What are the new technologies of glass furnace?

Nanjing Baisheng Glass Technology Co., Ltd. and Nanjing Baisheng Kiln Engineering Co., Ltd. were established in February 2006 and January 2014 respectively. Is a professional company engaged in glass factory (kiln) design, kiln (equipment) construction and installation and glass production technical services. The company mainly serves the glass factory design of flat glass, photovoltaic calendered glass, electric light source glass, daily-use glass, water glass and ceramic frit production lines, glass engineering installation and construction, firing and baking kiln, commissioning and related technical training, technical services, and professional companies for hot and cold repair of glass kilns.

1. With the help of computer simulation technology, it provides a numerical test platform for the development of energy-saving furnaces, reducing pollutant emissions and improving product quality.

2. —— The application of new structure melting furnace, such as stepped bottom structure, to further improve the glass flow, reduce reflux and "dead zone", realize energy saving and improve the glass quality;

3. —— Adopt fully sealed feeding port structure to reduce heat dissipation and dust, and improve pre-melting effect.

4. —— REDOX melting control is adopted to minimize bubbles in the molten glass, so that the clarification temperature or time can be appropriately reduced to achieve the purpose of energy saving and quality improvement.

5. Oxygen-enriched combustion technology Nitrogen produced by float glass factory is oxygen-enriched air, which is added to the furnace in different ways to participate in combustion, thus improving thermal efficiency, saving fuel and improving melting quality.

6. Deep Clarification and Homogenization Technology By bubbling the glass melt with compressed gas in the batch area or hot spot, the activation heat exchange process in the depth direction of the glass melt can be changed, which is helpful to shorten the formation time of silicate and glass, improve the homogenization of glass melt and stabilize the bubble boundary, and has obvious effect on producing high-quality float glass.

7. —— The auxiliary electric flux technology of glass furnace can be used not only to improve the production capacity and thermal efficiency of float glass furnace, but also to improve the homogenization of glass liquid.

8. —— Oxygen-assisted combustion technology (i.e., oxygen-assisted melting technology in No.0 small furnace): It is favorable for melting, which can improve the melting quality of molten glass and reduce the blockage of No.1 small furnace. Domestic glass production lines such as Huaguang have adopted it.

9. Flue gas desulfurization and dust removal technology of glass melting furnace Heavy oil is generally used as fuel for float glass industry in China. The sulfur content of heavy oil and mirabilite in glass batch lead to a large amount of sulfur dioxide in flue gas and air pollution. Under the circumstance of more and more strict environmental protection requirements, it is urgent to treat the flue gas desulfurization of glass melting furnace. Domestic production lines such as SYP Guangdong Float and Shenzhen CSG Float have adopted flue gas desulfurization technology and equipment, and achieved satisfactory results.

10. Power generation technology and equipment with waste heat from glass melting furnace waste gas takes about 30% of the heat coming into the furnace, and the usable part of waste heat accounts for 65-80% of the smoke loss. At present, most of this heat is directly discharged into the atmosphere. Realize the power recovery of waste heat resources of glass melting furnace, convert the heat energy in waste gas into clean "electric energy", increase the economic benefits of enterprises, reduce the emission of atmospheric pollutants, realize the win-win situation of economic benefits, environmental protection benefits and social benefits, and open up new opportunities.

11. A Road to Circular Economy in Float Glass Industry At present, the developed waste heat power generation technology suitable for the working characteristics and flue gas characteristics of glass furnaces has been applied in glass enterprises such as Guangdong Xinyi.

The company's professional technicians focus on the design and production technology of float glass, flat-drawn glass, calendered glass and photovoltaic calendered glass production lines, and have carried out bold innovation and transformation from 60t/d to 600t/d, from marten flame and transverse flame furnaces. In recent years, cold repair, baking, thermal insulation and hot repair of large-scale float and rolled glass furnaces are the main projects of the company.

Company's proprietary technology: energy-saving kiln design technology, kiln cold repair breast wall hanging hook brick top replacement, large crown overall lifting and lowering technology, "L" hanging wall design and installation, low-input raw material automatic batching system. The company takes "technology, innovation and service" as its purpose to create value for customers.
