The abbreviation DFT stands for which component?

• A. Deaerating Feed Tank (DFT)
• B. Direct Feed Tank
• C. Deaerator Vessel
• D. Drainage Filter Tank

Answer: (A)

DFT stands for Deaerating Feed Tank. This component acts as a reservoir for boiler feedwater and includes a deaeration function to remove dissolved gases, mainly oxygen and carbon dioxide, before the water is sent to the boiler. Steam is used to heat the water and vent the released gases, reducing corrosion risk and helping maintain a steady, clean feed to the boiler even as load changes. A direct feed tank would not deaerate the water; a deaerator vessel is a separate unit focused solely on deaeration, and a drainage filter tank serves an unrelated purpose.
