F-Class DLN Technology Advancements: DLN2.6+

GE’s DLN2.6 system opened the doors to single digit NOx emissions for F-Class industrial gas turbines. Today more than 500 DLN2.6 systems are installed worldwide. GE has recently advanced the technology of F-Class “Dry Low NOx ” (DLN). The new DLN2.6+ technology achieves low-NOx emissions for 9FA and 9FB turbines. Turndown in NOx and CO compliance for 9FB turbines to 32% load and 9FA turbines to 28% load has been demonstrated in the field. This paper will summarize the development history of DLN2.6 and 2.6+ combustion systems and the operating experience of the DLN2.6+. Field validation performance results of the systems will be shared as well as fuel-flexibility results with the DLN2.6+ system.Copyright
