Operating Experience With Improved Steam Turbine Packing Rings.
Abstract
The losses in turbine performance due to excessive leakages in the labyrinth seals can result in significant heat rate degradation to the turbine cycle. The modified packing arrangement described helps eliminate the rubs that occur during startups, which is the major cause of excessive clearance. This packing was first installed at two utility generating stations. The performance of these units were monitored to evaluate the packing and these results are discussed in detail.
