for the glass melt M.
[0030] The first auxiliary monitoring module 113 of the upper chamber 111 operates in at least one of a first mode and a second mode. The first auxiliary monitoring module 113 operates in combination with the main monitoring module 112 in the first mode.

Thereafter, the upper chamber unit 110 of the glass melting furnace apparatus 100 performs a comprehensive monitoring of the introduction state of the object to be melted and the operating state of the glass melt M in the lower chamber unit 130 (S120).
[0043] The main monitoring module 112 of the glass melting furnace apparatus 100 is mounted in the upper chamber 111 and monitors the state of the melting object in the operating state for the glass melt M in the lower chamber unit 130 .
[0044] In addition, the first auxiliary monitoring module 113 of the melting furnace apparatus 100 is mounted in the upper chamber 111 and monitors the state of the melting object during the operation of the lower chamber unit 130 for the glass melt M.
