🔍 Key Concepts

• Pressure-closed feed system operation and purpose • Flow path of condensate from condenser → condensate pump → deaerating feed tank → boiler • Where vacuum exists vs. where positive pressure exists in a steam plant feed system

💭 Think About

• Trace the entire condensate/feedwater path and think about where the system is open to condenser vacuum and where it is connected to pumps or tanks under pressure. • Ask yourself: in a pressure-closed system, what happens to the pressure in the lines leading to and from the deaerating feed tank and boiler? • Consider which sections must be at a higher pressure than the condenser to avoid air leakage and maintain feed system integrity.

✅ Before You Answer

• Identify exactly where the vacuum from the condenser is present in the piping run. • Determine which component (pump or tank) first raises the pressure from vacuum to positive pressure. • Confirm which piping sections are always on the pressurized side of the condensate/feed pumps during normal operation.
