9. Auxiliary training - Seal water SYSTEM

As the turbine is tripped, air is let into the condenser through vacuum breaker valve to increase the condenser pressure and as a result to make a brake for the rotor to stop more quickly.

1. Auxiliary Systems:
Control Air System
Condensation System
Hydromotor
Lube Oil System
Drainage System
Seal Steam/Leak-off/Gland Steam Condenser
Control Oil System
Seal Water System
Bypass System
Steam Turbine E30-16-1*6.3

2. The outline of the system:
As the turbine is tripped, air is let into the condenser
through vacuum breaker valve to increase the condenser
pressure and as a result to make a brake for the rotor to
stop more quickly.
While the system is working, no air should enter the
turbine/condenser space, therefore the vacuum breaker
valve is sealed by a small constant mass flow of water of
about 3.8 kg/s.
