Description

Technical Field

[0001] The present invention relates to the field of gas turbines, and in particular to an anti-vibration ring device with a replaceable inner wall and a combustion chamber component. Background Art

[0002] Gas turbines are a key component of today's energy and power generation sector, widely used in aviation, marine, and power generation. The gas turbine combustor is the core component and power source of the entire gas turbine. However, to meet increasingly stringent emission standards and reduce emissions, primarily nitrogen oxides (NOx), advanced gas turbine combustors often utilize lean premixed combustion technology. These combustors often operate near flameout, making them highly sensitive to external disturbances and susceptible to heat release rate fluctuations. When heat release rate fluctuations within the combustor couple with the acoustics of the combustion system (e.g., satisfying the Rayleigh criterion), they can easily cause large heat release rate and pressure fluctuations. These large pressure and heat release fluctuations within the combustor can potentially damage the combustor structure, potentially compromising the stable and safe operation of the combustor and, ultimately, the gas turbine system. Therefore, combustion oscillations must be minimized in modern advanced gas turbines.

[0003] To address combustion oscillations within gas turbine combustors, various methods have been proposed and applied to control combustion oscillations. These methods can be categorized into two main types, active and passive, based on their principles. Active control uses specialized signal monitors to monitor pressure or heat release pulsations within the combustor. Based on these pressure pulsations and other signals, appropriate actuators are used to apply appropriate external excitations (such as to the inlet air or fuel supply) to suppress or eliminate the coupling between heat release rate pulsations and pressure oscillations (acoustic waves). However, these methods require additional control systems and actuators, placing high demands on control algorithms, increasing costs and limiting their applicability. Passive control involves the addition of fixed devices to the combustion system to suppress or eliminate combustion oscillations. Common examples include various acoustic components, such as Helmholtz resonators, which can suppress combustion oscillations at specific frequencies. However, these methods are bulky, effective only at specific frequencies, and require extensive experimentation and debugging.

[0004] Existing combustion chamber endwall structures often utilize a sudden expansion perpendicular to the swirl flow path. This sudden expansion creates a corner vortex recirculation zone, a primary cause of combustion oscillation in conventional gas turbine combustors. Conventional methods for controlling combustion oscillations suffer from system complexity, high component and algorithm requirements, and limited applicability. Summary of the Invention

[0037] Figure 1 The cross-sectional structure schematic diagram of the inner wall replaceable anti-vibration ring device provided by the present application is illustrated, Figure 2 The front view structure schematic diagram of the inner wall and outer wall of the anti-vibration ring end wall provided by the present application is illustrated, Figure 1 and Figure 2As shown, the vibration-isolating ring device with a replaceable inner wall includes a swirl channel outer ring 100, a center body 200, a swirler 300, a flame tube 600, an inner end wall 400 of the vibration-isolating ring, and an outer end wall 500 of the vibration-isolating ring. The center body 200 is disposed within the swirl channel outer ring 100; the swirler 300 is disposed within the swirl channel outer ring 100 and connected to the center body 200. One side of the inner end wall 400 of the vibration-isolating ring is sleeved onto the outer circumference of one end of the swirl channel outer ring 100. The outer wall 500 of the vibration-isolating ring end wall surrounds the outer periphery of the inner wall 400 of the vibration-isolating ring end wall. A predetermined distance separates the outer wall 500 from the inner wall 400. The side of the outer wall 500 of the vibration-isolating ring end wall near the swirl channel outer ring 100 is detachably connected to the side of the inner wall 400 of the vibration-isolating ring end wall. Both the outer wall 500 of the vibration-isolating ring end wall and the inner wall 400 of the vibration-isolating ring end wall form an acute angle with the central axis of the center body 200. The side of the outer wall 500 of the vibration-isolating ring end wall away from the swirl channel outer ring 100 is connected to the flame tube 600.

[0038] The present invention provides a vibration-proof ring device with a replaceable inner wall, which reduces the formed angular vortex recirculation zone by making the outer wall 500 of the vibration-proof ring end wall and the inner wall 400 of the vibration-proof ring end wall form an acute angle with the central axis of the central body 200; since the side of the outer wall 500 of the vibration-proof ring end wall close to the outer ring 100 of the swirl channel is detachably connected to the side of the inner wall 400 of the vibration-proof ring end wall, the outer wall 500 of the vibration-proof ring end wall and the inner wall 400 of the vibration-proof ring end wall with different parameters can be replaced, thereby optimizing the relevant structural parameters of the outer wall 500 of the vibration-proof ring end wall and the inner wall 400 of the vibration-proof ring end wall, and then optimizing the flow and flame characteristics in the combustion chamber, thereby enhancing the flame stabilization ability in the combustion chamber, stabilizing the flame in the vibration-proof ring, and finally realizing the regulation of combustion oscillation.

