How is water treated before entering the boiler?

Water treatment before entering a boiler is crucial to ensure efficient operation and longevity of the equipment. The correct approach involves multiple steps: filtration, softening, and chemical treatment.

Filtration is necessary to remove physical impurities such as particles, dirt, and debris that can cause clogs and damage within the boiler system. Softening addresses the hardness of the water, which is typically due to calcium and magnesium ions. This is important because hard water can lead to scaling within the boiler, reducing thermal efficiency and potentially causing overheating or even damage to boiler tubes.

Chemical treatment is another vital aspect. This may include the addition of chemicals to prevent corrosion, scale formation, and to adjust the pH of the water to optimal levels for boiler operation. This comprehensive treatment method is essential in maintaining boiler health and efficiency, and it directly impacts the performance and safety of the entire system.

Other methods such as simply letting water sit, using just a strainer, or cooling it to room temperature are insufficient. They do not adequately address the potential for scale formation, corrosion, or contamination, making them ineffective for preparing water for boiler use.
