What is the key benefit of using a boiler water softening agent?

• A. Enhances ignition
• B. Reduces scale formation
• C. Increases water pressure
• D. Improves combustion efficiency

Answer: (B)

Using a boiler water softening agent primarily serves to reduce scale formation in the boiler system. Hard water contains minerals such as calcium and magnesium that tend to precipitate and form scale on the boiler's internal surfaces when heated. This scale buildup can lead to several problems, including reduced thermal efficiency and overheating of boiler components, which can eventually cause equipment failure.

By softening the water, these minerals are removed or neutralized, which significantly diminishes the likelihood of scale accumulation. This results in a more efficient heat transfer process and extends the lifespan of the boiler by maintaining its operational integrity. Consequently, reducing scale formation is essential for maintaining boiler efficiency and reliability.