[0039] In one embodiment of the present invention, Figure 3 One of the schematic side cross-sectional structures of the inner wall of the end wall of the anti-vibration ring and the outer wall of the end wall of the anti-vibration ring provided by the present invention is illustrated, as shown in FIG. Figure 3 As shown, the inner diameter of the inner wall 400 of the anti-vibration ring end wall and the inner diameter of the outer wall 500 of the anti-vibration ring end wall both gradually increase in the direction away from the outer ring 100 of the swirl channel. Figure 3 As shown, the inner diameters of the inner wall 400 and the outer wall 500 of the vibration isolation ring end wall gradually increase from left to right. The thickness of the inner wall 400 and the outer wall 500 can be the same or different; preferably, the thickness of the inner wall 400 is less than the thickness of the outer wall 500.

[0040] In one embodiment of the present invention, the cross-section of the outer wall 500 of the vibration isolation ring end wall and the cross-section of the inner wall 400 of the vibration isolation ring end wall are both circular. Of course, the cross-sectional shape of the outer wall 500 of the vibration isolation ring end wall and the cross-sectional shape of the inner wall 400 of the vibration isolation ring end wall are not limited to this and can also be other shapes.

[0041] In one embodiment of the present invention, Figure 3 As shown, the center body 200 is coaxially arranged with the swirl channel outer ring 100. The included angle α between the inner wall 400 of the anti-vibration ring end wall and the central axis of the center body 200 is . The included angle β between the outer wall 500 of the anti-vibration ring end wall and the central axis of the center body 200 is 0°≤α≤90°, 0°≤β≤90°, and -5°≤α-β≤+5°.

[0042] In one embodiment of the present invention, the central axis of the outer wall 500 of the vibration isolation ring end wall is aligned with the central axis of the inner wall 400 of the vibration isolation ring end wall, that is, the outer wall 500 of the vibration isolation ring end wall is coaxially arranged with the inner wall 400 of the vibration isolation ring end wall.

[0043] In one embodiment of the present invention, Figure 3 As shown, an inner wall 400 of the anti-vibration ring end wall has an anti-vibration ring inlet 410 on one side. The anti-vibration ring inlet 410 is a circular opening and is coaxially arranged with the air passage inside the outer ring 100 of the swirl channel. The radius of the anti-vibration ring inlet 410 is r, and the width of the outer wall 500 of the anti-vibration ring end wall in the longitudinal direction of the central axis of the cyclone 300 is L1, and 0≤L1 / r≤2.

[0044] It should be noted that the width of the outer wall 500 of the anti-vibration ring end wall in the longitudinal direction of the central axis of the cyclone 300 specifically refers to the length of the projection of the outer wall 500 of the anti-vibration ring end wall on the central axis of the cyclone 300, that is, Figure 3 The length of the midline segment L1.

[0045] In one embodiment of the present invention, Figure 3 As shown, the width of the inner wall 400 of the vibration isolation ring end wall along the lengthwise direction of the central axis of the cyclone 300 is L2, where 0≤L2 / r≤2. The width of the outer wall 500 of the vibration isolation ring end wall along the lengthwise direction of the central axis of the cyclone 300 is greater than the width of the inner wall 400 of the vibration isolation ring end wall along the lengthwise direction of the central axis of the cyclone 300, that is, L1 is greater than L2, and therefore 0≤L2 / L1≤1.

[0046] It should be noted that the width of the inner wall 400 of the anti-vibration ring end wall in the longitudinal direction of the central axis of the cyclone 300 specifically refers to the length of the projection of the inner wall 400 of the anti-vibration ring end wall on the central axis of the cyclone 300, that is, Figure 3 The length of the midline segment L2.

[0047] The inner wall replaceable anti-vibration ring device provided by the application can realize the regulation and control of combustion oscillation in the gas turbine combustion chamber by adjusting the local structure of the original combustion chamber (i.e., adjusting the structural parameters of the outer wall 500 of the anti-vibration ring end wall and the inner wall 400 of the anti-vibration ring end wall) without increasing the weight of the gas turbine combustion chamber, and can realize the rapid optimization of the anti-vibration ring end wall structure scheme by the replaceable structure of the outer wall 500 of the anti-vibration ring end wall and the inner wall 400 of the anti-vibration ring end wall.

[0048] The inner wall replaceable anti-vibration ring device provided by the application is designed according to the principle of passive control, and a replaceable anti-vibration ring end wall structure of the outer wall 500 of the anti-vibration ring end wall and the inner wall 400 of the anti-vibration ring end wall is realized by adjusting the structure of the combustion chamber to weaken or eliminate the heat release pulsation in the combustion chamber and enhance the flame stability in the combustion chamber, thereby realizing the regulation and control of combustion oscillation.

[0049] In one embodiment of the application, Figure 5 One of the side view cross-sectional structure schematic diagrams of the inner wall of the anti-vibration ring end wall and the outer wall of the anti-vibration ring end wall provided by the application is shown in the figure, Figure 5 As shown in the figure, at least one set of impact holes is arranged on the side of the outer wall 500 of the anti-vibration ring end wall close to the outer ring 100 of the swirl passage, and the set of impact holes includes a plurality of impact holes 510. The impact holes 510 are circular through holes, and the plurality of impact holes 510 are arranged at intervals in the circumferential direction, and the distance between adjacent two impact holes 510 is equal. Of course, the distance between adjacent two impact holes 510 can also be unequal, which is determined according to the actual effect. At least one set of multi-inclined holes is arranged on the side of the outer wall 500 of the anti-vibration ring end wall away from the outer ring 100 of the swirl passage, and the set of multi-inclined holes includes a plurality of multi-inclined holes 520. The multi-inclined holes 520 are circular through holes, and the plurality of multi-inclined holes 520 are arranged at intervals in the circumferential direction, and the distance between adjacent two multi-inclined holes 520 is equal. Of course, the distance between adjacent two multi-inclined holes 520 can also be unequal, which is determined according to the actual effect.

