[0012] Although there are many ways to reduce or eliminate foam in the glass kiln, there is no way to monitor the position of the foam layer, especially to adjust the two fuels with different carbon content according to the accurate monitoring of the position of the bubble boundary. It is an effective method to control the foam position by using the material ratio

Embodiment Construction
[0042] Unless otherwise defined, all terms used herein have meanings commonly understood by those of ordinary skill in the art to which the present invention belongs. When using the definitions of some of the following terms, terms used in the singular may also include the plural, and vice versa. The definitions of some terms given herein are only for describing specific embodiments and are not intended to be limiting.
[0043] In order to describe this article, the following definitions are made here:
[0044] In the glass furnace, glass raw materials are fed continuously from the raw material inlet at the upstream end, and burners are installed on both sides of the glass furnace. The burners are generally air burners or oxygen burners that use gaseous fuels such as natural gas or fossil solid fuels as fuel. device. The glass raw material is melted by the flame ejected from the burner. After the raw material is melted, the formed glass melt is fully clarified, and then taken...

The invention discloses a method for controlling the position of foam on the surface of a glass melt: select a number of predetermined monitoring points on the surface of the glass melt; monitor whether there is foam at the predetermined monitoring points; adjust the glass furnace according to the position of the foam The ratio of the first fuel and the second fuel added in; wherein, the first fuel is a gaseous fuel, and the carbon content of the second fuel is higher than that of the first fuel. The method provided by the invention can adjust the position of the foam on the surface of the glass melt, especially can digitally regulate the position of the boundary line of the bubble. By monitoring the extension of the foam on the surface of the glass melt along the flow direction of the glass liquid, the ratio of the two fuels is adjusted to control the position of the bubble boundary; through the foam position sensor, the signal for adjusting the fuel ratio is given in stages to control the movement of the bubble boundary .
Description
technical field [0001] The present invention relates to a method for controlling the position of foam on the surface of molten glass, in particular to a method for monitoring and adjusting the position of foam on the surface of molten glass in a glass furnace, especially using a sulfur-containing heat source Or the control of the foam position on the glass melt surface during the melting process of glass containing sulfur formula. Background technique [0002] In the process of glass production, because silica sand, sulfate, carbonate and other raw materials will release SO in the process of pyrolysis and melting 2 、H 2 O.CO 2 Other gases A large number of gases, and some gases, are naturally carried by batch materials or introduced into molten glass by combustion heat sources such as sulfur-containing petroleum coke or coal dust. Most of the gas has escaped in the initial molten phase, but some is trapped in the melt to form dispersed gas inclusions, so-called gas bubble...
