🔍 Key Concepts

• Auxiliary exhaust system purpose and typical users on a steam plant • Difference between main steam users and auxiliary/low‑pressure steam users • Which components normally require steam vs. exhaust steam for their operation

💭 Think About

• For each choice, ask: does this component usually need high‑pressure, clean main steam, or can it use lower‑pressure exhaust steam? • Think about where the auxiliary exhaust line usually discharges and what kind of services are connected to it on a steam ship. • Which of these items actually use steam directly as part of their operation, and in what form (motive steam, heating steam, or atomizing steam)?

✅ Before You Answer

• Identify which options are normally driven mechanically or by main steam turbines, rather than by auxiliary exhaust steam. • Verify which system(s) are commonly associated with heating or low‑pressure steam services rather than power‑driving services. • Eliminate any option that would logically require high‑pressure, non‑contaminated steam rather than lower‑pressure auxiliary exhaust.
