Heating method of glass batch

Abstract

The invention discloses a heating method of a glass batch. In the process of heating and melting the glass batch, a glass kiln is used for heating and melting the glass batch into molten glass, wherein the glass kiln comprises a kiln side wall, a melting tank and a crown which is positioned above the melting tank and forms the top of the glass kiln, and a plurality of combustion spray guns are arranged at the bottom of the melting tank; and fuel in a combustion spray gun at the bottom of the melting tank is controlled to combust, and vertically upward flame is sprayed to heat and melt the glass batch into molten glass. The flame directly heats the glass batch in the glass batch, so that the volatilization amount of the volatile raw material can be reduced, and the content of each element in the finally formed glass product is ensured to be within a design range. Combustion products are generated in the glass batch, so that clarification of molten glass is facilitated; and the additionamount of a clarifying agent can be reduced, or even the clarifying agent is not added, so that the preparation cost of the glass can be reduced on the premise that the melting clarification quality of the molten glass is guaranteed.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to a method for heating glass batch materials. Background technique [0002] When producing refractory glass, such as high-alumina glass, high borosilicate glass, and glass-ceramics, it is very difficult to melt and clarify the glass, which needs to be solved by increasing the melting temperature, adopting a special melting method, and adding a clarifying agent to the glass batch. . Increasing the melting temperature will aggravate the flame damage to the breast wall and large wall in the glass furnace, resulting in a reduction in the life of the glass furnace; special melting methods will reduce the safety of the glass furnace; adding clarifiers will increase the glass production cost. [0003] At the same time, due to the high melting temperature of refractory glass and the alternate combustion of the combustion lances, in order to ensure the stability of the temperature...

Problems solved by technology

This will not only increase the cost of raw materials, volatile raw materials will enter the flue gas after volatilization, but also lead to an increase in the concentration of solid particles in the flue gas, resulting in blockage of the flue gas exhaust channel, increasing the load of flue gas dust removal, and increasing the production cost of glass
