Flat glass

Oxygen for glass melting

Boosting productivity through combustion-air enrichment

In recent decades, the glass industry has sought to improve the efficiency and productivity of its furnaces. One solution for enhancing the melting process is enriching combustion air with oxygen.

The oxygen-air mixing system is designed and customized according to process requirements: it ensures correct and rapid gas homogenization and uniform distribution of the mixture inside the furnace.

We work with customers to determine the most suitable and efficient installation position for the mixing system, thereby maximizing the benefits achieved.

Port-zero oxyboosting

Maximizing production and improving glass quality with oxygen burners

Oxyboosting makes it possible to increase production and improve glass quality while reducing CO2 emissions, through the installation of specially designed SIAD burners that ensure efficient and homogeneous glass melting.

Careful selection of the burner position is essential for the success of the application. We ensure precise control of the fuel and oxidizer flow rates to the burners, maintaining the correct combustion ratio. In addition, the control system provides maximum safety and reliable process operation.

In the flat glass forming process, one of the critical elements is the protection of the tin bath. The formation of tin oxides can cause defects such as inclusions, streaks or stains on the glass surface, compromising product quality.

The presence of a protective atmosphere inside the furnace is essential to ensure an optimal glass finish and prevent the formation of unwanted defects. We propose the use of a nitrogen and hydrogen mixture as a protective atmosphere.

Nitrogen inertizes the atmosphere inside the tin bath chamber. This creates an oxygen-free environment that prevents oxide formation. As an inert gas, nitrogen does not react with the other components.

Hydrogen is introduced to react rapidly with the oxygen present due to air infiltration, resulting in the formation of water. This prevents the formation of tin oxides, ensuring maximum product quality.
