Where are D.A. tanks typically located in relation to the feedwater pump?

D.A. tanks, or Deaerating Feedwater Tanks, are critical components in steam generation systems. They are designed to remove dissolved gases, primarily oxygen and carbon dioxide, from the feedwater before it enters the boiler. This process helps to prevent corrosion and increases the efficiency of the steam system.

When it comes to their placement, D.A. tanks are typically positioned above the feedwater pump in the system. This arrangement leverages gravity to facilitate the flow of water. By having the D.A. tank located above, the weight of the water helps create the necessary head pressure for the feedwater pump to operate effectively. This ensures a consistent and reliable supply of feedwater to the boiler.

Understanding this positioning is vital for maintaining the operational efficiency and longevity of the steam generation system, since improper placement can lead to issues such as pump cavitation or reduced feedwater flow rates.
