Optimizing Glass Manufacturing
Reduce energy use and emissions with Linde's OPTIMELT waste heat recovery technology.
Glass making is an ancient process - but producing it has never been more challenging.
Today, manufacturers are faced with the challenges of reducing energy use and emissions while increasing output and maintaining quality. The melting process alone accounts for up to 80% of total energy use. While switching from air to oxygen can significantly reduce fuel consumption, we went further.
With OPTIMELT, Linde captures and reuses wasted heat - helping furnaces run more efficiently and sustainably.
The results:
- Up to 30% lower fuel consumption
- Reduced CO2 and NOx emissions
- Improved heat transfer and glass quality
- Lower peak temperatures, extending furnace life
While Linde is a leader in oxygen supply for oxyfuel furnaces, we also support the industry more broadly — helping glass manufacturers overcome their toughest challenges.
