The primary reason for conducting a boiler blowdown is to control the concentration of impurities in boiler water. Over time, water in the boiler evaporates to produce steam, leaving behind dissolved solids and impurities. As these impurities accumulate, they can lead to corrosion, scaling, and foaming, which can negatively impact the efficiency and safety of the boiler system.

Blowdown helps to remove a portion of the concentrated water from the boiler, thereby reducing the levels of contaminants and maintaining water quality within acceptable limits. This process is critical for the longevity and effective operation of the boiler, ensuring that it functions safely and efficiently.

While other options may seem relevant, they do not directly address the main purpose of the blowdown process. Releasing steam pressure pertains more to safety protocols rather than maintenance of water quality, adding more water to the boiler involves different processes such as feedwater management, and lowering the temperature of the boiler is not a typical objective of blowdown activities.
