What is the minimum pressure at which a bottom blow down shall be performed?

• A. 50 PSI
• B. 75 PSI
• C. 100 PSI
• D. 125 PSI

Answer: (C)

The minimum pressure at which a bottom blowdown should be performed is 100 PSI. This practice is important for maintaining boiler efficiency and safety. Performing a bottom blowdown at this pressure ensures that the sediment and impurities that accumulate in the lower section of the boiler are effectively removed. When the pressure is at or above 100 PSI, the water and steam are able to carry away these contaminants more efficiently. Below this pressure, there may not be enough force to clear out sediments effectively, which could lead to issues such as reduced heat transfer and potential damage to the boiler system. By adhering to this minimum pressure requirement, operators can ensure proper maintenance and longevity of the boiler while adhering to recommended safety standards.
