<p>PROBLEM TO BE SOLVED: To propose a seal system for a gas turbine which minimizes leakage during transient and steady state operation and avoids dangerous rubbing for all operating conditions.SOLUTION: A system comprises: a second seal base 11 facing in the axial direction from a turbine stator 49, 50; a second seal 12 attached to the second seal base 11 and extending axially from the second seal base 11 towards a rotor 47, 48; 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.</p> |
