Fuel supply conduit assemblies

A combustor comprising:

• a sleeve assembly defining a combustion chamber;
• a secondary fuel injector coupled to said sleeve assembly such that said secondary fuel injector is in flow communication with said combustion chamber;
• an injector housing surrounding said secondary fuel injector;
• and
• a conduit assembly radially outward of said sleeve assembly and coupled to said secondary fuel injector for supplying fuel to said secondary fuel injector, wherein said conduit assembly comprises:
• a first conduit for supplying the fuel to said secondary fuel injector;
• a second conduit circumscribing said first conduit to define a channel between said first conduit and said second conduit;
• wherein said first conduit and said second conduit terminate within said injector housing.

A turbine assembly comprising:

• a turbine;
• and
• a combustor coupled in flow communication with said turbine, wherein said combustor comprises:
• a sleeve assembly defining a combustion chamber;
• a secondary fuel injector coupled to said sleeve assembly such that said secondary fuel injector is in flow communication with said combustion chamber;
• an injector housing surrounding said secondary fuel injector;
• and
• a conduit assembly radially outward of said sleeve assembly and coupled to said secondary fuel injector for supplying fuel to said secondary fuel injector, wherein said conduit assembly comprises:
• a first conduit for supplying the fuel to said secondary fuel injector;
• a second conduit circumscribing said first conduit to define a channel between said first conduit and said second conduit;
• wherein said first conduit and said second conduit terminate within said injector housing.
