ABSTRACT:
An arrangement for a dry-gas sliding ring seal in a turbomachine which establishes ambient conditions in the region of the dry-gas sliding ring seals under which no fluid precipitates regardless of whether the machine is operating or not. By supplying heat to the leakage flow during standstill of the turbomachine in a manner similar to that during its operation, an undercooling in the region of the dry-gas sliding ring seal with all its negative effects can be suppressed; and the start-up of the turbomachine takes place starting from a substantially safer operating state.
