摘要： Gas turbine inlet guide vane ice detection and control systems and methods that utilize active infra-red monitoring of inlet guide vanes, detection of ice formation on the guide vanes and elimination of the ice by altering properties of the gas turbine inlet intake airflow, such as by introducing compressed and/or heated air bled from the turbine. Ice has lower detectable emissivity intensity in the infra-red spectrum than ice-free inlet guide vane surfaces. Ice formation is inhibited by direct monitoring of inlet guide vane icing conditions, rather than by indirect empirical assumptions of ice formation based on atmospheric condition monitoring. Direct monitoring mitigates ice formation in real time without reliance on excessive use of gas turbine compressed or heated air bleed, which enhances turbine operational efficiency.

摘要： An on-line optical inspection and monitoring system is externally mounted to existing man way service access within the combustor housing. A replacement man way cover having an optical window is mounted to the combustor housing. One or more optical cameras are oriented so that the camera field of view (FOV) is directed through the man way cover optical window. The camera FOV is moved to plural positions within the combustion section, such as under control of an automated motion control system, and images are captured. Multiple images are combined to form a composite image, which may include an image of an entire transition within the combustion section. Visual images and/or infrared (IR) thermal images may be captured. Thermal image information is correlated with component temperature. Image information is utilized to determine vibration characteristics of the imaged components.

摘要： Turbine blade tip clearance is measured in a fully assembled turbine casing by mounting a contact or non-contact displacement probe on a turbine blade that generates data indicative of probe distance from the turbine casing that circumferentially surrounds the blade. Variations in probe distance data are recorded as the blade circumferentially sweeps the turbine casing when the turbine is operated in turning gear mode. Blade rotational position data are collected by a rotational position sensor. A data processing system correlates the distance and rotational position data with localized blade tip gap at angular positions about the turbine casing circumference. An optical camera inspection system may be coupled to a turbine blade to obtain visual inspection information within the turbine casing. This method and apparatus provide an accurate and cost effective solution for accessing turbine casing deformation impact on blade tip clearance and rotor/casing alignment.

摘要： Internal components of power generation machinery, including for example gas or steam industrial turbines as well as generators, are inspected a camera inspection system that is inserted and positioned within the machinery by an elongated cable carrier that has restricted cable flexure along a two-dimensional carrier cable flexure motion plane. A camera head that retains the camera is coupled to a distal end of the cable carrier. Embodiments also include a connector block coupled between the cable carrier distal end and the camera head. The connector block has a pivot axis coupled to the camera head for swinging the camera head along a camera head range of motion path that intersects the cable carrier flexure motion plane. Embodiments include a camera head swing motion drive system for selectively positioning the camera head along the camera head range of motion path.

摘要： Internal components of gas or steam turbines are inspected with a 3D scanning camera inspection system that is inserted and positioned within the turbine, for example through a gas turbine combustor nozzle port. Three dimensional internal component measurements are performed using projected light patterns generated by a stripe projector and a 3D white light matrix camera. Real time dimensional information is gathered without physical contact, which is helpful for extracting off-line engineering information about the scanned structures. Exemplary 3D scans, preferably with additional visual images, are performed of the gas path side of a gas turbine combustor support housing, combustor basket and transition with or without human intervention.

摘要： An object in a hot atmosphere with a temperature greater than 400 F in a gas turbine moves in a 3D space. The movement may include a vibrational movement. The movement includes a rotational movement about an axis and a translational movement along the axis. Images of the object are recorded with a camera, which may be a high-speed camera. The object is provided with a pattern that is tracked in images. Warpings of sub-patches in a reference image of the object are determined to form standard format warped areas. The warpings are applied piece-wise to areas in following images to create corrected images. Standard tracking such as SSD tracking is applied to the piece-wise corrected images to determine a movement of the object. The image correction and object tracking are performed by a processor.
