🔍 Key Concepts

• Function of a deaerating feed water tank (direct-contact heater) in a steam plant • How makeup water and condensate returns are controlled during maneuvering when steam flow and exhaust conditions change rapidly • The effect of valve misoperation vs. normal recirculation/dumping on the level inside the DFT

💭 Think About

• Think about which option would most directly add water into the deaerating feed water tank faster than it can be used during maneuvering, rather than sending water away from the tank. • Ask yourself: during rapid engine load or speed changes, which valve or line is most likely to cause a sudden surge of additional makeup water or condensate into the tank if not controlled properly? • For each choice, decide: does this action tend to remove water from the DFT, keep it about the same, or add extra water beyond normal control limits?

✅ Before You Answer

• For each option, trace the direction of flow: Is feedwater/condensate going into the deaerating tank or away from it? • Identify which item would bypass normal level control and allow extra water to enter the tank without being regulated by the automatic level controller. • Consider maneuvering conditions: changing auxiliary exhaust and live steam availability. Which line is designed to supplement the system and could overfill the heater if misoperated?
