Acoustic Monitoring Of Foreign Objects In Combustion Turbines During Operation
US Patent:
6668655, Dec 30, 2003
Filed:
Sep 27, 2001
Appl. No.:
09/965715
Inventors:
Ronald T. Harrold - Murrysville PA
Zal N. Sanjana - Mt. Lebanon PA
Brian D. Ottinger - Pittsburgh PA

Assignee:
Siemens Westinghouse Power Corporation - Orlando FL
International Classification:
G01N 2910
US Classification:
73660, 73593
Abstract:
A foreign object impact sensor for use with combustion turbines utilizes a passive acoustic waveguide within the turbine to receive acoustic signals from foreign object impact. The magnitude of these signals is displayed and or stored using a lighted display or other suitable indicating device. The information is also recorded and stored, so that a spectrum signature can be obtained from Fourier analysis.
Warning System For Turbine Component Contact

Assignee:
Siemens Power Generation, Inc. - Orlando FL
International Classification:
F01B 25/26
US Classification:
415118, 416 61
Abstract:
Aspects of the invention related to a system for providing advance notice of impending contact between a stationary component and a rotating component in a turbine engine. For example, the system can be used to warn of potential contact between a seal holder and a rotor disk in the compressor section of the engine. In one embodiment, a pad or other component can be provided on the stationary seal holder. If the seal holder and the rotor disk approach each other during operation, the pad can contact the rotor disk prior to actual contact between the seal holder and the rotor disk. An optical and/or an acoustic signal can be generated by such contact. The signals can be detected remotely from the point of contact by a signal detection device, thereby avoiding the need to pass wires through the compressor section.
