Description

Technical Field

[0001] The present invention relates to the technical field of boiler headers, and in particular to a peak-shaving boiler header assembly. Background Art

[0002] Under harsh operating conditions such as deep peak load regulation and start-stop peak load regulation, stress anomalies caused by abnormal expansion of power plant metal components are becoming increasingly apparent. This is especially true for boiler water-wall tubes and headers, where expansion is affected by peak load regulation and frequent thermal load fluctuations. Frequent cracking of header pipe seat fillet welds and fin tearing are common, seriously threatening the safe and stable operation of the units.

[0003] Therefore, it is particularly important to find an effective expansion pointer connection method to record the expansion state of the measured location. On the one hand, this ensures the stability and reliability of the expansion pointer connection structure, and on the other hand, it can accurately reflect the expansion state of the boiler header. Existing methods for connecting expansion pointers typically use simple snap-on or clamping connections. Due to the limitations of the header structure, the connection structure has a large extension length. The latter has a relatively complex shape, resulting in insufficient mechanical strength of the connection structure itself, and it cannot accurately reflect the expansion state of the header.

[0041] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation method, structure, characteristics and effects of the peak-shaving boiler header assembly proposed by the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0042] like Figure 1-3 As shown, an embodiment of the present invention provides a peak-shaving boiler header assembly, comprising:

[0043] header body(100);

[0044] At least one support member, the support member is connected to the header body (100), the support member includes at least three support ribs, and the at least three support ribs are arranged and connected in a triangular shape;

[0045] The support member (200) is used to connect the expansion pointer (200).

[0046] This embodiment can be applied to deep peak-shaving coal-fired power units with a capacity of 300MW or above, wherein the header body (100) can be a high-temperature header such as a furnace top superheater inlet and outlet header, a reheater inlet and outlet header, or an upper, middle, and lower water-cooled wall header, and the support member is used for connecting the expansion pointer (200) on the header body (100).

[0047] The expansion indicator indicates the expansion of the header body (100) by mechanical or electrical means. Common expansion indicators include an expansion pointer (200) and a dial. The expansion pointer (200) moves as the header body (100) expands, and through cooperation with the dial, indicates the size and direction of the expansion. In the prior art, there is a method of connecting the expansion pointer (200) to the pipe of the header body (100). However, due to the limitation of the structure of the header body (100), the extension of the clamping structure is usually very large, which makes the clamping structure itself easy to bend, lacks mechanical strength, and is also easily affected by hot installation and cold shrinkage. In the prior art, there is also a method of connecting the expansion pointer (200) to the header body (100) by welding, but this limits the location of the dial. In some locations, the dial cannot be placed, or the expansion monitoring of the location cannot be performed.

[0048] To solve the above problems, this embodiment adopts a support member (200) with a triangular arrangement of support ribs to achieve structural mutual restraint between the support ribs, thereby reducing the problem of heat deformation of the support ribs and the problem of deformation and vibration caused by long-term use, and increasing the stability of the connection structure. At the same time, through the extension of the support member (200), the expansion pointer (200) can be set at a position relatively far away from the header body (100) as needed, thereby providing conditions for the setting position of the dial, taking into account the diversity of compatible structures and the stability of the connection structure.

[0049] In some more specific embodiments, the header body (100) can be made of 12Cr1MoV alloy, which has high oxidation resistance and thermal strength. 12Cr1MoV alloy exhibits excellent oxidation resistance and thermal strength in high-temperature environments, can maintain high thermal strength and oxidation resistance at 580°C, and has high long-lasting plasticity. Good processing performance and weldability: 12Cr1MoV alloy has good processing performance. Through appropriate heat treatment processes such as normalizing and high-temperature tempering, ideal microstructure and mechanical properties can be obtained. Its welding performance is also good, but it needs to be preheated to 300°C before welding and stress relief treatment is required after welding.

[0050] The support ribs can be made of channel steel, which is economical and suitable, has good mechanical properties, and when rolled, the extension of each point on the cross section is relatively balanced, the internal stress is small, and the weight is light. While ensuring the structural strength, the volume of the support member (200) can be reduced. The number of support ribs can be only three, or it can be 4, 5, 6 or even more. At least three support ribs are directly arranged and connected in a triangular shape, which means that a triangular area is formed, and then a triangular support is formed. Depending on the specific connection position of the support member (200), the support member (200) can have a variety of structures. The following text will give examples of the implementation of the support member (200) in several specific positions.

