🔍 Key Concepts

• Function of a main condenser in a steam plant and what happens to non‑condensable gases (air) • Purpose of an air ejector / air removal system and where its discharge normally goes • Difference between condensers (for steam) and tanks/drains/breakers (for protection or collection)

💭 Think About

• Which component in the list is specifically designed to handle a mixture of air and a small amount of steam before it is finally released? • Which choice sounds like it is mainly for protecting vacuum rather than for continuously discharging removed air? • Think about where you would want to recover condensate versus where you would safely release non‑condensable gases to the atmosphere.

✅ Before You Answer

• Identify which option is associated with the air ejector discharge path on a typical marine steam plant diagram • Confirm which device’s primary job is not to collect water or condensate, but to deal with non‑condensable gases • Eliminate any option whose main purpose is vacuum protection or drain collection, not air venting
