🔍 Key Concepts

• purpose of the automatic recirculating valve in a main condensate system • how temperature at different points in the condensate line reflects condenser/air ejector performance • relationship between condensate temperature and protection of the main condensate pump

💭 Think About

• At what point in the system would temperature be most critical to protect the main condensate pump from overheating or loss of suction? • Which location’s temperature would change first if the condensate flow to the condenser or air ejectors became too low? • Think about where you would want to sense temperature so the recirculating valve can respond quickly and maintain stable operation.

✅ Before You Answer

• Identify which of the four locations is directly related to the main condensate pump’s operating conditions. • Consider where abnormally high condensate temperature would be most harmful to system reliability. • Verify which location would give the most representative temperature of what the pump is actually receiving.
