Turbomachine and method for cooling a turbomachine

摘要

A turbomachine, especially a steam turbine, includes a casing, an inflow region formed at least in part by the casing for guiding working fluid, a feed for a cooling fluid, a rotating-blade carrier disposed in the casing and extending along a principal axis, and a shielding element disposed in the inflow region for shielding the rotating-blade carrier from the working fluid. The shielding element is attached to the casing by a mounting and the feed is guided through the mounting. A method is also provided for cooling one or more components of a turbomachine adjoining an inflow region for a hot working gas.
