Assignee:
General Electric Company - Schenectady NY
International Classification:
G01N 1/22
US Classification:
7386323
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.

System And Method For Online Monitoring Of Corrosion

US Patent:
7982474, Jul 19, 2011
Filed:
Apr 9, 2010
Appl. No.:
12/757659
Inventors:
Rebecca Evelyn Hefner - Simpsonville SC, US
Paul Stephen DiMascio - Greer SC, US
George Albert Goller - Greenville SC, US
Assignee:
General Electric Company - Schenectady NY
International Classification:
G01R 27/08
US Classification:
324700, 324713
Abstract:
A system and method for online monitoring of corrosion of a pressure vessel is disclosed. First and second electrodes may be isolated from each other in a wall of the pressure vessel and exposed to a corrosive environment within the pressure vessel. Additionally, the first and second electrodes may be electrically coupled such that, when an electrical potential difference exists between the electrodes, an electrical current flows between the first electrode and the second electrode. The electrical potential difference and/or the electrical current flowing between the electrodes may then be measured and analyzed to determine when to perform a corrective action on the pressure vessel.

Rebecca E. Hefner - Greenville SC, US
Ronald R. Cairo - Greer SC, US
Assignee:
General Electric Company - Schenetady NY
International Classification:
B01D 19/00
US Classification:
95 30, 96175, 422128, 528502 R
Abstract:
A method and system for degassing a resin is provided. A degassing trough retains the resin, and an ultrasonic energy source applies ultrasonic energy to the degassing trough and resin. The application of ultrasonic energy to the resin reduces the amount of trapped gas bubbles contained within the resin.

System And Method For Online Monitoring Of Molten Salt Corrosion

US Patent:
8224595, Jul 17, 2012
Filed:
Apr 9, 2010
Appl. No.:
12/757636
Inventors:
Rebecca Evelyn Hefner - Simpsonville SC, US
Paul Stephen DiMascio - Greer SC, US
Assignee:
General Electric Company - Schenectady NY
International Classification:
G01N 27/04
US Classification:
702 57, 324700, 204404, 204412, 204422, 204408, 20419602, 204419, 2057755, 205793, 2057945, 205786, 700275, 700287, 700288
Abstract:
A system and method for online monitoring of molten salt corrosion of a component of an apparatus is disclosed. First and second electrodes are electrically isolated from each other within the component and exposed to a corrosive operating environment of the apparatus. The first and second electrodes are electrically coupled such that when an electrical potential difference exists between the first and second electrodes an electrical current flows between the first electrode and the second electrode. The electrical potential difference between the first electrode and the second electrode is based at least in part on molten salt corrosion at the first electrode or the second electrode. At least one of the electrical potential difference or the electrical current flowing between the first electrode and second electrode is measured and analyzed such that a corrosion characteristic of the component can be predicted.

System And Method For Online Monitoring Of Corrosion Of Gas Turbine Components

US Patent:
8475110, Jul 2, 2013
Filed:
Jul 30, 2009
Appl. No.:
12/512618
Inventors:
Rebecca Hefner - Greenville SC, US
Jeff P. Czapiewski - Greer SC, US
Assignee:
General Electric Company - Schenectady NY
International Classification:
F01D 21/10
F01D 25/00
US Classification:
415 1, 415116, 415118, 416 61, 134 18, 134 2218, 134 34, 324700, 204404, 2057755, 2057765, 205777
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. During gas turbine operation, output signals are obtained from the sensing device and indications are provided as to when certain maintenance operations should be performed on the gas turbine.
