🔍 Key Concepts

• Function and normal operating pressure of high-pressure steam drains in a propulsion plant • Purpose of a DC heater, reserve feed tank, and drain/inspection/atmospheric drain systems • Where it is safest to discharge high-energy condensate/flash steam

💭 Think About

• Think about what happens to high-pressure steam when it is drained and suddenly exposed to lower pressure—what does that do inside a closed tank? • Which of these locations is specifically designed to handle flashing condensate and vent it safely without over‑pressurizing anything? • Which option would you least want to shock with sudden high-pressure drains because it is critical to feedwater quality and suction to the feed pumps?

✅ Before You Answer

• Verify which system is designed to be vented to atmosphere and handle flashing condensate safely • Check which tanks are part of the main feedwater circuit and therefore normally kept under controlled conditions, not used as dumping grounds for high‑pressure drains • Confirm which choice is commonly associated with collection and observation of various drains from the steam system
