THEORY AND APPLICATION OF CONDUCTIVITY

Conductivity is also used to monitor the build up of dissolved ionic solids in evaporative cooling water systems and in boilers. When theconductivity gets too high, indicating a potentially harmful accumula-tion of solids, a quantity of water is drained out of the system and replaced with water having lower conductivity. • Leak detection.

Controlling TDS in the Boiler Water | Spirax Sarco

An increase in temperature results in an increase in electrical conductivity. For boiler water, the conductivity increases at the rate of approximately 2% (of the value at 25°C) for every 1°C increase in temperature. This can be written as: Example 3.12.3. A boiler water sample has an unneutralised conductivity of 5 000 μS/cm at 25°C.

Scaling in boilers - Lenntech

Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots. Leading to local overheating. Scaling mechanism is the exceeding of the
