What is the purpose of gland condenser in steam turbine?
The gland steam condenser receives steam and noncondensable gases from the TGSS and condenses the steam. Air and non-condensable gases are evacuated from the gland steam condenser and discharged into the air vent system by exhaust fans.
What is gland steam in turbine?
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 .
How does a gland steam condenser work?
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.
What are the 3 types of steam turbine?
Steam Turbines. Three basic types of steam turbine are used to generate power as a by-product of process or exhaust steamml: condensing, pass-out condensing, and back-pressure.
What material is used in turbine glands?
carbon
To date, nobody has discovered, produced or invented a material for turbine glands that can better carbon. For this reason, carbon is widely employed in this capacity, except in one or two countries like Italy and the U.S.A. where soft packing glands arc preferred. Carbon glands arc reliable.
Why condenser is used in power plant?
In thermal power plants, the purpose of a surface condenser is to condense the exhaust steam from a steam turbine to obtain maximum efficiency, and also to convert the turbine exhaust steam into pure water (referred to as steam condensate) so that it may be reused in the steam generator or boiler as boiler feed water.
What is steam sealing?
Sealing Steam is used to help in creating vacuum. It seals the narrow gap between the rotating part and stationary part: that’s why its called sealing steam. One part goes inside and outside part is sucked by gland condenser.
What is dummy piston in steam turbine?
Answer: Reaction turbines have axial thrust because pressure on the entering side is greater than pressure on the leaving side of each stage. To counteract this force, steam is admitted to a dummy (balance) piston chamber at the low-pressure end of the rotor.
In which turbine condenser is not used?
Explanation: The condenser is not used in a gas turbine power plant. The essential component of a gas turbine is the compressor, combustion chamber and the turbine.
