The Industry Challenge

In today’s glass-production processes, energy consumption and gas emissions present major obstacles to sustainability and productivity. 

Whatever you need to optimize the operational costs of your melting process, Nexelia™ for Melting-Heat Oxy-Combustion is the optimal choice.

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.

Your benefits of Nexelia™ for Melting-Heat Oxy-Combustion:

  • 10% extra energy savings,
  • 10% extra CO2 emission reduction,
  • maximized oxy-combustion performance,
  • CAPEX reduction,
  • 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-heat oxy-combustion Air Liquide provides you the following equipment:

  • heat exchangers,
  • 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.
