Abstract

In spite of their relatively simple design, once-though-steam generators (OTSG) with integral economizer (IE) continue to present a challenge to the analyst wanting to make best estimate predictions of their behavior under a variety of actual and postulated conditions. This is due in part to the wide spectrum of flow and heat transfer conditions which are encountered in many common cases. By comparison with the U-tube steam generator, the OTSG responds more strongly and promptly to feed-flow variations as well as secondary pressure variations and its secondary fluid inventory is significantly smaller, thus making it more susceptible to dry-out.
