Abstract

The invention relates to a system for conditioning air flow into a multi-nozzle assembly. A system includes a turbine fuel nozzle assembly. The turbine fuel nozzle assembly includes a first fuel nozzle including a first air inlet and a second fuel nozzle including a second air inlet. The turbine fuel nozzle assembly also includes a first inlet flow conditioner disposed adjacent the first air inlet of the first fuel nozzle, wherein the first air inlet flow conditioner extends only partially around the first fuel nozzle. The turbine fuel nozzle further includes a second inlet flow conditioner disposed adjacent the second air inlet of the second fuel nozzle, wherein the second air inlet flow conditioner extends only partially around the second fuel nozzle, and the second inlet flow conditioner is separate from the first inlet flow conditioner.

Description

technical field [0001] The subject matter disclosed herein relates to gas turbine engines, and more particularly, to systems for regulating airflow into a multi-nozzle assembly. Background technique [0002] Fuel-air mixing can affect engine performance and emissions in various engines, such as gas turbine engines. For example, a gas turbine engine may employ one or more fuel nozzles to intake air and fuel to facilitate fuel-air mixing in the combustor. Additionally, each of these fuel nozzles may include multiple tubes for fuel-air mixing. Fuel nozzles may be located in the head end portion of the combustor and may be configured to draw in a flow of air to be mixed with the flow of fuel. Unfortunately, air may not be evenly distributed to the individual tubes within each fuel nozzle, thereby affecting overall engine performance, emissions, and flame holding margin. Contents of the invention [0003] Certain embodiments commensurate in scope with the originally claimed ...
