In glass manufacturing, an industry with a long history and continuous innovation and development, clay bricks play a pivotal role in every key link. Its unique physical and chemical properties make it an indispensable material for ensuring efficient and stable glass production, as well as ensuring the high quality of glass products.
1. Regenerative chamber
The regenerator of glass melting kiln is the key part to realize the efficient utilization of energy, and the clay brick is the core material to construct the regenerator. In the glass production process, the high-temperature flue gas temperature generated by the furnace combustion can reach 1500℃ or even higher. When these high temperature flue gases pass through the regenerator, the clay brick can absorb a lot of heat in the flue gas and store it by virtue of its high specific heat capacity and good high temperature resistance. Subsequently, when the cold air enters the regenerator, the clay brick releases the stored heat to the cold air, so that the cold air quickly heats up to about 1000 ° C, and then enters the melting kiln to participate in the combustion.
This heat exchange process greatly improves energy utilization efficiency, reduces fuel consumption, and reduces production costs. At the same time, the chemical stability of the clay brick makes it able to maintain the integrity of the structure under the condition of long-term high-temperature gas erosion, ensure the stable operation of the regenerator, and provide a strong guarantee for the continuous and efficient production of the glass melting kiln.
2. The flue system
In the flue system of glass melting kiln, clay bricks also play a vital role. The flue is responsible for discharging the exhaust gas produced by the melting kiln, and its internal environment not only has a high temperature, but also contains a certain amount of corrosive gases and dust. Clay brick has good corrosion resistance and wear resistance, which can effectively resist the erosion and erosion of acidic gas and dust in the exhaust gas, prevent the damage of the flue wall, and ensure the smooth flow of the flue.
In addition, the thermal insulation properties of clay bricks also help to reduce the heat loss of the flue system, avoid the impact of high temperatures on the surrounding environment, and improve the thermal efficiency of the entire furnace system. Reasonable selection and laying of clay bricks can extend the service life of the flue, reduce maintenance costs, and ensure the stability and safety of exhaust emissions in the glass production process.
3. Glass annealing kiln
Glass annealing is the key process to eliminate the internal stress of glass products and improve product quality, and the annealing kiln is the equipment to complete this process. Clay brick in annealing kiln is mainly used for laying kiln structure and as heat insulation material. The good thermal insulation performance of clay brick can maintain a stable temperature field in the annealing kiln, ensure that the glass products in the slow and uniform cooling process, effectively eliminate the internal stress, avoid the appearance of cracking, deformation and other defects, and improve the yield and quality of glass products.
At the same time, the mechanical strength of the clay brick can support the structure of the annealing kiln, so that it can remain stable during long-term temperature changes and equipment operation, and provide a reliable physical space for the smooth implementation of the glass annealing process.
Clay bricks play an irreplaceable role in the key parts of the glass industry such as regenerator chamber, flue system and annealing kiln. With the technical progress of the glass industry and the continuous improvement of energy conservation and environmental protection requirements, higher requirements are also put forward for the performance of clay bricks. In the future, through continuous research and development and innovation, further optimizing the performance of clay bricks will make it better serve the glass industry and promote the sustainable and healthy development of the glass industry.
