Which of the following is the advantage of operating a typical closed feedwater system for a marine boiler when compared to an open feedwater system?

🔍 Key Concepts

• Closed vs open feedwater systems and what happens to condensate in each • How oxygen and impurities get into boiler water and why they are dangerous • The relationship between system pressure, temperature, and dissolved gas removal

💭 Think About

• In a closed feedwater system, where does the condensate go after leaving the condenser, and how much contact does it have with air compared to an open system? • Which system (closed or open) is more likely to pick up extra oxygen and impurities from the atmosphere, and what does that mean for boiler corrosion risk? • Think about what you most want from a boiler feed system: lower pump pressure, less heating, less purity, or better control of dissolved gases—what would be the main safety and longevity benefit?

✅ Before You Answer

• Verify which option deals directly with oxygen control and corrosion in boilers. • Check whether a closed system is more likely to reduce or increase contact with atmospheric air (and thus oxygen). • Confirm that options about reduced purity requirements and lower pump pressures are realistic for a high‑pressure marine boiler system.
