Abstract (en)
A turbine shroud cooling assembly (30) for a gas turbine system includes an inner shroud component (34) disposed within a turbine section of the gas turbine system and proximate a hot gas path (32) therein, wherein the inner shroud component (34) includes a base portion (40) in direct contact with the hot gas path (32). Also includes is a rib (70) protruding radially away from the base portion (40) and disposed proximate at least one cavity (54) configured to receive a cooling flow (38) from a cooling source, wherein the cooling flow (38) passes through a main passage (72) of the rib (70) for cooling the inner shroud component (34). A corresponding gas turbine system is also provided.
