Description

Technical Field

[0001] The embodiments of the present disclosure relate to the field of combustion technology, and in particular to a hydrogen-cooled flame tube and a wall temperature control method applicable to a pure hydrogen gas turbine. Background Art

[0002] The high-intensity heat load caused by the high-temperature flame that the flame tube bears during the combustion process limits the improvement of gas turbine performance. Therefore, it is necessary to adopt a cooling design and reduce the flame tube wall temperature by exerting the cooling potential of the cooling medium. At present, when reducing the wall temperature of the flame tube, the commonly used methods are: cooling through pure gas film, impact and layer plate, or cooling the flame tube through a composite cooling method combining multiple cooling methods, which consumes more than 20% of the compressor outlet air volume; when cooling the flame tube, a pre-set fixed amount of air is directly flowed from the compressor outlet to the flame tube, and the flame tube is regularly inspected by naked eyes to determine whether the flame tube is damaged.

[0003] However, in practice, when the above method is used to cool the flame tube, the following technical problems often occur:

[0004] First, when the flame tube is cooled by the designed pure gas film, impact and layer plate, the airflow at the compressor outlet is more complicated, and the uniformity of the airflow is greatly affected by the structure and environment inside the combustion chamber, resulting in poor uniformity and stability of the flame tube cooling airflow, leading to poor uniformity and stability of the flame tube cooling; since the hydrogen gas turbine needs to use at least 70% of the compressor outlet air to organize combustion, there will not be enough air for cooling the flame tube, resulting in a higher temperature of the flame tube wall and a shortened life of the flame tube.

[0005] Second, a fixed amount of air flows directly to the flame tube instead of flowing to the flame tube through a set opening of a valve that controls the amount of air flowing to the flame tube. This makes it more difficult to adjust the amount of air flowing to the flame tube. When the wall temperature of the flame tube fluctuates greatly, it is more difficult to adjust the temperature of the flame tube with a fixed amount of air and the cooling effect is poor.

[0006] Third, the flame tube is only inspected regularly by the naked eye, which has low accuracy. Regular inspection of the flame tube for damage results in poor timeliness in detecting damage to the flame tube, a long repair cycle for the flame tube, and a shortened life of the flame tube.

[0007] The above information disclosed in this Background section is only for enhancement of understanding of the background of the inventive concept and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art.

The reasons for the poor stability and cooling effect of the flame tube cooling, the shortened flame tube life, and the greater difficulty of the flame tube cooling design are: when the flame tube is cooled by the designed pure gas film, impact, and layer plate, the airflow at the compressor outlet is relatively complex, and the uniformity of the airflow is greatly affected by the structure and environment inside the combustion chamber, resulting in poor uniformity and stability of the flame tube cooling airflow, resulting in poor uniformity and stability of the flame tube cooling; because the hydrogen gas turbine needs to use at least 70% of the compressor outlet air for organizing combustion, there will not be enough air for the cooling of the flame tube, resulting in a high temperature of the flame tube wall temperature and a shortened flame tube life. Based on this, some embodiments of the present disclosure are suitable for a hydrogen-cooled flame tube for a pure hydrogen gas turbine, characterized in that the hydrogen-cooled flame tube comprises an inner wall and an outer wall, wherein a cooling channel is formed between the inner wall and the outer wall, and the cooling medium of the hydrogen-cooled flame tube is hydrogen; at least two heat exchange ribs are arranged in the cooling channel, and the at least two heat exchange ribs are evenly arranged along the circumferential direction of the inner wall, and a microchannel is formed between every two adjacent heat exchange ribs of the at least two heat exchange ribs; a distribution cavity is arranged at the head end of the hydrogen-cooled flame tube, and at least one air inlet pipe is evenly arranged in the circumferential direction of the distribution cavity; an air collecting cavity is arranged at the end of the hydrogen-cooled flame tube, and at least one air outlet pipe is evenly arranged in the circumferential direction of the air collecting cavity; the hydrogen-cooled flame tube is provided with a mixing hole, and the mixing hole is connected to the inner wall and the outer wall to form a through channel. Also, because the hydrogen-cooled flame tube applicable to the pure hydrogen gas turbine is cooled by hydrogen as a cooling medium, rather than by the outlet air of the compressor, the low temperature and high thermal conductivity of hydrogen can improve the cooling effect on the flame tube. Also, because there is no need to design cooling structures such as pure gas film, impact and layer plates, the difficulty of flame tube cooling design can be reduced. Also, because the above-mentioned hydrogen cooling flame tube suitable for pure hydrogen gas turbines includes an air collecting chamber and an air inlet pipe, hydrogen can enter the air collecting chamber through the air inlet pipe of the above-mentioned hydrogen cooling flame tube suitable for pure hydrogen gas turbines, and then pass through the air collecting chamber to enter the microchannel. The flow velocity of hydrogen in the microchannel is relatively high, and the heat exchange ribs included in the above-mentioned hydrogen cooling flame tube suitable for pure hydrogen gas turbines increase the heat exchange area, so that the hydrogen in the microchannel can be disturbed, thereby improving the heat exchange efficiency of the above-mentioned hydrogen cooling flame tube suitable for pure hydrogen gas turbines, and the heat exchange ribs are evenly distributed along the inner wall of the above-mentioned hydrogen cooling flame tube suitable for pure hydrogen gas turbines, thereby improving the uniformity of the flame tube temperature distribution.Thereby, the stability and cooling effect of the flame tube cooling can be improved, the flame tube life can be extended, and the difficulty of the flame tube cooling design can be reduced.

