Question 347Steam Plants - Assistant Engineer

The correct answer is B) DFT (Deaerating Feed Tank). The deaeration of condensate primarily occurs in the deaerating feed tank (DFT) section of the illustration SG-0010. The DFT is designed to remove dissolved gases, such as oxygen and carbon dioxide, from the condensate before it enters the boiler. This deaeration process helps prevent corrosion and other issues in the boiler system. The other options are incorrect because the main condenser hotwell, distilled water tank, and first stage feed heater are not the primary locations where deaeration of condensate occurs. The DFT is specifically designed and intended for this purpose.
