🔍 Key Concepts

• Dissolved oxygen removal processes in a steam plant (condenser and deaerating feed heater roles) • How makeup feed differs from normal condensate return in terms of oxygen content • The effect of boiler priming and auxiliary exhaust dumping on what is carried over from the condenser

💭 Think About

• For each choice, ask: does this condition guarantee that oxygen from the condenser ends up in the feed system, or could it occur without increasing oxygen carryover? • Think about which component actually removes oxygen and what happens when you introduce water or steam that has not gone through that removal process. • Separate conditions that affect purity of steam (like priming) from those that affect the oxygen content of the condensate itself.

✅ Before You Answer

• Identify which option involves introducing relatively untreated water into the cycle instead of closed-loop condensate. • Confirm which equipment (condenser, DC heater, etc.) is designed to strip dissolved gases, and whether the option would bypass or overload that function. • Eliminate any choice where oxygen carryover would only be possible under certain malfunctions, not "always" when that condition exists.
