ZEECO duct burners are installed in combustion turbine facilities around the world, including flue gas reheat systems for SCR NOx reduction and air heating applications.
Zeeco Duct Burner System Upgrades and Retrofit Program.
Zeeco’s DB-LN burner series minimizes emissions while maximizing fuel flexibility and energy efficiency to provide reliable supplementary firing for power and steam generation. The ZEECO® duct burner uses a self-supporting design and does not require any mid span support structure. Each firing element and flow baffle is designed to grow and expand independently. This design extends equipment life in the high temperature and turbulence downstream of a combustion turbine.
Common Industry Challenges
- Imbalanced flame patterns leading to imbalanced boiler heat absorption
- Sagging or binding firing elements
- Warped or corroded flame stabilizers
- Warped or corroded duct liners
- Ineffective ignition systems
- Ineffective scanner locations and technology
- Ineffective distribution grid systems
- Improper velocity and air/exhaust gas mixing
- Improper flame length
- Warranty issues and poor equipment performance
