What is a common symptom of water treatment issues in boilers?

A common symptom of water treatment issues in boilers is corrosion and scaling. When the water used in the boiler system is not treated properly, impurities such as minerals, oxygen, and other contaminants can lead to the formation of rust and scale.

Corrosion occurs when the metal components of the boiler react with water and oxygen, leading to deterioration of the materials. Scaling happens when minerals precipitate out of the water and accumulate on the heating surfaces, insulating them and reducing heat transfer efficiency. Both of these issues can significantly impact the performance and longevity of the boiler, resulting in decreased efficiency, increased maintenance costs, and potential failure of the system.

In contrast, increased efficiency, stable steam output, and lower operating temperatures would not be expected outcomes of untreated water in a boiler system. These conditions reflect a well-maintained and properly treated system rather than the negative effects seen with water treatment issues. Thus, corrosion and scaling serve as clear indicators of the necessity for proper water treatment and management in boiler operations.
