Abstract (en)

Any moisture present in a steam flow outletting from a high pressure steam turbine and before that flow is passed to the inlet of a low pressure turbine, is removed by passing the flow through a high velocity separator [30], this separator being a type in which at entry thereto vanes [40] cause vortex-like swirling of the steam flow so that moisture therein is centrifuged against an inner wall surface [44] of a separator housing from thence being carried forward in flow direction to outlet from the housing via a skimmer slot [46] in the housing wall located intermediate the housing ends. The steam flow from which the moisture has been separated, passes to an outlet end of the housing [36] but before making its exit therefrom passes through straightening vanes [52] which reorient the flow from vortex-like swirling to longitudinal straight line course thereof. <IMAGE>