[0050] The impact holes 510 on the side of the outer wall 500 of the anti-vibration ring end wall close to the outer ring 100 of the swirl passage are used to cool the anti-vibration ring end wall inner wall 400 in the overlapping area of the anti-vibration ring end wall outer wall 500 and the anti-vibration ring end wall inner wall 400. The multi-inclined holes 520 on the side of the outer wall 500 of the anti-vibration ring end wall away from the outer ring 100 of the swirl passage are used to cool the anti-vibration ring end wall outer wall 500. According to the cooling object, the cooling area can be divided into two areas, i.e., the combined area formed by the overlapping part of the anti-vibration ring end wall inner wall 400 and the anti-vibration ring end wall outer wall 500, and the outer wall independent area formed by the protruding part of the anti-vibration ring end wall outer wall 500 relative to the anti-vibration ring end wall inner wall 400, wherein the combined area is cooled by the impact holes 510, and the outer wall independent area is cooled by the multi-inclined holes 520.

[0051] In one embodiment of the application, as Figure 5 As shown, the central axis of the impact hole 510 is perpendicular to the outer surface of the inner wall 400 of the vibration isolation ring end wall. Air entering through the impact hole 510 directly contacts the outer surface of the inner wall 400 of the vibration isolation ring end wall for heat exchange, thereby cooling the inner wall 400 of the vibration isolation ring end wall. The central axis of the multi-slant hole 520 is parallel to the central axis of the central body 200. When air passes through the multi-slant hole 520, it removes heat from the outer wall 500 of the vibration isolation ring end wall.

[0052] In one embodiment of the present invention, at least one ring of impact holes 510 in the impact hole group and at least one ring of multi-slant holes 520 in the multi-slant hole group are arranged alternately along the circumferential direction. The region where the impact holes 510 and multi-slant holes 520 alternate corresponds to the side of the inner wall 400 of the anti-vibration ring end wall that is away from the outer ring 100 of the swirl channel. By alternating the impact holes 510 and multi-slant holes 520, both the inner wall 400 and the outer wall 500 of the anti-vibration ring end wall in this region can be cooled.

[0053] like Figure 1 As shown, in this embodiment, the outer wall 500 of the vibration isolation ring end wall is provided with three circles of impact hole groups and two circles of multi-slant hole groups. Impact holes 510 in one circle of the impact hole group are alternately arranged circumferentially with multi-slant holes 520 in another circle of the multi-slant hole group. Of course, the number of impact hole groups and multi-slant hole groups is not limited to this, and is determined by the width of the inner wall 400 of the vibration isolation ring end wall.

[0054] In one embodiment of the present invention, Figure 4 Example Figure 3 The schematic diagram of the local enlarged structure at A in the middle is as follows: Figure 4 As shown, the side of the outer wall 500 of the anti-vibration ring end wall near the outer ring 100 of the swirl channel is connected to the side of the inner wall 400 of the anti-vibration ring end wall via threads. Specifically, the inner wall of the outer wall 500 of the anti-vibration ring end wall near the outer ring 100 of the swirl channel is provided with internal threads, and the outer peripheral surface of the inner wall 400 of the anti-vibration ring end wall is provided with external threads. The internal and external threads cooperate to achieve a detachable connection between the outer wall 500 of the anti-vibration ring end wall and the inner wall 400 of the anti-vibration ring end wall. Of course, the connection method between the outer wall 500 of the anti-vibration ring end wall and the inner wall 400 of the anti-vibration ring end wall is not limited to this, and screws, tongue and groove, or other detachable connection methods can also be used. Since the side of the outer wall 500 of the anti-vibration ring end wall close to the outer ring 100 of the swirl channel is detachably connected to the side of the inner wall 400 of the anti-vibration ring end wall, the combustion oscillation in the combustion chamber can be controlled without increasing the weight of the combustion chamber by replacing the outer wall 500 and the inner wall 400 of the anti-vibration ring end wall with different parameters.

[0055] The vibration-proof ring device with a replaceable inner wall provided by the present invention can adjust the parameters of the outer wall 500 of the vibration-proof ring end wall and the inner wall 400 of the vibration-proof ring end wall (such as the angle, width, and the setting method of the impact hole 510 and the multi-inclined hole 520) individually or in combination according to the actual needs of the combustion chamber, thereby realizing the change of the swirl flow parameters and flame-related parameters in the combustion chamber, thereby enhancing flame stability and realizing the regulation of combustion oscillations.

[0056] The present invention further provides a combustion chamber component, which includes the anti-vibration ring device with a replaceable inner wall as described in any one of the above embodiments.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
