WebThis sealing steam from the low-pressure end and the normal leakage from the high-pressure end would tend to leak out and blow towards the bearing housing. To reduce the chance of this leakage causing an accumulation of water in the lube oil system, we use a gland steam condenser to draw a very small vacuum (typically 2 or 3 in-Hg) within the ... WebDec 3, 2015 · The steam turbine gland steam seal system is designed to keep steam from leaking out of the turbine and to prevent air from leaking into the turbine. A gland seal system can be as simple as a spray chamber, loop seal and a steam ejector or as complex as surface condensers, air blowers or vacuum pumps.
