How can high dissolved solids in a boiler be corrected?

High dissolved solids in a boiler can lead to scaling, corrosion, and other operational issues that negatively impact efficiency and lifespan. The most effective way to correct this condition is through the process known as blowdown.

Blowdown involves the intentional removal of a portion of the water from the boiler along with the concentrated dissolved solids that have accumulated. This helps maintain the desired level of total dissolved solids (TDS) in the boiler water, thus ensuring optimal operation. By periodically removing a certain volume of water, the concentration of dissolved solids can be kept within acceptable limits, promoting better heat transfer and reducing the risk of damage to boiler components.

While chemical treatments can help manage dissolved solids to some extent, they do not physically remove them from the boiler water. Reducing water temperature does not address the issue of dissolved solids and may even exacerbate other problems. Increasing water flow might dilute the concentration temporarily, but it does not effectively manage the accumulation of dissolved solids over time. Therefore, blowdown remains the recommended and direct method to handle high levels of dissolved solids in boiler systems effectively.
