Abstract
A shroud support includes an annular casing and an annular hanger spaced radially inwardly therefrom. The hanger includes a circumferentially extending flow duct therein and a base for radially supporting a shroud positionable radially over a plurality of circumferentially spaced turbine blades. The hanger is cooled by channeling a cooling fluid circumferentially inside the hanger flow duct for providing more uniform circumferential blade tip clearance and for better matching the thermal movement between the shroud and blade tips.
