31. Electrical-Conductance Measurements of Water and Steam, and Applications in Steam Plants

Author

Hecht, Max and McKinney, D. S.

Abstract

In this paper a conductance method is presented for determining the concentration of salts in steam-plant water supplies. The method is applied to determine the purity of steam, of supplies used for boiler-feed purposes, and the concentration of boiler and evaporator water. The conductance data are refined by applying both a water and a CO2 correction. The method for establishing the CO2 correction is based on the preparation of a standard “synthetic” water, and eliminates the errors accompanying the chemical analysis of “pure” water. The conductance meter used may be calibrated in terms of dissolved salts. The relation of dissolved salts to conductance is discussed. Simple commercial equipment is used for measuring conductance. The data are obtained rapidly by the steam-plant personnel, and the results may be applied easily to the control of water conditions.
