Abstract

A system includes at least one component of a turbine section (22). The at least one component includes a fuel port (56) formed into a wall (111) of the at least one component, which is configured to inject fuel (52) into a chamber (94) of the turbine section. The at least one component also includes an inert gas port (57) formed into the wall upstream of the fuel port. The inert gas port is configured to inject an inert gas (54) to flow at least partially around the injected fuel in a buffer region (228) downstream from the fuel port. The presence of the inert gas in the buffer region may mitigate an ignition of the fuel near the surface of the wall downstream of the fuel port (e.g., flame anchoring) and/or help to lift the flame from the ignited fuel into the hot gas flow path.
