  • Cooling Water and Boiler Feed Water | Hach

    Cooling water. Cooling water is used in industrial processes to dissipate large amounts of heat. Boiler feed water, on the other hand, is used in the water/steam circuit for electricity generation in power stations. The water has to meet specific requirements for both applications, which is why it is analyzed on a regular basis.Learn More

  • Boiler water chemistry - Properties of feed water explored

    Jul 16, 2009 · For boiler water PH is maintained between 11-11.8 and that of feed water between 7-9. If either of the values increases, water will accordingly become acidic or alkaline, leading to detrimental effects caused due to acidic attack or caustic embrittlement. This may damage the boiler completely. 2. Hardness.Learn More
