Method and system for steam purity monitoring through use of high electron mobility transistors

Abstract

A method or system for steam purity monitoring in a steam powered turbine includes providing a chloride-sensing device in a steam flow path; generating a signal from the chloride-sensing device indicative of a concentration level of chloride ions in a steam flow; and indicating a concentration level of chloride ions in a steam flow. The steam turbine includes a rotor, a rotating shaft and a plurality of axially spaced rotor wheels. A plurality of rotating blades is mechanically coupled to each rotor wheel. A chloride-sensing device is disposed in a steam flow path. A controller is arranged to generate a signal from the chloride-sensing device indicative of a concentration level of chloride ions in a steam flow and indicate a concentration level of chloride ions in a steam flow.
