Describe the function of the water treatment system in a boiler.

The function of the water treatment system in a boiler is critical for maintaining the overall health and longevity of the boiler operation. By treating the water used in the boiler, the system specifically aims to prevent scaling and corrosion. This is vital because the impurities and minerals found in untreated water can lead to the formation of deposits (scaling) on the boiler's heat transfer surfaces, which can significantly reduce efficiency and lead to overheating.

Corrosion, on the other hand, occurs when water interacts with the metal surfaces of the boiler, often facilitated by the presence of oxygen and other corrosive substances. These processes can weaken the structural integrity of the boiler, leading to costly repairs and potential failures.

Therefore, the water treatment system plays a proactive role in ensuring water quality by adding chemicals that inhibit these damaging processes. This contributes to improved operational efficiency and safety, making it essential for the longevity of boiler equipment.
