[China Glass Network] As we all know, the structural design of glass melting furnace has great influence on heat exchange efficiency, energy consumption and glass liquid quality. Due to different design schemes, energy consumption can vary by 30%. The improvement of heat exchange efficiency not only reduces energy consumption, but also saves production costs, and also promotes the formation of reasonable circulating convection of the molten glass and improves the clarification quality of the molten glass.
In recent years, people have a deeper understanding and understanding of the glass melting process, and environmental awareness is constantly increasing. Countries around the world have strengthened environmental protection legislation to limit the emissions of dust, NO-SO: and F: in glass furnace flue gas. In order to meet these environmental standards, some companies use flue gas treatment methods for traditional kiln to reduce the concentration of dust and harmful components and meet environmental emission standards. Some companies use new technology, such as improving glass formulation and glass composition, limiting sulfur content in fuels, using low NOx combustion technology, using pure oxygen combustion technology, using full fused technology or electric fluxing technology, etc. Advanced technology has promoted the improvement of glass technology to a certain extent.
In recent years, a new type of pool furnace structure has emerged abroad, separating the melting process from the clarification process. The batch material is melted into the cold-top all-electric bath furnace, and the batch material is melted into glass and then enters the flame melting furnace for high temperature. Clarification of homogenization, combining the advantages of an all-electric melting furnace and a flame kiln. This type of kiln prevents the batch from coming into contact with the flame, reduces dust and volatile components, reduces blockage of the lattice, and reduces the interaction between the melting process and the clarification process to a lesser extent.
Glass fiber kiln, advanced pool bottom electric fluxing technology and application of various bottom bubble technology, advanced combustion technology application, boron-free fluorine-free glass formulation, these technologies are directly or indirectly improved The stability and uniformity of the composition of the glass liquid promotes the improvement of the liquid liquid w+.
The uniformity of the temperature of the glass liquid is inseparable from the structural design of the channel and the temperature adjustment method. In order to uniformly reduce the clarified glass liquid to the required forming L: art temperature, the upper space is adjusted with a gas premixed combustion temperature to make the temperature uniformity of the glass liquid better, and the channel K degree is usually above s meters. . At present, many glass fiber channels, glass wool channels, glass pipe channels, and some glass products are used in this temperature regulation.
