ABSTRACT:
A vacuum retaining arrangement for retaining a vacuum within a condenser of a steam power plant during a short term outage or shutdown. At least a portion of a turbine gland packing near the condenser, with respect to a sealing steam supply portion, is connected and communicated with an air extractor through a gland condenser. The sealing steam which would otherwise flow into the condenser from the turbine gland package is suctioned or extracted from the gland packing into the gland condenser and the air extractor during the short term outage or shutdown so as to prevent the sealing steam from leaking into the condenser.
