Low NOx combustor retro-fit system for gas turbines

The gas turbine comprises a compressor for producing compressed air. A cylinder casing receives the compressed air from the compressor. The cylinder casing has an aperture and a combustor in which a fuel is burned in the compressed air to produce a hot gas. The combustor is disposed within the cylin...

Beschreibung
Zusammenfassung:	The gas turbine comprises a compressor for producing compressed air. A cylinder casing receives the compressed air from the compressor. The cylinder casing has an aperture and a combustor in which a fuel is burned in the compressed air to produce a hot gas. The combustor is disposed within the cylinder casing. A nozzle block has fuel nozzles for spraying the fuel into the combustor. The nozzle block has a pilot nozzle aperture and first and second ends. The first end is mechanically affixed to the combustor such that the fuel nozzles extend into the combustor. The second end is mechanically affixed to the cylinder casing. The nozzle block has fuel passages in flow communication with the fuel nozzle. A fuel supply has manifold passages in flow communication with a supply of fuel.
