Abstract
A coolable stator assembly formed of wall segments 36 for bounding a working medium flow path 14 is disclosed. The wall segments extend circumferentially about the working medium flow path and are circumferentially spaced leaving a clearance gap G therebetween. A duct 148 for cooling air is formed by the facing sides 144, 146 of the wall segments and a pair of radially spaced seal elements such as an inner seal plate 134 and an outer air seal plate 136. In one embodiment, a primary flow path for cooling air extends radially outwardly of the wall segments and the working medium flow path extends radially inwardly of the wall segments. The duct is pressurized with cooling air from an adjacent location at an intermediate pressure between the primary flow path 32 and the working medium flow path 14.
