What system is directly piped into your boiler flash tank?

In a boiler system, the flash tank is used to separate steam from hot water or condensate. The flash tank collects water that may contain dissolved solids and provides a method for removing these impurities through a blowdown system. Continuous blowdown is the correct answer because it is specifically designed to remove a small, continuous stream of water from the boiler to control the concentration of dissolved solids in the boiler water. This process helps maintain proper water quality and reduces the risk of scaling and corrosion inside the boiler.

Continuous blowdown is usually piped directly to the flash tank, where the high-temperature liquid transitions into steam due to the reduced pressure in the tank. This steam can then be utilized in the system. The other options do not directly involve the flash tank in the same manner. For example, intermittent blowdown releases water in larger quantities at intervals, while the steam supply refers to the generated steam that is distributed for use. The feedwater supply is the water added to the boiler to replace what has been lost through evaporation and blowdown, but it is not connected directly to the flash tank in the way continuous blowdown is.
