More Information
Summary:The disclosure pertains to a seal system for a passage between a turbine stator (49, 50) and a turbine rotor (47, 48), comprising: a first arm (6) extending radially outwards from the turbine rotor (47, 48) and toward the first seal (8) arranged on the stator (49, 50), and terminating short of the first seal (8) thereby creating a first gap (9) between the first seal (8) and the first arm(6). The seal system further comprises a second seal (12) arranged on the turbine stator (49, 50), and a second arm (10) extending axially from the turbine rotor (47, 48) towards the second seal base (11), and terminating short of the second seal (12) thereby creating a second gap (13) between the second seal (12) and the second arm (10). The disclosure further refers to a gas turbine comprising such a seal system.
