Dissolved oxygen in the condensate is generally attributed to _________.

Question 1 of 27070

Dissolved oxygen in the condensate is generally attributed to _________.

🔍 Key Concepts

• Condensate system and where it can pick up dissolved gases • How makeup feedwater is treated to remove oxygen • Which problems (leaks, exhausters, pumps) change pressure/flow vs which actually introduce fresh water with oxygen

💭 Think About

• Which option actually introduces new water that has had contact with the atmosphere and can carry dissolved oxygen into the system? • For the other options, think: do they mainly affect system efficiency/pressure, or do they provide a direct source of air-saturated water? • In a closed steam–condensate cycle, where is the main point that outside (untreated or less-treated) water can enter?

✅ Before You Answer

• Identify which choice is the only direct source of water that may contain atmospheric oxygen • Recall how deaeration (oxygen removal) is normally applied to feed/makeup water • Eliminate options that relate mainly to mechanical faults (leaks, vapor lock, exhauster issues) without actually adding new water from outside the system
