BASIC WATER TREATMENT OF STEAM BOILERS

May 02, 2000 · The impurities found in the makeup water will build up in the boiler as the water turns to steam leaving most impurities behind. There are known maximum limits for these impurities, which can and will be surpassed without proper blow down. The maximum concentration allowable by the limits can be expressed as the maximum cycles for that water

Boiler Water Conductivity Measurement Fundamentals

Feb 24, 2016 · 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)
