Pure Oxygen Top Firing Technology To Increase Efficiency And Reduce Emissions And Create Benefits

Natural gas pure oxygen top combustion technology is different from the traditional parapet pure oxygen open burning, the difference is that the open burning depends on the energy exchange of heat radiation, while the pure oxygen top burning is based on the principle of vertical and directional direct heating, which improves the heat transfer rate of the compound, thus improving the melting rate.

Continuous cost reduction, efficiency, emission reduction to improve product quality is an effective means for the competitiveness of the daily glass industry. The introduction and application of pure oxygen top combustion and electric melting technology in the kiln is an important measure to promote the structural adjustment and industrial upgrading of the daily glass industry, and strengthen energy conservation and emission reduction and comprehensive utilization of resources. In recent years, with the development of kilns to large-scale, green, energy-saving, high-quality and efficient direction, kiln pure oxygen combustion technology is more and more applied in the daily glass industry, in the second half of 2022 and the first half of 2023, we investigated the use of some enterprises in the industry that apply pure oxygen combustion technology.

Application of auxiliary electric melting technology in the production of daily glass.

The auxiliary electric melting technology refers to the use of electrodes to directly feed electric energy into the glass furnace heated by fuel, directly energize to supplement a part of the heat required for melting, and the incoming electrical energy acts on the melting with an efficiency of more than 95%. The main functions can be divided into the following points:
1, it can be used as an economic method to increase the output of pond kiln, widely used in large pond kiln. According to the different varieties of glass, the melting rate increased from the initial 1.8T/㎡ to 3.2T/㎡.d, the melting area remained unchanged, and the melting rate increased by more than 60%.
2, due to the introduction of multi-row and multi-electric melting, the flow of glass liquid is strengthened to improve the uniformity of glass. The reflux of the glass liquid in the furnace is increased, the retention time of the glass liquid in the furnace is extended, the retention time is increased by 30% compared with the bubbling, the glass quality is improved, the stones, streaks, bubbles and so on are basically eliminated, and the finished product rate is a higher level.
3, flexible adjustment of the amount of material, can quickly adjust the capacity of the pool kiln according to market demand, suitable for the kiln that needs to change the amount of material.
4, more suitable for color glass or refractory glass.
