Nexelia™ for Combustion

An innovative technology that consists of preheating oxygen and natural gas at high temperature generated by combustion fumes.

Industry Challenge

The glass industry is under severe cost constraints and increasing environmental pressure to reduce emissions. Air Liquide provides glass manufacturers with solutions to improve their competitiveness and environmental footprint.

As long standing experts in oxy-combustion, which is the process of burning a fuel using pure oxygen instead of air as the primary oxidant, we have substantial R&D resources and a strong experience in glass making thanks to our extensive network of field experts.

Nexelia™ for Melting-Heat Oxy-Combustion

Air is commonly used to provide oxygen for combustion to heat industrial furnaces. Oxy-combustion is based on the enrichment of air with pure oxygen to improve the overall energy efficiency of glass-melting process.

Nexelia™ for Melting-Heat Oxy-Combustion is an innovative technology that consists of preheating oxygen and natural gas at high temperature generated by combustion fumes. Compared to oxy-combustion without preheating, it reduces fuel and oxygen consumption to the extent that oxy-combustion is economically beneficial to all types of glass. 

Nexelia™ for Melting-Heat Oxy-Combustion is suitable for container, technical and float glass furnaces.

Nexelia™ for Melting Oxy-Combustion

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

Air is commonly used to provide oxygen for combustion to heat industrial furnaces. Oxy-combustion is based on the enrichment of air with pure oxygen to improve the overall energy efficiency of the glass-melting process.

In addition to premium expertise and experience, from oxygen supply to the optimization of the combustion, you’ll benefit from equipment and services linked to proprietary new technologies in oxy-fuel glass melting.

Nexelia™ for Melting Oxy-Combustion is well suited for all types of glass, including insulation glass, reinforcement fiber, lighting glass and other technical and container glass.

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.

Nexelia™ for Glass Finishing

Finishing enables the superficial remelting of the glass article to eliminate any forming defects to increased value of your glass articles. Finishing also significantly increases quality by reducing the number of defects and rejects, thus increasing production rate. The oxy-combustion faster firing time for each article, ensuring a reduction in fuel consumption by as much as 80%.

Based on our groundbreaking technology, Nexelia™ for Glass Finishing uses pure oxygen instead of air, offering transformation of plain-looking glass containers into prestige final products while ensuring outstanding performance, safety and environmental protection.
