What is the purpose of a blowdown tank?

• A. To collect water blown down from the boiler
• B. To store feedwater
• C. To measure system pressure
• D. To regulate steam flow

Answer: (A)

The purpose of a blowdown tank is to collect water that has been blown down from the boiler. In boiler operations, it is essential to remove impurities and concentration of solids from the boiler water to maintain efficiency and prevent damage to the system. This process is known as blowdown, where a portion of the water is intentionally removed to lower the concentration of dissolved solids. The blowdown tank serves as a storage vessel for this discharged water, allowing it to cool and separate from any contaminants before it is properly disposed of or treated. This helps in maintaining safe operating conditions and prolonging the life of the boiler system.
