What is often the result of improper water treatment in a boiler?

Improper water treatment in a boiler often leads to corrosion and scaling, making it the correct answer. When water is not treated properly, it can contain impurities such as minerals and dissolved gases. These impurities contribute to the formation of scale on heat transfer surfaces, which reduces thermal conductivity and efficiency. This buildup not only hinders the performance of the boiler, leading to increased energy consumption, but can also cause overheating and potential failure of components due to restricted water flow.

Additionally, improper treatment may lead to corrosion, primarily because of the presence of oxygen and other corrosive agents in the water. Corrosion can deteriorate metal surfaces, resulting in leaks and structural weaknesses that could have serious operational consequences. Thus, adequate water treatment is essential to prevent these issues, ensuring the longevity and efficient operation of the boiler system.
