Abstract
In a steam turbine, the presence of water slugs can have an adverse effect on certain turbine parts. One particular area of concern is the low-pressure end of the turbine wherein excess moisture is more likely to occur. Another source of moisture is an extraction line interconnecting a turbine stage with a feedwater heater. It is possible for wet steam and/or water slugs to travel from the feedwater heater to the turbine and vice-versa. The present invention provides a monitoring device for a steam conduit which detects the presence of water slugs or wet steam in a steam conduit and will further indicate a reverse direction of flow in the steam conduit.
