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
Our Dilute Oxygen Combustion (DOC) technology for glass melting is based on the injection of fuel and oxygen through separate burner ports. This industrial application eliminates most of the nitrogen in combustion air and can help you lower NOx emissions by up to 90%, safe fuel costs, and improve your productivity.
This commercially demonstrated, revolutionary system recovers waste energy stored in regenerator checkers by preheating fuel and endothermically reacting the fuel with the CO2 and H2O in recycled flue gas. The result is conversion of fuel to hot syngas – delivering a net reduction in fuel required to melt your glass of 20% to 30% compared to oxy-fuel and air-fuel glass furnaces.
Industrial products for glass manufacturing, production and furnaces
OPTIFIRETM 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.
OPTIFIRETM 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.
OPTIFIRETM 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.
OPTIFLO2TM VPSA System
This oxygen supply system is especially designed to work with Praxair’s OPTIFIRE Wide Flame Burners. The system optimizes net power consumption, thus lowering your cost of oxygen. When combined with the OPTIFIRE Wide Flame Burner, you can have power savings resulting in cost savings over the duration of furnace campaign.
