Question 1 of 27070

During normal operation, the steam flow from the auxiliary exhaust line to the DC heater can be closely related to the _______.

🔍 Key Concepts

• Function of a DC (de-aerating) heater in a steam plant • How auxiliary exhaust steam is used for heating and deaeration • What controls the amount of steam admitted to the DC heater under normal conditions

💭 Think About

• Ask yourself: in steady, normal operation, what DC heater condition would logically require more or less auxiliary exhaust steam? • Which variable in the answer choices would directly change the steam admission, rather than being more of an internal result of heating? • Think about what the DC heater is trying to maintain constant (e.g., certain temperature/condition of feedwater) and which choice ties to that goal most closely.

✅ Before You Answer

• Identify which choice is most directly tied to heat transfer demand in the DC heater, not just a secondary effect. • Consider which parameter the control system or operator would actually sense to regulate auxiliary exhaust steam flow. • Eliminate any options that are more likely dependent outcomes of steam flow, rather than the controlling/related cause of that flow.
