Abstract: A system and method capable of performing online corrosion monitoring of a component installed in a gas turbine. A sensing device is located so that electrodes thereof are exposed to an operating environment within the gas turbine section containing the component. The electrodes are formed of a material so that the component and electrodes similarly respond to corrosive agents within the gas turbine section. The electrodes are electrically insulated from each other and each electrode is operable as an anodic electrode or a cathodic electrode, depending on the extent of corrosion thereat, so that each electrode has an electrical potential value, voltages exist across the electrodes, electric currents flow between the electrodes, and the electrical potential/current values correspond to corrosion behaviors at the anodic electrodes.

Abstract: An embodiment of the present invention provides an air sampling system for measuring corrosives within an airstream flowing within an inlet system. This air sampling system may include an air sampling unit with a plurality of sampling coupons secured within. Parts of the air sampling system may be externally mounted to the inlet system, allowing for an operator to access the sampling coupons, while the inlet system operates. In operation, an embodiment of the present invention has a sampling line connected to the air sampling system; the airstream flowing within the sampling line passes over the sampling coupons and then returns to the inlet system.
