🔍 Key Concepts

• Deaerating feed heater purpose – removing dissolved gases like oxygen and carbon dioxide from feedwater to protect the boiler • Difference between condensable (steam) and non‑condensable gases in a deaerator • Role of a vent condenser – what happens to steam and what happens to non‑condensable gases at the vent

đź’­ Think About

• Think about what is actually leaving the deaerator through the vent: is it mostly steam, mostly released gases, or a mixture? • Ask yourself: if you simply vented all of that mixture to atmosphere without any extra equipment, what important loss would occur and what is the vent condenser trying to prevent? • Which of the answer choices clearly refers to the relationship between steam and the non‑condensable gases at the vent outlet, rather than just the gases themselves?

âś… Before You Answer

• Be clear on the definition of non‑condensable gases versus steam in this context • Confirm which part of the vent stream you would want to recover as condensate instead of wasting it • Eliminate choices that talk about specific equipment (like steam traps or steam glands) that are not directly part of a deaerating feed heater’s normal venting process
