Fuel injection assembly for use in turbine engines and method of assembling same

A turbine engine, said turbine engine comprising:

• a compressor;
• a combustion assembly coupled downstream from said compressor, wherein said combustion assembly comprises at least one combustor comprising a fuel injection assembly comprising:
• a plurality of tube assemblies wherein each of said plurality of tube assemblies comprises a plurality of tubes;
• and
• at least one injection system coupled to at least one tube assembly of said plurality of tube assemblies, wherein said at least one injection system comprises a fuel delivery pipe and a fluid supply member coupled to said fuel delivery pipe, wherein said fluid supply member is positioned a predefined distance upstream from said at least one tube assembly and comprises at least one first portion comprising an annular end portion, wherein said annular end portion comprises at least one opening for delivering fluid toward said at least one tube assembly for reducing at least one of dynamic pressure oscillations and temperature within said combustor during operation of said turbine engine.

A method for assembling a fuel injection assembly for use with a turbine engine, said method comprising:

• providing a plurality of tube assemblies wherein each of the plurality of tube assemblies includes a plurality of tubes;
• coupling at least one injection system to at least one tube assembly of the plurality of tube assemblies, wherein the at least one injection system includes a fuel delivery pipe and a fluid supply member coupled to the fuel delivery pipe, wherein the fluid supply member includes at least one first portion having an annular end portion, wherein the annular end portion includes least one opening for delivering fluid toward the at least one tube assembly for reducing at least one of dynamic pressure oscillations and temperature within a combustor during operation of the turbine engine;
• and
• positioning the fluid supply member a predefined distance upstream from the at least one tube assembly.
