What is the corrective measure when water hardness affects boiler operation?

When water hardness affects boiler operation, one of the most effective corrective measures is the implementation of blow-off procedures. This practice helps to manage the buildup of scale and sediments created by hard water, which can accumulate on boiler surfaces over time.

Blow-off procedures involve periodically removing water and sediment from the boiler to ensure that impurities do not concentrate and lead to overheating or structural damage. By expelling a portion of the water, the concentration of hardness minerals is reduced, allowing for better heat transfer and preventing operational issues related to scale buildup. This method is essential for maintaining the efficiency and longevity of the boiler system.

Regular cleaning, pressure testing, and temperature adjustments, while important for overall maintenance and operational integrity, do not specifically address the issue of water hardness in the same direct manner as blow-off procedures. Regular cleaning may help manage some scale but does not actively reduce the effects of hard water on its own. Pressure testing is useful for ensuring the integrity of the boiler, and temperature adjustments can optimize performance, but these measures do not correct the foundational issue of water hardness itself.
