Minimizing Leakage in Steam Turbine Condensers
Oftentimes during start up and low-load conditions, the steam turbine’s condensation from the inlet high-pressure (H.P.) end will leak from the outboard gland. And the low-pressure (L.P.) end of the turbine will be under the vacuum of the condenser.
This vacuum may pull in cold atmospheric air through the seals along the shaft. Cold air could be detrimental to the hot metal of the shaft, posing the risk of equipment damage.
