Definitions
- the invention relates to a remote-controlled inspection device for an annular combustion chamber of a gas turbine.
- the invention further relates to a method for inspecting an annular combustion chamber of a gas turbine.
- a device for inspecting tubes is known from US Pat. No. 4,255,762.
- An optical system for taking test images of the inner surface of the tube is mounted on a test head of the device.
- the test device has a positioning mechanism with which the test head can be moved in translation and rotation.
- video images can be displayed in a tube surface.
- the probe is guided in the tube without contact using a distance sensor.
- DE 41 32 281 AI shows a drive unit for driving through a pipeline.
- the drive unit has a drive, a plurality of sun wheels driven by the drive for rotation, in each case at least 2 planet wheels meshing with each sun wheel and a plurality of drive wheels with running surfaces. The treads are pressed against the inner wall surface of the tube by the orbital rotation of the planet gears.
- a driving probe which is operated as an inspection device for driving through a pipeline network with bends and branches, consists of the coupling of two of the drive units described above.
- the drive units are mounted on the front and rear ends of a flexible device. This enables a smooth passage through a pipeline network.
- the object of the invention is to specify how the inspection of an annular combustion chamber of a gas turbine can be carried out quickly, inexpensively and in a particularly effective manner with regard to reliable fault detection.
- a remote-controlled inspection device for an annular combustion chamber of a gas turbine which includes a remotely steerable drive mechanism, a movable video camera, a lighting device, a support frame for the video camera, the drive mechanism and the lighting device, and means for transmitting video images of the video camera has an evaluation.
- a combustion chamber of a gas turbine is a very thermally highly stressed area.
- Such a combustion chamber has a heat-resistant inner lining.
- This inner lining is subject to considerable oxidation and corrosion. This leads to wear, which must be recognized at an early stage before there is consequential damage induced by wear.
- complex coating systems for protecting the inner lining are often applied to them. Local chipping of this coating must be detected early and reliably.
- Gas turbine burners which are also exposed to extremely high thermal loads, flow into the combustion chamber. In particular, the swirl grille of such a burner, which serves to generate a backflow stabilizing the combustion, must be regularly checked for wear.
- the invention is based on the knowledge that such a remote-controlled inspection device with a video camera system offers considerable additional advantages over direct inspection, which have not been considered at all so far.
- the remote-controlled inspection device allows the entire annular combustion chamber to be inspected through a manhole access without opening the annular combustion chamber further. This leads to considerable reductions in revision times.
- the condition of the combustion chamber can be precisely documented with the help of the video system.
- a comparison with previous inspections and thus e.g. B. a control of the wear progress step rate possible and even quantifiable.
- the inspection is carried out according to an automated process and then the assessment of the state of wear of the individual areas is checked, for example, centrally in a know-how center. This also makes it possible to identify problem areas of the same type of gas turbines that exist across machines.
- the remote-controlled inspection device allows, if necessary, the exact assignment of positions of error areas by means of a position control. This means, for example, that the inspection data can be used to correct errors during subsequent maintenance.
- the drive mechanism preferably has an electric motor and wheels, at least one of which wheels can be driven by the electric motor.
- the inspection device is designed as a vehicle which moves independently through the ring combustion chamber on wheels.
- the drive mechanism preferably has a, in particular C-shaped, rail with which the supporting frame can be moved.
- the video camera mounted on the support frame with the lighting device is inserted into the combustion chamber via a C-shaped rail.
- This rail can, for example, be telescopically extendable.
- the drive mechanism preferably has an articulated arm on which the support frame is mounted.
- This embodiment corresponds in its mode of operation to the extent that the video camera and the lighting system are introduced into the ring combustion chamber via a suitable point, for example the manhole, and are remotely steered by the ring combustion chamber is directed. In this case, too, no further exposure of the ring combustion chamber is necessary.
- the object is further achieved according to the invention by a method for inspecting an annular combustion chamber of a gas turbine, in which a video camera is remotely steered into the annular combustion chamber and is pivoted such that video images of areas of the inner walls of the annular combustion chamber are recorded by the video camera, which video images are recorded an evaluation device positioned outside the annular combustion chamber can be transmitted.
- a video camera is remotely steered into the annular combustion chamber and is pivoted such that video images of areas of the inner walls of the annular combustion chamber are recorded by the video camera, which video images are recorded an evaluation device positioned outside the annular combustion chamber can be transmitted.
- FIG. 1 shows a longitudinal section through a gas turbine
- FIG. 2 shows an inspection device designed as a vehicle
- FIG. 3 shows an inspection device arranged on a telescopic rail
- FIG. 4 shows an inspection device with an articulated arm.