Figure 1 It comprises an inner wall 1, an outer wall 2, an air inlet pipe 3, an air outlet pipe 4, at least two heat exchange ribs 5 and a mixing hole 6.

[0033] Figure 2 4 is a cross-sectional view of a hydrogen-cooled flame tube suitable for a pure hydrogen gas turbine according to an embodiment of the present invention. Figure 2 It includes an air inlet pipe 3 , an air outlet pipe 4 , a distribution chamber 21 and an air collecting chamber 22 .

[0034] Figure 3 It is a partially enlarged schematic diagram of a hydrogen-cooled flame tube suitable for a pure hydrogen gas turbine according to an embodiment of the present invention. Figure 3 It includes an inner wall 1 , an outer wall 2 , an air inlet pipe 3 , a mixing hole 6 , a distribution cavity 21 , a microchannel 23 and at least one test channel 24 .

[0035] In some embodiments, Figure 1 and Figure 2 As shown, a cooling channel can be formed between the inner wall 1 and the outer wall 2. The cooling medium of the hydrogen cooling flame tube can be hydrogen. A distribution chamber 21 is provided at the head end of the hydrogen cooling flame tube. At least one air inlet pipe 3 is evenly arranged in the circumferential direction of the distribution chamber 21. A gas collecting chamber 22 is provided at the end of the hydrogen cooling flame tube. At least one air outlet pipe 4 is evenly arranged in the circumferential direction of the gas collecting chamber 22. The hydrogen cooling flame tube is provided with a mixing hole 6. The mixing hole 6 is connected to the inner wall 1 and the outer wall 2. A cooling channel is formed between the inner wall 1 and the outer wall 2. At least two heat exchange ribs 5 are arranged in the cooling channel. The at least two heat exchange ribs 5 are evenly arranged along the circumferential direction of the inner wall 1. The inner wall 1 can be a high temperature resistant ceramic material. The outer wall 2 can be a high temperature resistant alloy material. Here, the material of the inner wall 1 and the outer wall 2 is not specifically limited.

[0036] In some embodiments, Figure 1 and Figure 3 As shown, at least two heat exchange ribs 5 may be arranged in the cooling channel. The at least two heat exchange ribs 5 may be evenly arranged along the circumferential direction of the inner wall 1. A microchannel 23 may be formed between every two adjacent heat exchange ribs 5 of the at least two heat exchange ribs 5. Since the distance between every two adjacent heat exchange ribs 5 of the at least two heat exchange ribs 5 is small, the channel formed between every two adjacent heat exchange ribs 5 is narrow, so that the channel formed between every two adjacent heat exchange ribs 5 is a microchannel.

