It's well known that scale buildup is a common and serious issue in the operation of industrial boilers. If not properly managed, it can lead to reduced efficiency, increased fuel consumption, and even equipment failure. To address this problem, I have gathered and summarized several effective methods for scale removal. These techniques are recommended for professionals or those who understand boiler maintenance.
Scale buildup is a critical concern in industrial boilers. If left untreated, it can cause overheating, corrosion, and even catastrophic failures. Therefore, it’s essential to take proper measures to prevent or remove scale. Here are some proven methods:
One approach is to use chemical descaling methods, which should be carried out by trained boiler maintenance personnel. The process involves analyzing the composition and thickness of the scale before selecting the appropriate treatment. A common method is to add trisodium phosphate into the boiler water. Typically, 50 kg of trisodium phosphate is added per ton of water. After filling the boiler with water and maintaining pressure for about three days, the solution is drained, and the remaining scale is manually removed.
Although this method may not be the most advanced, it is practical, cost-effective, and highly efficient for dealing with scale buildup. Many industrial facilities still rely on this technique due to its simplicity and reliability.
In addition to chemical cleaning, regular maintenance and monitoring of water quality can help prevent scale formation. Using soft water or implementing water treatment systems can significantly reduce the risk of scale accumulation.
If you're facing boiler scale issues, consider these methods as part of your maintenance plan. Always ensure that any chemical treatments are performed safely and according to manufacturer guidelines.
