Dry Low NOx (DLN) Combustion
GE has combustion system upgrades available for all frame sizes to help customers improve their gas turbine's operability and reduce emissions. The upgrades may include application of GE's highest technology DLN (Dry Low NOx) combustion systems that can provide NOx emissions to as low as 3ppmand turndown to as low as 35%.
Other upgrades allow customers to convert to differing fuel types or eliminate the need for steam injection where the steam may be more useful for an industrial application.
The DLN combustion system upgrades are directed toward changing government regulation and/or business needs for reduced emissions and also for elimination of costly diluent injection or Selective Catalytic Reduction (SCR) systems.
Patented, world-class, state-of-the-art combustion system
Elimination of water usage for NOx reduction for gas fuel operation
Achieving NOx emission reduction with no significant part life reduction typical of steam or water injection
Increased availability through extended combustion inspection intervals up to 24,000 hours or 900 starts
