Energy Saving Methods For Float Glass (2)

Energy conservation in glass enterprises is a long-term task, and technical personnel at home and abroad are actively conducting research, such as optimizing kiln structure design, oxygen rich combustion, full oxygen combustion electric melting, heavy oil emulsification technology, etc. Many enterprises have started implementing energy-saving measures in the production process and exploring energy-saving measures in glass production process control and other aspects.
The moisture content, temperature, and fuel consumption of the batch are well-known, and the state of moisture in the batch is closely related to the temperature of the batch. When the temperature of the batch exceeds 35 ℃, the vast majority of water adheres to the surface of refractory sand particles in a free state, which can enhance the melting effect by adhering more pure alkali. When the temperature of the batch is less than 35 ℃, the moisture in the batch will form Na2CO3 · 10H2O or Na2CO3 · 7H2O with soda ash, and form Na2SO4 · 10H2O crystalline water compounds with mirabilite, causing the surface of the sand particles to lose moisture and appear dry, weakening the melting effect.
In winter, due to lower temperatures, the temperature of the mix in northern regions is generally lower than 35 ℃, and in some areas it is only around 20 ℃. In order to keep the appearance of the batch moist, it is usually adopted to increase the moisture content of the batch. Although it has a certain effect, it can also bring many drawbacks, such as increased agglomeration on the silo wall and increased fuel consumption. Someone calculated that the amount of oil required to enter the kiln for water is 0.085kg of oil/kg of water.
