Glass

Industrial Gas Supply & technology for the glass industry

Making glass clearly cleaner

The action of making glass is over 5,000 years old, but two decades ago, Praxair made great strides in getting this ancient craft ready for the twenty-first century. 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 today’s regulatory requirements. Our burners 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

Glass Melting

Glass Melting 

With our 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

Our 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

Our portfolio 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 

Our 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.

OPTIFIRE XD burner

OPTIFIRE XD Burner

The OPTIFIRE XD burner is an extreme duty burner designed to offer a continuous, low-momentum flame. The XD burner performance has proven successful in mitigating condensate build-up around the cooler oxygen ports and offers a quick-release feature for easy installation and removal of internal burner components.

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.
