Q

Discharging an excessive amount of make-up feed water into the DC heater during normal steaming conditions could cause __________.

🔍 Key Concepts

• Function of the DC heater (de-aerating feed heater) in a steam plant and what "make‑up feed" is • How water level and pressure conditions in the DC heater affect downstream equipment like feed pumps and economizer • Normal steam/water flow path from DC heater → feed pumps → economizer → boiler

💭 Think About

• If you add too much make‑up water to the DC heater, what happens to the water level and how might that affect the pumps taking suction from it? • Which of the listed effects would be a more direct and immediate consequence of conditions inside the DC heater itself, rather than a secondary effect somewhere else in the system? • Think about where water hammer usually occurs and what kind of rapid changes (pressure, phase, or flow) cause it—does slow, continuous excess make‑up water fit that pattern?

✅ Before You Answer

• Identify which component(s) take suction directly from the DC heater and would be most sensitive to abnormal level conditions there. • Consider which options involve locations farther downstream (economizer, air ejector) and whether an excessive DC heater make‑up flow would reasonably be the first cause there. • Verify which effect would result from flooding or unstable level in the DC heater under normal steady steaming, not from a sudden valve operation or isolation.
