The Importance of Boiler Water and Steam Chemistry

Conventional shell boilers are normally operated with the TDS in the range of 2 000 ppm for very small boilers, and up to 3 500 ppm for larger boilers, provided the: Boiler is operating near to its design pressure. Steam load conditions are not too severe. Other boiler water conditions are correctly controlled.

Operation of Boiler and Conductivity in Drum Water and …

24/2/2016 · 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)
