The HP Steam Drain System returns condensate suitable for use as boiler feedwater back into the system via which component?

The HP Steam Drain System returns condensate suitable for use as boiler feedwater back into the system via which component?

• A. Deaerating Feed Tank (DFT)
• B. Main Condenser
• C. Fresh Water Tank
• D. Boiler Drum

Answer: (A)

The condensate from the HP steam drain is returned to a place where it can be deaerated and heated before re-entering the boiler feedwater system. That role is filled by the Deaerating Feed Tank. In the DFT, dissolved gases like oxygen and carbon dioxide are removed and the condensate is warmed, making it suitable as boiler feedwater. From the DFT, feedwater is then pumped back to the boiler through the standard feedwater system, which helps conserve makeup water and reduce corrosion risks. The main condenser simply condenses exhaust steam and isn’t used as the feedwater reservoir, the Fresh Water Tank holds makeup water, and the boiler drum is part of the boiler itself, not the condensate return/deaeration stage.
