Abstract

Using data and information from the RheoVac® air in-leak monitoring system a determination has been made that quantifies properties of steam and non-condensable mixtures on the shell side of steam surface condensers.  These data are combined with condenser performance, geometry and steam load to understand the gas phase dynamics and how air in-leakage from different positions around the shell mixes with the turbine exhaust steam.  Regions of the condenser that deaerate are distinguished from regions that aerate the condensate.  These are directly related to measured amounts of dissolved oxygen.
