🔍 Key Concepts

• Function of a DC heater (dearating condenser/deaerating heater) in the feedwater system • How condensate flow rate into the DC heater affects level, pressure, and deaeration action • Relationship between auxiliary exhaust and the DC heater during normal steaming

💭 Think About

• If you suddenly add a large amount of relatively cool condensate into the DC heater, what happens to the steam inside it and to the pressure of that steam source feeding the heater? • Does rapid condensate discharge tend to improve or upset deaeration (removal of dissolved gases) in the short term? Think about contact time and temperature. • Which component listed in the choices is most directly connected to the DC heater under normal steaming conditions?

✅ Before You Answer

• Identify which choices relate to auxiliary exhaust pressure and which do not, then ask which is most immediately influenced by DC heater loading. • Recall that effective deaeration generally requires high temperature and sufficient residence time; decide whether a rapid slug of condensate would help or hinder that. • Consider whether a change in DC heater operating conditions would more likely affect a downstream heat‑transfer surface (like the economizer) or the pressure of the steam source feeding the heater.
