Duplex eliminates potential flame impingement.
Duplex essentially turns a single large and unruly flame into thousands of tiny, more easily controlled flames. Duplex burner architecture controls and reduces flame length and offers a number of potential improvements to operations, including:
- Reduced operating costs: no external flue gas recirculation, no high O2 levels and/or no selective catalytic reduction.
- Increased thermal capacity: heaters may be fired at higher rates to optimize total plant output.
- More complete mixing: a more balanced fuel/air blend to virtually eliminate NOx-forming species.
- Reduced maintenance costs: less de-coking, lower failure rates and longer lifetimes.