[0037] In some embodiments, Figure 2 As shown, the head end of the hydrogen cooling flame tube may be provided with a distribution chamber 21. At least one intake pipe 3 may be evenly arranged in the circumferential direction of the distribution chamber 21. The distribution chamber 21 may be used to store and distribute the hydrogen entering the intake pipe 3.

[0038] In some embodiments, Figure 2 As shown, a gas collecting cavity 22 may be provided at the end of the hydrogen cooling flame tube, and at least one gas outlet pipe 4 may be evenly provided in the circumferential direction of the gas collecting cavity 22. The gas collecting cavity 22 may be used to collect the hydrogen to be discharged after heat exchange.

[0039] In some embodiments, Figure 1 As shown, the hydrogen cooling flame tube may be provided with a mixing hole 6. The mixing hole 6 and the inner wall 1 may be connected to the outer wall 2 to form a through channel. The mixing hole 6 may be a hole for injecting cooling gas to adjust the temperature distribution of the combustion chamber and the wall temperature of the cooling flame tube. The air inlet pipe 3 may be a pipe for cooling gas to enter the hydrogen cooling flame tube. The air outlet pipe 4 may be a pipe for discharging the gas in the hydrogen cooling flame tube. The cooling medium of the hydrogen cooling flame tube may be hydrogen. Hydrogen has the characteristics of low temperature and high thermal conductivity. Therefore, using hydrogen as a cooling medium has a better cooling effect on the hydrogen cooling flame tube. The heat exchange ribs 5 may increase the heat exchange area.

[0040] Alternatively, if Figure 1 As shown, the width of each of the at least two heat exchange ribs 5 can range from 1.4 mm to 1.6 mm, and the height can range from 0.9 mm to 1.1 mm. Here, the specific values ​​of the width and height of each of the at least two heat exchange ribs 5 are not specifically limited. The material of each of the at least two heat exchange ribs 5 can be a high temperature resistant alloy material. Here, the material of the heat exchange ribs is not specifically limited.

[0041] Alternatively, if Figure 1As shown, the thickness of the inner wall 1 may range from 1.4 mm to 1.6 mm, and the thickness of the outer wall 2 may range from 1.9 mm to 2.1 mm. Here, the specific values ​​of the thickness of the inner wall and the thickness of the outer wall are not specifically limited.

[0042] Alternatively, if Figure 1 As shown, the above-mentioned hydrogen cooling flame tube is prepared by an integral molding method.

[0043] Alternatively, if Figure 3 As shown, the hydrogen cooling flame tube may include at least one test channel 24. The at least one test channel 24 may penetrate the outer wall 2 and one of the at least two heat exchange ribs 5.

[0044] Alternatively, if Figure 3 As shown, the hydrogen cooling flame tube may include a preset number of temperature sensors. The head end of each of the preset number of temperature sensors may be plugged into the test channel 24 in the at least one test channel 24. The end of each of the preset number of temperature sensors may be connected to a signal processor. The preset number may be 4. The test channel 24 in the at least one test channel 24 may be used to plug in a temperature sensor to measure the wall temperature of the hydrogen cooling flame tube. The preset number of temperature sensors are located at different positions, so the wall temperature at different positions of the hydrogen cooling flame tube may be detected.

[0045] It should be noted that the process of cooling the above-mentioned hydrogen-cooled flame tube by hydrogen is as follows: first, hydrogen can enter the above-mentioned distribution chamber 21 through the above-mentioned air inlet pipe 3. Then the above-mentioned distribution chamber 21 can disperse the hydrogen to the microchannel 23. After that, the hydrogen can enter the gas collecting chamber 22 after heat exchange in the above-mentioned microchannel 23, and finally, the hydrogen after heat exchange can be discharged through the above-mentioned outlet pipe 4. The heat exchange ribs 5 on both sides of the microchannel 23 increase the heat exchange area and form disturbances to the hydrogen, and the microchannel 23 is narrow, so the hydrogen can flow at a high speed in the above-mentioned microchannel 23, thereby improving the heat exchange efficiency, and the above-mentioned at least two heat exchange ribs 5 are evenly arranged along the circumferential direction of the above-mentioned inner wall 1, thereby improving the temperature uniformity of the above-mentioned hydrogen-cooled flame tube.

