Dry Emission Reduction
Case Studies
Duke Energy – New Albany Plant
- Plant located in New Albany, Mississippi, Contract awarded Dec. 1998, Start-up April 1999
- Originally constructed for Enron International by TTS
- Unit Relocations – Six (6) GE Frame 7B units from Korea to the US
- Units initially operating on liquid fuel, firing at 1865°F

- Units converted to gas fuel low NOX combustors, increased firing temperature to 1965-2020°F
- Upgrades included: Fuel control system design and install, TTS Control System, and low NOX system control sequencing
- Units operated below 15 ppm NOX
