Condenser Air Removal / SJAE theory Flashcards
What order do you valve out SJAE.
Air.
Steam.
Condensate.
Where do the inner condenser drains go to?
C drip receiver.
Atmospheric drain seal reservoir.
Where does the after condenser drains go to?
Turbine room sump.
Heater drain pump sump.
Miscellaneous drain tank.
What is the function of the air ejectors.
Remove air and non condensable gasses from the main and feed pump condensers.
What is the steam source for the steam jet air ejectors?
125# Aux steam header.
What will the startup air ejectors draw down to?
15hg
What will the holding air ejectors draw down to?
28hg
What happens when you valve in the local air flow manometers on U1 air ejectors?
You bypass the rad monitor.
What is the purpose of condensate flow differential pressure indicator CDI-200?
Provides indication of differential pressure across the SJAE condenser. 0 – 20 feet H2O ∆P High alarm at 15 feet H2O (2800 GPM) Low alarm at 2 feet H2O (1200 GPM).
What order do you valve in SJAE.
Condensate.
Steam.
Air.
