The purpose of the gland steam system is to reduce steam leakage to a minimum and to prevent air ingress.
Steam leakage leads to the requirement for increased make up; this increases the load on the feed and boiler water treatment chemicals and to a deterioration of the working environment surrounding the power plant.
Air ingress leads to a loss of vacuum and hence reduction in plant efficiency , and causes problems of thermal stressing around the gland as well as increases oxygen content of the exhaust steam.
To avoid ingress of air to the LP casing and to aprevent steam leak at the HP and IP casings.
What else can I help you with?
What is the function of gland steam in steam turbines?
Gland steam is steam supplied to the labyrinth glands of the low pressure turbine to prevent air entering in the exhaust side, which disturbs the vacuum (± 50 mbar absolute) in the condenser. Gland steam pressure is to supply at about 0,2 bar.
Is jacking oil required when stopping steam turbines?
jacking oil is not required when stopping the steam turbine
What is work of gland steam cooler in steam power plant?
gland steam cooler is used to cool steam of gland sealing comes from turbine
What are the capacity of Steam Turbines?
The capacity of each steam turbines has more than 530 GW in over 6000 installed units. The steam turbines provide high reliability and sustained high efficiency.
What is the methods of compounding of steam turbines?
no
What type of combustion engine would you classify steam turbines used in power plants?
Steam turbines are external combustion engines.
Why is excessive moisture in steam undesirable in steam turbines?
moisture present in steam due to quality of steam.
What is the Function of gland box in steam turbine?
Gland is used for the prevent leakage of oil from the gland box which is made up of copper or brass and gland box function is to support the glands which are made up of cast iron.This is called oil gland. steam gland is used for prevent the leakage of steam which exhausts air and which helps build up the vaccum in condenser is called steam gland.
