🔍 Key Concepts

• Steam plant drain systems and what they handle (steam vs water, clean vs dirty) • Difference between high pressure and low pressure drains in a marine boiler/steam plant • Which systems deal with contaminated vs uncontaminated drains

💭 Think About

• Ask yourself: high and low pressure drains from steam equipment and heaters are usually grouped under what general plant system? • Which option best fits drains that might come from multiple pieces of high‑pressure and low‑pressure steam equipment? • Which choice clearly refers to a system specifically designed to deal with various pressure levels of steam/water drains throughout the plant?

✅ Before You Answer

• Check which listed system would logically include drains from multiple pressure ranges in the steam cycle • Verify which option is typically associated with handling plant-wide steam/water drains (not just one component like an auxiliary turbine) • Eliminate any option that obviously deals only with one specific source of drains instead of the whole steam system