[0051] The peak-shifting boiler header assembly provided by the embodiment of the present application can indicate the expansion state of the boiler header through the pointer under various complex structures, so that the abnormal expansion position can be found in time. The support member includes at least three support ribs, the at least three support ribs are arranged in connection in a triangular shape, the three or more support ribs assist each other, the measurement inaccuracy caused by the shape change of the support rib itself due to the heat deformation, vibration, long-term deformation and the like is reduced, the stability of the support member structure is ensured, and the expansion pointer can truly reflect the expansion displacement condition of the header.

[0052] In the first embodiment, as shown in Figure 1 The header body (100) includes a header main body (110), the header main body (110) includes a first end face, a second end face (111) and a cylindrical surrounding surface (112), the cylindrical surrounding surface (112) is located between the first end face and the second end face (111), and the first end face, the second end face (111) and the cylindrical surrounding surface (112) are enclosed to form the header main body (110). The support member includes an end face support member (300), at least one of the first end face and the second end face is connected with the end face support member (300), and the end face support member (300) is used to connect the expansion pointer (200).

[0053] That is, the header body (100) is approximately cylindrical, and the end face support member (300) can be connected to the second end face (111), and then the expansion displacement of the second end face (111) can be detected. Specifically, the end face support member (300) includes a first end face support rib (310), a second end face support rib (320), a third end face support rib (330), a fourth end face support rib (340), a fifth end face support rib (350), and a sixth end face support rib (360). The first end face support rib (310), the second end face support rib (320), and the third end face support rib (330) are arranged and connected in a triangular manner, the first end face support rib (310), the fourth end face support rib (340), and the fifth end face support rib (350) are arranged and connected in a triangular manner, and the first area of ​​the length direction of the third end face support rib (330), the fourth end face support rib (340), and the sixth end face support rib (360) are arranged and connected in a triangular manner. The second region of the sixth end surface support rib (360) in the longitudinal direction extends outside the region enclosed by the first region of the first end surface support rib (310), the second end surface support rib (320), the third end surface support rib (330), the fourth end surface support rib (340), the fifth end surface support rib (350) and the first region of the sixth end surface support rib (360), and the second region of the sixth end surface support rib (360) is used to connect the expansion pointer (200). That is, the first region of the first end surface support rib (310), the second end surface support rib (320), the third end surface support rib (330), the fourth end surface support rib (340), the fifth end surface support rib (350) and the first region of the sixth end surface support rib (360) are connected to form a triangular pyramid shape. The first end surface support rib (310), the fourth end surface support rib (340) and the fifth end surface support rib (350) are connected to the first end surface or the second end surface (111), such as by welding to the second end surface (111). The fourth end surface support rib (340) can be arranged in the first direction along the diameter of the second end surface (111). The fourth end surface support rib (340) does not necessarily have to be located entirely within the second end surface (111), and can also extend beyond the second end surface (111) at both ends. The first area of ​​the length direction of the second end surface support rib (320), the fifth end surface support rib (350), and the sixth end surface support rib (360) is triangular, and the sixth end surface support rib (360) is perpendicular to the second end surface (111). The second end surface support rib (320), the fifth end surface support rib (350), and the sixth end surface support rib (360) are all arranged in a direction perpendicular to the first direction. The expansion pointer (200) is arranged in the first direction, and then the sixth end surface support rib (360) is not easily deformed due to the action of other directly or indirectly connected support ribs, and can accurately reflect the expansion of the second end surface (111). Among them, the ratio of the first area to the second area of ​​the sixth end surface support rib (360) is not less than 1.

[0054] In the second embodiment, if Figure 1 As shown, the header body (100) includes a header body (110) and a pipe (120), and the pipe (120) is connected to and communicates with the header body (110). There are multiple pipes (120), such as Figure 1 The middle pipe (120) extends in a first direction and is arranged in parallel. The support member includes a pipe support member (400), the pipe support member (400) is connected to at least one pipe (120), and the pipe support member (400) is used to connect the expansion pointer (200).

[0055] In a more specific embodiment, the pipe support member (400) includes a first pipe support rib (410), a second pipe support rib (420), and a third pipe support rib (430). The first areas of the first pipe support rib (410), the second pipe support rib (420), and the third pipe support rib (430) are arranged and connected in a triangular shape, and the second area of ​​the third pipe support rib (430) extends outside the area enclosed by the first areas of the first pipe support rib (410), the second pipe support rib (420), and the third pipe support rib (430). The second area of ​​the third pipe support rib (430) is used to connect the expansion pointer (200). The first pipe support rib (410), the second pipe support rib (420), and the third pipe support rib (430) are connected to the pipe (120).

