The Industry Challenge

To heat glass furnaces, air is commonly used to provide oxygen for combustion. However, when a glass furnace ages, several challenges emerge, such as maintaining the pull rate, extending the furnace campaign, or even repairing air regenerators.

If greater capacity is needed, adding oxy-fuel burners in a glass furnace is the best way to boost the pull rate up to 10%.

For the most suitable solution to compensate furnace aging and maintain productivity, discover Nexelia™ for Melting Oxy-Boosting. Additionally, it helps increase glass production and address environmental concerns for your growing business.

Nexelia™ for Melting Oxy-Boosting

Based on our groundbreaking technology, Nexelia™ for Melting Oxy-Boosting uses pure oxygen instead of air combustion, offering optimal glass-melting conditions by improving heat transfer.

You have three options to choose from:

  • air enrichment to continue using air burners while increasing the oxygen concentration in combustion air (typically up to 24%),
  • oxy-boosting, which directly funnels pure oxygen through one or several lances inserted in or close to the air burners,
  • additional oxy-fuel burners, which can be installed when a glass furnace needs a high or higher heat transfer, temporarily or continuously.

Nexelia™ for Melting Oxy-Boosting provides you the optimal expertise and experience.

Your benefits of Nexelia™ for Melting Oxy-Boosting:

  • pull increases up to 10%,
  • furnace life time extension,
  • full support of our glass experts at every step, from the auditing of your current melting process to the preliminary and detailed designs of your new solution, as well as its complete implementation, including commissioning, monitoring and maintenance.

Application equipment

For optimal melting oxy-boosting, Air Liquide provides you the following equipment:

  • lances,
  • patented burners,
  • valve trains.

Modeling services

  • AIRLOG is a 0D mass- and energy-balance calculation tool which verifies that oxy-combustion is viable thanks to first feasibility studies.
  • ATHENA 3D allows a complete description of flows and heat transfer within the combustion chamber and the glass bath in aero-combustion, as well as in oxy-combustion. It helps validate the right choices, especially when converting a glass furnace to oxy-combustion.
