Embodiment Construction

[0015] The exemplary apparatus, systems, and methods described herein overcome at least some of the known disadvantages associated with at least some known turbine engine combustion systems that introduce vibrational energy therein and / or down operation. Embodiments described herein provide a fuel injection assembly that may be used with a turbine engine to facilitate substantially reducing dynamic pressure oscillations and / or localized peak temperatures within a combustor. The fuel injection assembly includes a plurality of tube assemblies, where each tube assembly of the plurality of tube assemblies includes a plurality of tubes. At least one injection system is coupled to at least one tube assembly of the plurality of tube assemblies. The injection system includes a fuel delivery conduit and a fluid supply member coupled to the fuel delivery conduit, wherein the fluid supply member is positioned at a distance upstream relative to the tube assembly. The fluid supply member...

Abstract

A fuel injection assembly for use in a turbine engine is provided. The fuel injection assembly includes a plurality of tube assemblies wherein each of the plurality of tube assemblies includes a plurality of tubes. At least one injection system is coupled to at least one tube assembly of the plurality of tube assemblies. The injection system includes a fuel delivery pipe and a fluid supply member coupled to the fuel delivery pipe, wherein the fluid supply member is positioned a predefined distance upstream from the tube assembly and includes at least one first portion having an annular end portion. The annular end portion includes at least one opening for delivering fluid toward the tube assembly for reducing dynamic pressure oscillations and / or reducing the temperature within a combustor during operation of the turbine engine.

Description

technical field [0001] The subject matter disclosed in this specification relates generally to turbine engines, and more particularly, to fuel injection assemblies for use in turbine engines. Background technique [0002] At least some known turbogenerators are used in cogeneration facilities and power plants. Such engines may have high demands on specific work and power per unit mass flow. Such a turbine engine may include at least one combustor including a plurality of fuel nozzles that may be coupled within the combustor. Compressed air flows through and through the nozzles to reach the combustion zone within the combustor. As the air travels through and past the fuel nozzles, fuel is injected into the air stream, and the air and fuel mix together to create a fuel-air mixture that is ignited in the combustion zone of the combustor. To increase operating efficiency, at least some known turbine engines, such as gas turbine engines, operate at elevated combustion temperat...
