System for dissipating fuel egress in fuel supply conduit assemblies
Abstract
A system for dissipating fuel egress includes a fuel injector and a fuel supply assembly. The fuel supply assembly has a fuel supply line that provides fuel and a purge air conduit arranged co-axially around the fuel supply line, thereby defining an annular channel around the fuel supply line. The fuel injector includes a perimeter body, a fuel injection port associated with the perimeter body, and an internal mixing chamber downstream of the fuel injection port in a direction of fuel flow. The fuel supply line provides fuel to the fuel injection port. The perimeter body of the fuel injector defines a fuel egress passage therethrough, which has an inlet in fluid communication with the annular channel and an outlet in fluid communication with the mixing chamber. A gas turbine combustor having an axial fuel staging (AFS) system with the present fuel egress dissipation system is also provided.
