ABSTRACT:
A stator heat shield (6) for a gas turbine (1) includes an outside (11) which in the installed state faces a hot gas path (9) of the gas turbine (1), and an inside (12) facing away from the outside (11). A plurality of ribs (13) are formed on the inside (12) and extend axially in the installed state with regard to an axis of rotation (8) of a rotor (3) of the gas turbine (1) and, in the circumferential direction, are spaced a distance apart from one another. At least one baffle plate (14) is arranged on the inside (12) and is in contact with the ribs (13). At least one groove (16) is designed in an end face (15) bordering the stator heat shield (6) in the circumferential direction, into which at least one sealing element (18) can be inserted. A plurality of bores (19) are included, each opening at a distance from the groove (16) in the direction of the outside (11) at the inside (12) at one end and on the end face (15) at the other end and arranged a distance apart from one another in the axial direction.
