What does boiler blowdown refer to?

• A. The process of adding water to a boiler for cooling purposes
• B. The removal of a portion of water from a boiler to control the concentration of impurities
• C. A method of cleaning boilers
• D. The process of filling up a boiler

Answer: (B)

Boiler blowdown refers to the removal of a portion of water from a boiler to control the concentration of impurities. Over time, water in a boiler can become concentrated with minerals and other contaminants, which can lead to issues such as scaling and corrosion within the boiler system. By performing blowdown, operators can ensure that these impurities do not reach detrimental levels, thereby maintaining the efficiency and longevity of the boiler. This process is essential for safety and operational effectiveness, allowing for better heat transfer and preventing potential failures or reduced performance due to buildup. The other options involve different processes that do not accurately describe the function and purpose of blowdown, such as adding water for cooling or filling up a boiler, which do not address the need to manage water quality within the system.
