Which chemical is typically used to neutralize acidity in boiler treatment?

Caustic soda, or sodium hydroxide, is commonly used to neutralize acidity in boiler treatment. When added to water, caustic soda raises the pH level, reducing the acid concentration in the boiler system. This action is important because maintaining a proper pH level helps prevent corrosion and scaling within the boiler. The presence of excess acidity can lead to significant damage to boiler components over time.

Understanding boiler water chemistry is crucial for safe and effective boiler operation. By using caustic soda, operators can ensure that the water chemistry remains within safe operating parameters, thus enhancing the longevity and efficiency of the boiler.
