[0005] The object of the present invention is to provide a glass kiln and method using high-temperature flue gas to help melt glass, so as to overcome the disadvantage of high cost of the glass melting system. While the temperature is stable, the cost of melting can be reduced, and the high-temperature flue gas obtained by combustion can be used to heat the molten glass for melting, thereby reducing the use of electric boosting and the electric power of the electric boosting system, thereby reducing the cost of the melting process

Abstract
The invention discloses a glass kiln and method for fluxing glass by using high-temperature flue gas. In the process in which flue gas generated after combustion of fuel and oxygen is discharged through a flue gas outlet, part of the flue gas flows into a flue gas pipeline from the top end of the flue gas pipeline, and exchanges heat with molten glass when passing through a liquid pool area to provide heat for the molten glass so as to achieve the purpose of fluxing. Use of an electric fluxing device is reduced to a certain extent, the electric power of the electric fluxing system is reduced, and the cost of the melting process is reduced.
Description
technical field [0001] The invention relates to the field of glass product manufacturing, in particular to a glass kiln and method using high-temperature flue gas to help melt glass. Background technique [0002] The glass industry has always been a high energy-consuming and high-pollution industry. The glass furnace is the key equipment in the glass production process. According to different functions, it can be divided into several parts such as the feeding area, the melting part and the cooling area. The melting part of the glass furnace is divided into two parts according to the upper and lower parts: the flame space and the liquid pool area. The flame space is composed of the front wall, the breast wall, the large wall at the top and the glass liquid surface at the bottom. Among them, the breast wall is provided with a number of spray gun (burner) inlets. During the glass melting process, the fuel and oxygen react to produce flames. The flame gases use heat to melt the...
