🔍 Key Concepts

• Function of a deaerating (DC) heater in removing dissolved oxygen from feedwater • Importance of proper venting to remove non-condensable gases like oxygen • Effects of water level and makeup feed rate on deaeration efficiency

💭 Think About

• For each option, ask: would this condition make it harder or easier for oxygen to be released and vented from the feedwater? • Think about what happens to oxygen and other gases if the vent is not working properly. • Consider whether more cold makeup water automatically means more oxygen in the boiler, or if the deaerating heater should handle it when operated correctly.

✅ Before You Answer

• Review how a deaerating heater actually removes dissolved gases (pressure, temperature, and venting). • Identify which listed condition(s) would directly interfere with oxygen leaving the water and escaping to atmosphere. • Check if any of the options describe a situation that might affect performance, but would still allow effective deaeration if the heater is operating correctly.
