Q

When operating with the auxiliary feed line, feed water flow is controlled __________.

🔍 Key Concepts

• Relationship between the main feedwater system and the auxiliary feed line • Difference between manual and automatic control of feedwater flow • Purpose and normal function of a feedwater regulator vs. a stop‑check valve

💭 Think About

• Ask yourself: When the auxiliary feed line is in use, is the system normally bypassing or using the main automatic control device? • Think about which component is designed to regulate flow in response to boiler conditions, and which component is primarily a shutoff/isolating or throttling valve. • Consider whether an economizer (eco) and its bypass typically controls feedwater flow or simply routes it.

✅ Before You Answer

• Identify which option actually describes a true automatic control device for feedwater flow. • Verify which component in the options is normally associated with the main feed line, not the auxiliary line. • Confirm from your steam plant diagrams whether the auxiliary feed line is intended for emergency/backup use and how operators are trained to control its flow.