[0056] For example, the second pipe support rib (420) extends in the same direction as the pipe (120) and is welded to one of the multiple pipes (120). The third pipe support rib (430) is perpendicular to the extending direction of the pipe (120), while the first pipe support rib (410) is tilted. The expansion pointer (200) extends in the same direction as the pipe (120). The first pipe support rib (410) and the third pipe support rib (430) are structurally connected to the pipe (120) and extend to the outside of the area where the pipe (120) is located. The first pipe support rib (410) then supports the third pipe support rib (430), making the third pipe support rib (430) less prone to deformation and having high structural strength, thereby ensuring that the expansion of the pipe (120) area can be accurately reflected. The ratio of the first area to the second area of ​​the third pipe support rib (430) is not less than 1.

[0057] In the third embodiment, if Figure 2As shown, the header body (100) includes a header main body (110) and a connecting lug (130), the header main body (110) includes a first end face, a second end face (111) and a cylindrical surrounding surface (112), the cylindrical surrounding surface (112) is located between the first end face and the second end face (111), the first end face, the second end face (111) and the cylindrical surrounding surface (112) enclose the header main body (110), and the connecting lug (130) is connected to the cylindrical surrounding surface (112) and can extend perpendicularly to the axial direction of the header main body (110).

[0058] The support member includes an ear support member (500) connected to the connecting lug (130) and the cylindrical surrounding surface (112), and the ear support member (500) is used to connect the expansion pointer (200). By being connected to the connecting lug (130) and the cylindrical surrounding surface (112) at the same time, the stability of the position of the ear support member (500) is increased, and at the same time, by the structural arrangement of the ear support member (500) itself, the expansion state of the header main body (110) can be accurately reflected.

[0059] In a more specific embodiment, the ear support member (500) includes an ear support plate (510), a first ear support rib (520) and a second ear support rib (530). The ear support plate (510) includes a triangular area (511) and an extension rod area (512), the extension rod area (512) is connected to the front end corner point of the triangular area (511), the triangular area (511) includes a hollow (501) and can achieve the effect of reducing the weight of the triangular area (511). The side of the triangular area (511) away from the front end corner point is connected to the connecting lug (130), such as being welded, the triangular area (511) can be parallel to the axial direction of the header main body (110) and perpendicular to the extension direction of the connecting lug (130).

The end of the extension rod area (512) away from the triangular area (511) is used to connect the expansion pointer (200).

[0060] Then, by using the connecting lug (130), the structure stability of the extension rod area (512) is ensured by the structure of the triangular area (511) itself and the support of the second ear support rib (530), and the expansion state of the header main body (110) can be accurately reflected.

[0061] In a fourth embodiment, the header body (100) includes a header body (110) and a plurality of pipes (120), wherein the plurality of pipes (120) are all connected to and communicate with the header body (110).

All the pipelines (120) pass through the series plate (670). The extension frame is connected to one of the series plate (670) and all the pipelines (120). The extension frame is used to connect the expansion pointer (200). Then, the expansion displacement of any one or more of all the pipelines (120) can be reflected to the expansion pointer (200) through the series plate (670), and the extension is realized through the extension frame, thereby making the position of the expansion pointer (200) flexible.

The sixth extension rib (660) is connected to an end of the third extension rib (630) away from the first extension rib (610). The plane formed by the third extension rib (630), the fourth extension rib (640) and the fifth extension rib (650) is perpendicular to the plane formed by the second extension rib (620) and the first extension rib (610). The sixth extension rib (660) is perpendicular to the plane formed by the third extension rib (630), the fourth extension rib (640) and the fifth extension rib (650). The sixth extension rib (660) is connected to the expansion pointer (200). The extension direction of the expansion pointer (200) is perpendicular to the sixth extension rib (660) and perpendicular to the series plate (670).

[0065] The above arrangement achieves a stable support structure by vertically arranging the supporting ribs. The third extension rib (630), the fourth extension rib (640), and the fifth extension rib (650) are arranged to provide a flexible arrangement for avoiding obstacles. In some embodiments, the third extension rib (630), the fourth extension rib (640), and the fifth extension rib (650) may not be provided.

[0066] The above embodiments do not necessarily need to be used independently. For example, in some embodiments, the header body (100) can simultaneously have several or all of the end face support members (300), pipe support members (400), ear support members (500) and integrated support members (600) in the above embodiments, and then all-round expansion monitoring can be achieved through the expansion pointers (200) set at different positions.
