gland steam cooler is used to cool steam of gland sealing comes from turbine
A gland condenser on a steam turbine is a component designed to manage the exhaust steam and maintain a vacuum in the turbine's sealing system. It collects steam that leaks from the turbine's gland seals, condensing it back into water to reduce steam loss and improve overall efficiency. By maintaining a vacuum, the gland condenser helps optimize turbine performance and prevents air ingress, which can reduce efficiency and increase operational issues.
gland steam temp should be nearer to less than turbine lub. oil flash point.
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.
Gland staem condenser is meant for condensing the steam whichwas used for sealing the LABYRINTH GLAND and reusing it d cycle. It is then passed through d drain cooler and LP heaters and so on......
Increase the gland steam pressure if air is leaking in. If gland steam is leaking out, replace the seals. If the leak is in the casing, repair or replace the damaged parts.
gland condenser is a type of condenser in which steam which is coming from d turbine is used for the heating of demineralised water and then this water is sent to the boiler so boiling of hot water consumes less coal and thus we get benifit of it
my LP turbine differential expansion increase ,when rated gland steam temperature maintain.
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.
what are the types of interlock in steam turbine
impulsive turbine reaction turbine
Gland steam always send from bottom because if we send the gland steam from top then it has a tendency to pass directly to the bottom (condenser) .Due to this reason gland steam is send from bottom so that it occupies total turbine inside vacuum space and seal it.