[0046] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the hydrogen-cooled flame tube applicable to pure hydrogen gas turbines of some embodiments of the present disclosure, the stability and cooling effect of the flame tube cooling can be improved, the flame tube life can be extended, and the difficulty of the flame tube cooling design can be reduced. The reasons for the poor stability and cooling effect of the flame tube cooling, the shortened flame tube life, and the greater difficulty of the flame tube cooling design are: when the flame tube is cooled by the designed pure gas film, impact, and layer plate, the airflow at the compressor outlet is relatively complex, and the uniformity of the airflow is greatly affected by the structure and environment inside the combustion chamber, resulting in poor uniformity and stability of the flame tube cooling airflow, resulting in poor uniformity and stability of the flame tube cooling; because the hydrogen gas turbine needs to use at least 70% of the compressor outlet air for organizing combustion, there will not be enough air for the cooling of the flame tube, resulting in a high temperature of the flame tube wall temperature and a shortened flame tube life. Based on this, some embodiments of the present disclosure are suitable for a hydrogen-cooled flame tube for a pure hydrogen gas turbine, characterized in that the hydrogen-cooled flame tube comprises an inner wall and an outer wall, wherein a cooling channel is formed between the inner wall and the outer wall, and the cooling medium of the hydrogen-cooled flame tube is hydrogen; at least two heat exchange ribs are arranged in the cooling channel, and the at least two heat exchange ribs are evenly arranged along the circumferential direction of the inner wall, and a microchannel is formed between every two adjacent heat exchange ribs of the at least two heat exchange ribs; a distribution cavity is arranged at the head end of the hydrogen-cooled flame tube, and at least one air inlet pipe is evenly arranged in the circumferential direction of the distribution cavity; an air collecting cavity is arranged at the end of the hydrogen-cooled flame tube, and at least one air outlet pipe is evenly arranged in the circumferential direction of the air collecting cavity; the hydrogen-cooled flame tube is provided with a mixing hole, and the mixing hole is connected to the inner wall and the outer wall to form a through channel. Also, because the hydrogen-cooled flame tube applicable to the pure hydrogen gas turbine is cooled by hydrogen as a cooling medium, rather than by the outlet air of the compressor, the low temperature and high thermal conductivity of hydrogen can improve the cooling effect on the flame tube. Also, because there is no need to design cooling structures such as pure gas film, impact and layer plates, the difficulty of flame tube cooling design can be reduced. Also, because the above-mentioned hydrogen cooling flame tube suitable for pure hydrogen gas turbines includes an air collecting chamber and an air inlet pipe, hydrogen can enter the air collecting chamber through the air inlet pipe of the above-mentioned hydrogen cooling flame tube suitable for pure hydrogen gas turbines, and then pass through the air collecting chamber to enter the microchannel. The flow velocity of hydrogen in the microchannel is relatively high, and the heat exchange ribs included in the above-mentioned hydrogen cooling flame tube suitable for pure hydrogen gas turbines increase the heat exchange area, so that the hydrogen in the microchannel can be disturbed, thereby improving the heat exchange efficiency of the above-mentioned hydrogen cooling flame tube suitable for pure hydrogen gas turbines, and the heat exchange ribs are evenly distributed along the inner wall of the above-mentioned hydrogen cooling flame tube suitable for pure hydrogen gas turbines, thereby improving the uniformity of the flame tube temperature distribution.Thereby, the stability and cooling effect of the flame tube cooling can be improved, the flame tube life can be extended, and the difficulty of the flame tube cooling design can be reduced.

[0047] Further references Figure 4 , Figure 4 The process 400 of some embodiments of the wall temperature control method of the hydrogen-cooled flame tube of a pure hydrogen gas turbine according to the present disclosure is shown. The wall temperature control method of the hydrogen-cooled flame tube of a pure hydrogen gas turbine includes the following steps:

[0048] Step 401, in response to receiving each real-time temperature information of the target flame tube sent by the target signal processor, generating dispersion information and average temperature information corresponding to each real-time temperature information according to each real-time temperature information.

