Why a RO System is necessary for Boiler Feed Water Pretreatment

Advantages:

–  Reduce fuel costs through lower heat loss and increased boiler cycles. Reducing the total dissolved solids (TDS) in the RO product water can increase the boiler’s cycles of concentration. The boiler will also have a cleaner heat transfer surface and is more efficient.  
–  Improve operation and steam purity. Steam quality is improved because you are providing better quality feedwater to the boiler. Any control valves, pumps, or compressors that have direct steam contact are less prone to failure. There are no concerns with contaminated products because the steam is pure.
–  Reduce chemical costs. The amount of boiler feed chemicals required to prevent condensation corrosion is less due to lower alkalinity in the boiler makeup water.
–  Control return-line corrosion. Corrosion is one of the main reasons for boiler down time. Maintaining the proper pH and alkalinity levels will help control corrosion.
–  Extending equipment life. Oxygen, iron, and copper levels should be very low and pH should be maintained between 8.5 and 9.5 to protect the boiler system.