- a compressor 3, an Rmg combustion chamber 5 and a turbine part 7 are arranged in succession and connected to one another.
- the ring combustion chamber 5 forms an annular inner direction 9 through an inner inner wall 9 and an outer inner wall 11 Turbine part 7 narrowing annular space 10.
- a gas turbine burner 13 m mounts the annular combustion chamber 5.
- a first row of guide vanes 15 of the turbine part 7 is arranged.
- Ambient air 17 is compressed by the compressor 3 and fed to the gas turbine burner 13.
- the compressor air 17 is mixed with fuel in the gas turbine burner 13 and ignited in the annular combustion chamber 5.
- the resulting hot exhaust gas 19 is fed to the turbine part 7.
- the resulting temperatures of more than 1000 ° C put an extreme load on all components of the annular combustion chamber 5.
- the annular combustion chamber 5 is therefore provided with an inner lining, not shown here, which absorbs the thermal load from the hot exhaust gas 19.
- This inner lining consists, for example, of combustion chamber bricks, which can additionally be provided with a corrosion and oxidation protection layer and with a ceramic thermal insulation layer.
- the first guide vane row 15 and the orifice area of the gas turbine burner 13 are also subjected to extremely high thermal loads.
- the high thermal load leads to oxidation and corrosion and can, for example, B. also result in material removal, cracks, deformation, coking or flaking. Erosion by foreign bodies carried in the exhaust gas is also possible.
- a remote-controlled inspection device 21 is introduced into the annular combustion chamber 5.
- the inspection device 21 has a support frame 24.
- the support frame 24 is formed by a lower frame 23 and an upper frame 25.
- Four wheels 29 are mounted on both the lower frame 23 and the upper frame 25.
- a translation rail 31 is mounted on an end face of the inspection device 21.
- a video camera 33, together with an illumination device 35, is mounted on the torch-side end of the annular combustion chamber so that it can be moved in translation.
- the video camera 33 and the lighting device 35 are pivotally mounted in an articulated fork 37.
- the articulated fork 37 is rotatably supported on a shaft 39.
- a control and supply device 41 arranged on the shaft 39 serves to drive the movement for the video camera 33 and the electrical supply of the video camera 33 or the lighting system 35. Furthermore, the video signal can be pre-amplified in the control and supply unit 41. The video signal is routed out of the ring combustion chamber 5 via a line 43.
- the power supply for the control and supply device 41 also takes place via the line 43.
- the remote-controlled inspection device 21 enables a complete inspection of the annular combustion chamber 5 without complex covering or uncovering of the annular combustion chamber 5. This results in a considerable reduction in the revision time. Furthermore, the video recording of the combustion chamber status enables documentation that can be stored and is traceable regardless of location. Expert personnel can thus assess the condition of the annular combustion chamber 5 regardless of the location of the gas turbine 1. Furthermore, by comparing with older inspections, progress of wear and a quantification of the wear progress rate is possible. The remote-controlled inspection device 21 thus provides a spatial and temporal mapping of the state of the annular combustion chamber. Compared to a previously customary inspection by direct inspection, completely new possibilities for quantifying the thermally induced wear in the annular combustion chamber 5 thus result.
- the inspection device 21 has an electric motor 45.
- the electric motor 45 drives two of the wheels 29 via a shaft 47.
- the electric motor 45 is supplied with power via a supply line 49.
- the transmission of video images takes place via line 43, as in FIG. 1, line 43 being connected to an evaluation device 51.
- the evaluation device 51 has a monitor 53 on which the video images can be displayed directly.
- the evaluation device 51 also has a memory unit 55, via which the video images can be stored.
- video images of earlier inspections can be called up by the storage device 55.
- a location-synchronized, parallel display of the current inspection images with earlier inspection images can take place, so that a change in the state of wear is immediately visible.
- a power supply device 57 is used to supply power to the electric motor 45.
- FIG. 3 shows a further embodiment of the remote-controlled inspection device 21.
- the video camera 33 and the lighting system 35 are introduced into the annular combustion chamber 5 via a telescopically extendable rail 61.
- a manhole 63 serves as access.
- the rail 61 is C-shaped and can drive around half the circumference of the annular combustion chamber 5.
- Support frame 24 for the video camera 33 the lighting system 35 is either moved by means of the rail 61 through the annular combustion chamber 5 or the support frame 24 is mounted on the rail 61 in a mobile manner.
- FIG 4 shows a further embodiment of the inspection device 21.
- the support frame 24 for the video camera 33 and the lighting system 35 is moved by an articulated arm 71 through the annular combustion chamber.
