    Abstract

    The 1941 Symposium on Steam Quality marked the transition from determining the moisture in steam by measuring the temperature drop and reporting it in terms of percentage, to the determination of parts per million contamination and measuring it by conductivity instruments. Conductivity measurements with necessary corrections for dissolved gases had given most of the answers needed. With the introduction of higher pressures and higher steam temperature which resulted in the vaporization of dissolved solids in the boiler water, the need for a more sensitive and accurate measurement has been noted. Also the introduction of the once-through and the supercritical pressure boilers make obsolete the present methods for determining steam quality. The purpose of this symposium is to review present practices and introduce new techniques that will aid in obtaining the answer that is needed for the determination of steam purity in modern steam generators. The new techniques should give a more accurate picture of the solids that are vaporized as well as the solids that are carried over by mechanical means.
