Description

The purpose of the study is to collect data in order to make models that are applicable to calculate carryover droplets that are generated in and flow out of a steam separator. Various effective tests relevant to separation mechanisms in the separator have been conducted with a full-scale steam separator under atmospheric pressure. Separation behaviors for the top of the riser of the separator and for corrugated-separator were clarified and correlated by the experiment. Distinct patterns about the separation at the corrugated-separator, the separation of discharged droplets by gravity, and the separation of droplets by a screen dryer that is used to dry up the steam were also measured with the facility using a full-scale separator in a vessel simulating the flow area of ATR under the high-pressure and high-temperature condition for various water levels. Each separation data were correlated under the condition of maximum steam and liquid flow rates of 7 and 30.5 kg/s, respectively. Liquid droplets containing a small amount of LiOH at several positions were sampled together with steam by iso-kinetic probes, and the amount of carryover was analyzed in PPT range by the chemical analysis of condensed steam. As a result, basic data for separation mechanisms were obtained, and maximum capacity of the separator was estimated.
