Abstract

A system includes a web plate (36) axially disposed between a transition piece (32) and a turbine nozzle (34). The web plate (36) includes a radial arm (114) extending in a radial direction between an inner surface (112) and an outer surface (110) of the web plate (36). The radial arm (114), the inner surface (112), and the outer surface (110) are disposed about an axial passage (82) configured to facilitate a flow of combustion products (61) from the transition piece (32) to the turbine nozzle (34). The transition piece (32) is disposed within a compressor discharge cavity (28) configured to receive an oxidant (60). The radial arm (114) includes an upstream face (134) in fluid communication with the compressor discharge cavity (28). The radial arm (114) also includes an arm passage (172, 173, 174, 175) that extends an axial length (182) in an axial direction (72) from the upstream face (134) through at least an axial depth (180) of the radial arm (114). The arm passage (172, 173, 174, 175) is configured to receive a portion of the oxidant (60) through the upstream face (134).
