Boiler Blowdown Yokogawa Electric Corporation

This provides control of the water chemistry regardless of the boiler load conditions. Actual operation data verifies that automatic control can maintain boiler water conductivity consistently within 5% of the set point. Manual blowdown control cannot maintain this level of control more than 20% of the time.

Steam water analysis system - LinkedIn SlideShare

Why Conductivity Measured Conductivity is an important parameter for detecting any contamination of steam in the boiler circuit. Conductivity of pure water is almost zero (1-2 μ Siemens) Ingress of any kind of dissolved impurity will raise conductivity instantly. Thus conductivity is an important parameter for the detection of leakages.

Water - Soft, Hard, Alkaline, Acidic: Benefits/Dangers

Alkaline Water. Alkaline water at pH >8 may have a soda-like taste.. Most tap water has pH between 6.5 and 8.5 [18], but some municipal water suppliers may raise the pH of water to 9 to prevent plumbing corrosion [174]. Hard water, which is high in calcium and/or magnesium, is usually more alkaline than soft water. There seems to be no convincing evidence about health benefits or dangers of
