摘要

A structure of one or more improved nozzle vanes of an improved nozzle ring of a steam turbine is disclosed. In an aspect of the present invention, each of the one or more nozzle vanes includes an effective surface of the improved nozzle vane, at least one grove and a bolting surface in the improved nozzle vane. The bolting surface in each of the one or more improved nozzle vane is used for connecting the improved nozzle ring with at least one section of the steam turbine.
