Which tank is associated with maintaining water quantity when condensate and MUF are present?

• A. Deaerating Feed Tank (DFT)
• B. Surge Drum
• C. Condensate Storage
• D. Hotwell

Answer: (A)

The tank that handles maintaining the water quantity when condensate returns and makeup water (MUF) is involved is the Deaerating Feed Tank. It acts as a reservoir that collects condensate from the condensate system and blends it with MUF, providing a steady supply of feedwater. It also deaerates the water before it is pumped to the boiler, helping maintain a consistent boiler feed and protecting against corrosion. The other tanks play different roles: a surge drum dampens condensate/steam fluctuations, condensate storage holds condensate for later use, and the hotwell collects turbine exhaust condensate, but none of them are specifically designed to combine condensate with MUF to sustain boiler feedwater quantity.
