What is the proper procedure for mechanically cleaning the water side of boiler tubes?

The proper procedure for mechanically cleaning the water side of boiler tubes involves using a rotating cutter head while keeping it in motion. This technique is effective because it allows for the removal of scale and deposits with precise cutting action, which is crucial for maintaining the efficiency and longevity of boiler tubes.

Using a rotating cutter head keeps the cleaning tool moving, ensuring that the cutting action is evenly applied and reducing the risk of damaging the tube material. Constant motion also helps prevent the accumulation of debris in one area, which can occur if the tool is left stationary.

This method is preferred over options like high-pressure water jets or applying heat directly, which may not provide the same level of precision and could potentially lead to tube damage or incomplete cleaning. Mechanical methods like manual scraping can be labor-intensive and less effective in thoroughly cleaning the internal surfaces of the tubes.
