12 ABSTRACT OF THE DISCLOSURE The combustion turbine compressor diaphragm is provided with improved diaphragm box seal. A channel- shaped seal support structure is affixed to the inner surface of the inner shroud. The base of the seal support structure defines a plurality of grooves for receiving seal strips which may be rolled into position and mechan- ically locked, such as by peening. Because the thickness of the seal support base may be increased over that of the inner shroud, the box seal increases the flexibility of seal design. In addition, the box seal improves the structural rigidity of the inner shroud.
