As a global leader in the industrial gases industry, The Linde Group is the partner of choice for glass manufacturers. We can add value to your production processes by combining decades of experience in glass with market-leading, dedicated process innovations. We offer a wide range of gas applications, process technologies and services to cover all glass melting, forming and processing needs.
Melting
Using oxygen instead of or in addition to air in glass melting can eliminate the nitrogen ballast of air, dramatically reducing NOx formation and increasing flame temperatures.It also raises the concentration of CO₂ and H₂O in the vicinity of the flame. And since these gases are mainly responsible for thermal radiation, oxyfuel significantly increases thermal efficiency.
In particular, fuel consumption down by up to 50% due to improved heat transfer and lower flue gas heat losses; productivity rise up to 40% due to faster melting cycles. For the energy costs accounts for as much as 20 of overall costs, this saving helps to dramatically improve product cost.
Forming
Gases play an important role in the forming of float glass, where a nitrogen/hydrogen atmosphere is used to avoid oxidation of the tin to minimise the tin count on the glass. The success of forming hinges on consistent delivery of your selected ratio and volume flow (e.g. 95 N₂ / 5 H₂) and on a secure supply of high-purity gases (N₂ 5.0 and H₂ 3.0).
We can help ensure the success of your float glass production line with reliable supplies of nitrogen and hydrogen in the required purity levels, complementing this with cost-effective, safe and reliable flow control equipment for optimum results.Gases play an important role in the forming of float glass, where a nitrogen/hydrogen atmosphere is used to avoid oxidation of the tin to minimise the tin count on the glass.

Surface Treatment
Our HYDROPOX® flame-based solution offers a number of benefits in glass surface treatment for art & tableware (e.g. wine glasses), specialty glasses (e.g. display glasses) and high-value container glass (e.g. flacons). With its homogenous flame curtain, HYDROPOX® ensures an even heat transfer and briefly brings the glass surface to a temperature above the softening point of the glass, which helps to increase the brilliance of the glass surface, eliminate seams and edges and heal of micro-cracks and failures.
