How often should boilers perform blow down?

Performing boiler blowdown a couple of times a day is important for maintaining optimal boiler operation. Blowdown is the process of removing a portion of the water from the boiler to eliminate accumulating solids, such as minerals and contaminants, that can concentrate over time. If these solids are not periodically removed, they can lead to problems, including reduced efficiency, overheating, and even mechanical damage.

Blowing down multiple times each day helps to manage these concentrations effectively, ensuring that the boiler operates at peak performance and extends its lifespan. The specific frequency can depend on various factors, including the type of boiler, its capacity, and the quality of the feedwater. However, performing blowdown just once a week, once a day, or only during maintenance would not sufficiently address the buildup of total dissolved solids, which could lead to operational issues. Therefore, a couple of times a day strikes a good balance for regular maintenance and performance optimization.
