How does the Dump Valve function in the condensate system?

• A. To discharge excess condensate back to the reserve feedwater tank
• B. To vent air from lines
• C. To inject steam into the condensate
• D. To regulate condensate temperature

Answer: (A)

In the condensate system, the dump valve’s job is to return excess condensate back to the reserve feedwater tank. After steam is condensed, the hot condensate is collected and normally sent to the boiler feedwater system. But when the feedwater system isn’t ready to accept more condensate (or when there’s more condensate than the system can handle at that moment), the dump valve opens and sends that excess water back to the reserve feedwater tank. This prevents flooding of the condensate lines, helps maintain proper levels, and reduces the need for fresh makeup water. Venting air or injecting steam isn’t the function of this valve, and regulating condensate temperature is handled by other parts of the system rather than the dump valve.
