Conductivity (electrolytic) - Wikipedia

For example, conductivity measurements are used to monitor quality in public water supplies, in hospitals, in boiler water and industries which depend on water quality such as brewing. This type of measurement is not ion-specific; it can sometimes be used to determine the amount of total dissolved solids (T.D.S. or TDS) if the composition of the solution and its conductivity behavior …

Methods of Detecting Water Level in Steam Boilers | Spirax Sarco

A standard conductivity probe must be used to provide low water alarm in a boiler. Under UK regulations, this must be tested daily. For a simple probe there is a potential problem - If dirt were to build up on the insulator, a conductive path would be created between the probe and the metal tank and current would continue to flow even if the tip of the probe were out of the water.

Water Handbook - Boiler Blowdown Control | SUEZ

If an economical blowdown rate is to be maintained, suitable boiler water tests must be run frequently to check concentrations in the boiler water. When sodium zeolite softened makeup is used, the need for boiler blowdown is usually determined by measurement of the boiler water conductivity, which provides an indirect measure of the boiler water dissolved solids.

2015/5/5 · It is necessary to treat the boiler water to produce protective coat on the tubes required for good quality water & steam. For this it is necessary that the water shall be low controlled alkaline, very low level of dissolved Oxygen and very low presence of ions like Cl–. Silica from CW is another damaging factor as it deposits on turbine.

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Boiler Water Conductivity Measurement Fundamentals - Yamatho …

2016/2/24 · 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: σ T = σ25 [1 + α (T – 25)] σT = Conductivity at temperature T (µS / cm) α = Temperature coefficient, per °C (Typically 0.02 / °C or 2%°C)
