Boiler Water Tests | Viking Water Technology, Inc.

May 04, 2016 · For boilers operating up to 300 psig, the accepted alkalinity range is 200 ppm to 700 ppm, with P being 60% to 80% of Total Alkalinity. Balances alkalinities are no guarantee of clean, trouble-free boilers. However, this is one of the important factors, together with others, that must be properly controlled if the boiler is to be kept clean.

standard conductivity for steam boiler

conductivity samples as will be discussed later. It is also the reason that conductivity correlates closely with pH in some samples. One practice for determining total dissolved solids in low pressure industrial boilers takes into consideration the high conductance of the hydroxide ion in high pH phosphate and/or caustic treatment.

Conductivity Measurement in Boiler Water Treatment

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)

Steam Purity

cation conductivity analyzer is often used to take out the CO2 from the reading. Degassed cation conductivity readings should be < 0.3 uS/cm or for a supercritical < 0.15 uS/cm. Overfeed of amine to the system will distort the true cation conductivity reading since it is the major source of CO2 in the steam.
