various types of seals in a steam turbine. Although there are several seal designs that employ such mechanisms as disc pumping and the inclined plane in the form of screw type threads to impede the leakage of fluids, this discussion will focus on throttling type seals which are most common to steam turbines.
IMPORTANCE OF GLAND SEALING SYSTEM IN TURBINE OPERATION …
2016年11月19日 · The steam seal inside the steam turbine includes partitions and the surrounding strap seal, high pressure cylinder and low-pressure cylinder end steam seal. These steam seal effectively prevents steam leakage in each chamber, steam leak out and air leak into.

Gland sealing in general purpose steam turbines
2016年8月17日 · Large gas and steam turbine applications commonly employ brush seals to reduce the leakage gap experienced with labyrinth seals, increasing operational efficiencies. In general-purpose steam turbines, brush seals enhance carbon rings’ performance and longevity.
GE Energy has retrofitted brush seals into more than 19 operating steam turbines. Brush seals offer superior leakage control compared to labyrinth seals, owing to their compliant nature and ability to maintain very tight clearances to the rotating shaft. Seal designs have been established for steam turbines ranging in size from 12 MW
