Glass

Industrial Gas Supply & technology for the glass industry

Making glass clearly cleaner

The action of making glass is over 5,000 years old. At Linde, we have made great strides to improve this ancient craft in a way that meets today's goals of energy conservation, productivity, quality and emissions. With our full range of industrial gases, technologies and equipment, we successfully converted the first large container glass furnace to an oxy-fuel burner. This development was good news not just for our customers, but also for the planet. Oxy-fuel melting improves glass quality and helps you save money by burning less fuel more efficiently. It also drastically reduces NOx emissions to help you meet strict regulatory requirements. Our technologies allow you to produce a glass so clear and efficient that it could only be centuries in the making.

INDUSTRIAL APPLICATIONS FOR GLASS MANUFACTURING, PRODUCTION AND PROCESSING

Linde Glass Window Insulation

Glass Pane Insulation

Argon gas is used to insulate thermal windows. The use of argon increases the energy efficiency and general performance of of the windows. Argon helps to minimize heat exchange through the window in the summer and reduces the possibility of condensation and frost in the winter.

Glass Melting

Glass Melting 

Linde's OPTIFIRE™ family of burners with oxy-fuel melting technology, you may increase your process efficiency and productivity while reducing emissions. The use of oxygen, instead of or in addition to air, can decrease your fuel consumption and increase your productivity due to faster melting cycles.

OptiMelt

Waste Heat Recovery

Linde's OPTIMELT™ systems for waste heat recovery in the glass industry are designed to provide substantial reduction in energy consumption and carbon dioxide emissions, when compared to air regenerative and oxy-fuel furnaces. 

Oxyservice Oxygen Supply

Oxygen Service Offerings

Linde's oxygen service portfolio for glass gives you options to enhance the process efficiency of your air-fuel furnaces by using Oxygen Enhanced NOx Reduction, Zero-port Boosting, Reverse Hot Spot Boosting, or Oxygen Support Services.

HYDROPOX GLASS SURFACE

Glass Surface Treatment 

HYDROPOX® glass surface treatment is a flame-based system that offers several benefits for the glass industry. The system is designed to run on either oxygen and hydrogen or oxygen and natural gas, depending on your specific requirements. This results in increasing brilliance of the glass surface and the elimination of seams and edges. 

Glass Forming

Glass Forming

CARBOFLAM® carbon mold coating for glass formations offers many benefits compared to alternative methods for surface coating. These include reproducible coating results, stable temperature profile of the blank molds, and reduced maintenance and cleaning effort.

Industrial products for glass manufacturing, production and furnaces

Linde's OPTIFIRE Burners
OPTIFIRE WF Burner Gen III

OPTIFIRE WFB, Gen III

The OPTIFIRE WFB, Gen III is the newest version of the oxy-fuel wide flame burner. It offers high flame coverage and luminosity, helps reduce NOx and particulates emissions, and effectively produces a low momentum flame to minimize volatilization with no maintenance required.

OPTIFIRE JL burner

OPTIFIRE JL Burner

The OPTIFIRE JL burner is ideal for large area coverage. This burner is based on our innovative Dilute Oxygen Combustion technology and offers reduced glass furnace emissions. With proper placement, the burner minimizes alkali volatilization and particulate formation from the glass melt, which significantly reduces furnace refractory corrosion and promotes longer furnace life.
