driven gas turbine manufacturers to develop combustion systems that create lower and lower emissions of nitrous oxides (NO x), carbon monoxide (CO) and unburned hydrocarbons (UHC). To meet this challenge, manufacturers developed Dry Low Emissions (DLE) or Dry Low NO x (DLN) combustion systems. Primarily
State-of-the-art emissions control technology for heavy-duty gas turbines is reviewed with empha-sis on the operating characteristics and field experience of Dry Low NOx (DLN) combustors for E and F technology machines.
Development of the DLE Combustor for L30A Gas Turbine
Aug 12, 2015 · This paper describes the development of the Dry Low Emission (DLE) combustor for L30A gas turbine. Kawasaki Heavy Industries, LTD (KHI) has been producing relatively small-size gas turbines (25kW to 30MW class).
Enlarging Fuel Flexibility for Frame 5 DLN: Combustor …
Aug 12, 2015 · Fuel flexibility is a key feature for Dry Low NOx (DLN) combustors, which shall be capable of accepting a wider range of fuel compositions to meet more and more challenging requests from the Oil and Gas market segment (upstream and downstream applications).

Development of the DLE Combustor for L30A Gas Turbine
Jun 15, 2015 · In this paper, we analyzed advanced ground-based power gas turbine units with low-emission combustion chambers used for consecutive two-stage fuel combustion.
Modern DLN combustors must operate within tight tolerances of fuel/air ratio, fuel/air mixing and heat release rate in order to deliver single digit NO x performance with combustion stability and design power output.
DLN Combustor - Multiple fuel nozzles per combustor with a numerous small metering and discharge orifices to achieve precise fuel/air ratio control – small size
Combustion Tuning for State-of-the-Art Combustion Turbines
Combustion tuning is critical for successful operation of modern combustion turbine generators equipped with state-of-the-art DLN combustion systems. Tuning performed by qualified combustion systems engineers and technicians can be augmented by integrating CDMS into combustion turbine controls.
Difference Between Standard Combustor and DLN Combustion
Sep 22, 2014 · DLN combustors are very different in that they force the majority of air to the fuel nozzle area of the combustor to premix with fuel and combust at a much lower temperature that doesn't require so much cooling and dilution air before entering the turbine nozzles.
