Why is it important to condition boiler water?

Conditioning boiler water is crucial for maintaining optimal boiler performance and longevity. The primary purpose is to prevent issues such as scale formation, pitting, and carryover.

Scale development occurs when minerals precipitate out of the water and adhere to the heat exchange surfaces, insulating them and hindering efficient heat transfer. This can lead to overheating and potentially catastrophic failures. Pitting is a localized form of corrosion that can occur when there are impurities in the water or when the water chemistry is unbalanced, which can create weak points in the metal surfaces of the boiler. Carryover, the undesirable phenomenon of water droplets being entrained in the steam, can lead to water hammer in steam lines and result in ineffective steam usage.

Proper conditioning of boiler water helps to control these issues by managing the chemical composition and properties of the water, ensuring it remains free of contaminants that can lead to these problems. This proactive approach maximizes boiler efficiency, reduces downtime for maintenance, and extends the lifespan of the boiler system.
