FIELD: power engineering.
SUBSTANCE: high pressure turbine comprises an outer jacket and an end wall. The end wall includes upper and lower halves connected to each other along flanges with fastening elements, and also a sealing shell. The sealing shell is made with a circular bore, a hole for cooling medium supply into the circular bore and holes for supply of cooling gas from the circular bore to fastening elements of flanges of the end wall, which are in the space between the end wall and the inlet insert.
EFFECT: invention makes it possible to increase reliability of a gas turbine plant and to prevent thermal deformation of a high pressure turbine vessel.
