What is the main purpose of a blowdown in boiler operation?

• A. To increase pressure
• B. To control steam output
• C. To maintain safe water levels and remove impurities
• D. To enhance heat transfer

Answer: (C)

The main purpose of a blowdown in boiler operation is to maintain safe water levels and remove impurities. Over time, dissolved solids and impurities accumulate in the boiler water, which can lead to scaling, corrosion, and reduced efficiency. By performing blowdown, a portion of the concentrated boiler water is removed, thus maintaining the water quality within safe operational limits. This practice ensures that the system remains efficient and minimizes the risk of equipment damage. Maintaining the right water quality is essential for the safe and effective operation of the boiler.
