FIELD: power industry.
SUBSTANCE: turbine includes first internal wall, second internal wall, internal lining and protective element. First internal wall and second internal wall are mounted on internal lining. First and second internal walls are positioned so as the internal space through which turbine work fluid can flow is separated from external space through which cooling fluid can flow. First and second internal walls and internal lining are positioned against each other so as a cavity is formed in the external space. Protection element is positioned inside the cavity so that the protective element separates the cavity into internal zone and external zone formed in radial external position against the internal zone.
EFFECT: efficient cooling of turbine parts.
