Abstract (en)
A system for cooling a hot gas path component for a combustor generally includes an impingement sleeve 74 that circumferentially surrounds an outer surface of the hot gas path component. A first cooling chamber is defined between the impingement sleeve 74 and a first portion of the outer surface 82 of the hot gas path component. A second cooling chamber is disposed downstream from the first cooling chamber. The second cooling chamber is defined between the impingement sleeve 74 and a second portion of the outer surface 90 of hot gas path component. An inlet 96 extends through the impingement sleeve 75 so as to define a first flow path into the first cooling chamber. An outlet 104 defines a second flow path between the first cooling chamber and the second cooling chamber. Corresponding gas turbine combustor and cooling method are also provided.
