Gland Seals Stationary and rotating turbine components must be sealed to prevent steam leakages into the atmosphere, air leakages into the LP turbine, maintain the correct and efficient steam flow within the turbine. Since contact-type shaft sealing can cause distortion and deformation of the rotor, sealing segments are designed to be non-contacting during operation thus limiting friction casing, sealing steam is led to the turbine glands. The sealing steam first passes through the throttle steam valve and then the safety orifice in order to reduce its pressure to 0.01~0.08MPaG before reaching the turbine glands. During operation of the turbine, the LO is supplied to the bearing metal, reduction gear, and other components through the main LO pump. Besides, in order to maintain

The gland becomes self-sealing once the internal steam pressure is sufficiently high. Initially there is no internal steam pressure and the external gland steam supply is required to prevent air ingress at the glands and thus allow condenser vacuum to be established prior to rolling the unit.

Conventional gland sealing in general purpose steam turbines is accomplished with carbon rings. A carbon ring comprises three segments held together with a garter spring. Typically, the steam end and exhaust end gland boxes each carry four to five carbon rings, though there may be more. Unlike labyrinth seals, carbon rings are not rigidly mounted into a turbine’s casing; the segments are Large gas and steam turbine applications commonly employ brush seals to reduce the leakage gap experienced with labyrinth seals – increasing operational effi ciencies. In general purpose steam turbines, brush seals enhance the performance and longevity of carbon rings.
