What is a gland steam condenser?
Gland Steam Condenser captures the leaked steam and air mixture. Once collected, the steam is separated from the air and condensed water in a shell and tube condenser. The condensate drains out of the bottom while the air is pulled out of the top.
How the gland seal steam helped the gland packing in preventing air from entering into the turbine casing?
To prevent air from entering into the turbine 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.
What is a gland seal?
A gland is a general type of stuffing box, used to seal a rotating or reciprocating shaft against a fluid. The gland nut allows the packing material to be compressed to form a watertight seal and prevent water leaking up the shaft when the tap is turned on.
Why are glands so important?
Glands are important organs located throughout the body. They produce and release substances that perform certain functions. Though you have many glands throughout your body, they fall into two types: endocrine and exocrine.
What is the role of glands?
Glands produce and release different hormones that target specific things in the body. You have glands all over your body, including in your neck, brain and reproductive organs.
How does gland steam work?
gland steam providing a seal between turbine shaft and turbine casing . so gland steam protect the leakage of steam outside of the turbine and also and suck the ambient air inside . In a turbine, rotor rotates inside the casing. these labyrinth seals causes pressure drop along the rotor .
What is the purpose of a gland steam condenser?
The function of gland steam condenser is to maintain a sub atmospheric pressure at the outmost leak off belt of the glands and thereby prevent leakage of steam to atmosphere. The sub-atmospheric pressure draws air into glands where it mixes with leaking steam from cylinder.
What is steam seal?
Due to the radiation consideration. Self-sealing means that there is a sufficient supply of steam coming from leakoff and extraction steam lines into the steam seal system. however. which transmits kinetic energy to the generator. The steam seal system is connected to the steam seals on the feedwater pump turbines.
What is a gland condenser?
The gland condenser uses cooling water to condense this steam to water which is usually lost to sewer. A steam powered eductor draws a vacuum and expels the non-condensables that are drawn down with the steam to the gland condenser. Any literature on large condensing steam turbines should include information about the gland steam condenser system.
