Does condensate return need to go through a flash tank prior to a DA tank for a steam boiler system?

In a steam boiler system, condensate return does not necessarily need to go through a flash tank before entering the Deaerator (DA) tank. However, using a flash tank can be beneficial in recovering some heat and reducing pressure, allowing for more efficient use of the condensate. This process can help minimize the amount of makeup water required and improve overall system efficiency. Ultimately, whether to include a flash tank depends on the specific system design and operational requirements.
