    Abstract

    Conductivity measurement (1, 2) to determine steam or condensate purity has been used extensively for many years in steam-electric generating stations and has been an excellent guide in many cases. However, with varying amounts of ammonia present in the steam-water cycle, evaluation has been difficult, particularly in steam of very low dissolved solids content. In the past, the calorimetric measurement of steam quality has provided important information; however in the modern plant, the calorimeter is not considered sufficiently sensitive, particularly at elevated pressures. Steam quality, as determined calorimetrically refers to the moisture content as H2O, whereas steam purity refers to ingredients other than H2O which may be present.
