O L U T I O N S F-CLASS GAS TURBINES 6F.03, 7F, and 9F DLN 2.6+


Combustion Solution THE NEXT GENERATION OF TECHNOLOGY LEADERSHIP


Extend your outage intervals and flexibility with GE’s Dry Low NOx


(DLN) 2.6+ combustion system. Building on a rich


heritage of combustion leadership, the DLN2.6+ delivers industry-leading low emissions. Introduced in 2005 on 9F gas turbines, the DLN2.6+ is now available for 7F units (DLN2.6+ for 6F units is set to be released in 2018). Key advantages of this system include:


• Reduced NOx emissions to as low as 5 ppm for the 7F, 10


ppm for 9F.03, and 15 ppm for 9F.04—across large load and an ambient temperature range of 0° F–120° F


• Increased availability and lower maintenance costs due to 32,000 FFH and 1,200 FFS 9F combustion intervals and 1,250 FFS for 7F combustion intervals


• Broadened fuel flexibility for gas fuels with up to 30% Modified Wobbe Index (MWI), 25% ethane/propane, 20% hydrogen, and a wide range of distillate fuels


• Extended turndown to as low as 37%(7F) and 32% (9F) of baseload for off-peak fuel savings and fast dispatch


• Enhanced performance and operability advantages of the Advanced Gas Path and Advanced Compressor

• Improved flexibility when combined with OpFlex controls software, including AutoTune, Fast Start, Cold-Day Performance, and Extended Turndown


• Reduced costs due to the elimination of diluent injection or Selective Catalytic Reduction (SCR) systems and the drawbacks associated with ammonia utilization
