What if you could reduce gas consumption by up to 25 percent while significantly lowering emissions, without modifying your existing lehr?
For glass manufacturers, improving energy efficiency and reducing emissions has become a strategic priority. Yet, many assume achieving these goals requires replacing the entire combustion system. It doesn’t.
The Porojet Burner from Pennekamp has been developed as a true plug-and-play solution for conventional annealing and decorating lehrs, regardless of the original manufacturer. It integrates directly into existing installations without requiring modifications to the lehr or its PLC.
Why does it make a difference?
- Up to 25 percent lower gas consumption
- Up to 80 percent reduction in NOx, CO, and NO emissions
- Premix combustion independent of lehr pressure for stable, efficient performance
- Four-stage power control, including Pennekamp’s unique Active Cooling Mode
- Extremely short flame for optimised heat distribution
- Virtually maintenance-free porous ceramic burner head
- Fully compliant with EN 746-2
- Hydrogen-ready (H₂) for future fuel flexibility.
As energy costs continue to rise and environmental regulations become increasingly demanding, every improvement in combustion efficiency matters.
The Porojet Burner provides glass manufacturers with a practical way to reduce fuel consumption, lower emissions, and enhance process performance while maximising the value of their existing lehrs.
Lower fuel consumption. Cleaner combustion. Greater operational efficiency.
