What does "chemical dosing" entail in boiler maintenance?

Chemical dosing in boiler maintenance refers specifically to the addition of chemicals aimed at treating water quality issues. Boilers operate using water, which can be affected by various impurities such as minerals, oxygen, and contaminants that can lead to problems like corrosion, scale formation, and foaming.

By dosing the water with appropriate chemicals, operators can condition the water to help prevent these issues. For example, chemicals might be added to neutralize acids, control scale deposits, or prevent corrosion. This practice is vital for maintaining the longevity and efficiency of the boiler system, ensuring safe and effective operation.

Enhancing fuel combustion, removing sludge, or replacing old water can be relevant boiler maintenance activities, but they do not fall under the specific term "chemical dosing," which is primarily focused on water quality management.