[0049] In some embodiments, in response to receiving each real-time temperature information of the target flame tube sent by the target signal processor, the execution subject (e.g., computing device) of the wall temperature control method of the hydrogen-cooled flame tube of the pure hydrogen gas turbine can generate dispersion information and average temperature information corresponding to each real-time temperature information according to the above-mentioned real-time temperature information. Figure 1 The described is suitable for a hydrogen-cooled flame tube of a pure hydrogen gas turbine. Each of the above-mentioned real-time temperature information may be detected by a preset number of temperature sensors plugged into the above-mentioned target flame tube. The above-mentioned target signal processor may be an information processor connected to the above-mentioned preset number of temperature sensors. The above-mentioned signal processor may be used to receive temperature data detected by the above-mentioned preset number of temperature sensors and send the received temperature data to a terminal. The real-time temperature information in the above-mentioned each of the real-time temperature information may correspond to a temperature sensor in the above-mentioned preset number of temperature sensors. The above-mentioned preset number may be 4. The real-time temperature information in the above-mentioned each of the real-time temperature information may be the flame tube wall temperature at the current moment detected by the temperature sensor. The above-mentioned average temperature information may represent the average value of the above-mentioned each of the real-time temperature information. The above-mentioned dispersion information may represent the dispersion of the above-mentioned each of the real-time temperature information.

[0050] In some optional implementations of some embodiments, the execution subject may generate dispersion information and average temperature information corresponding to each of the real-time temperature information according to the real-time temperature information through the following steps:

[0051] The first step is to determine the average temperature information corresponding to each of the real-time temperature information according to the above-mentioned real-time temperature information. In practice, the above-mentioned execution subject may determine the average value of each of the real-time temperature information as the average temperature information.

[0052] In the second step, the difference between the real-time temperature information that meets the preset temperature condition and the average temperature information is determined as the dispersion information corresponding to each of the real-time temperature information. The preset temperature condition may be the maximum value among the real-time temperature information. In practice, the execution subject may determine the difference between the maximum value and the dispersion represented by the dispersion information as the dispersion information.

[0053] Step 402: Determine the control ratio information corresponding to the original flow control valve opening information according to the dispersion information and the average temperature information.

[0054] In some embodiments, the execution subject may determine the control ratio information corresponding to the original flow control valve opening information according to the dispersion information and the average temperature information. The original flow control valve opening information may be the opening of the flow control valve assembly that controls the hydrogen entering the target flame tube. The control ratio information may represent the ratio of the opening represented by the original flow control valve opening information.

[0055] In some optional implementations of some embodiments, the execution subject may determine the control ratio information corresponding to the original flow control valve opening information according to the dispersion information and the average temperature information through the following steps:

[0056] In the first step, in response to determining that the dispersion information is greater than the preset deviation value information, the first preset ratio information is determined as the control ratio information. The preset deviation value information may represent a deviation value. The preset deviation value information may be 20°C. The first preset ratio information may be a ratio of changing the opening represented by the original flow control valve opening information. The first preset ratio information may be 2%.

[0057] In the second step, in response to determining that the dispersion information is less than or equal to the preset deviation value information, determine whether the average temperature information is greater than a preset high setting value, wherein the preset high setting value may be 700°C.

[0058] In a third step, in response to determining that the average temperature information is greater than the preset high setting value, the first preset proportion information is determined as the control proportion information.

[0059] In step 4, in response to determining that the average temperature information is less than or equal to the preset high setting value, determine whether the average temperature information is less than a preset low setting value. The preset low setting value may be 400°C.

[0060] Step 5: In response to determining that the average temperature information is less than the preset low setting value, determine the second preset ratio information as the control ratio information. The second preset ratio information may be 1%.

[0061] Step 403: update the original flow control valve opening information according to the control ratio information to obtain the changed flow control valve opening information.

[0062] In some embodiments, the execution subject may update the original flow control valve opening information according to the control ratio information to obtain the changed flow control valve opening information. The changed flow control valve opening information may represent the updated original flow control valve opening information. In practice, first, in response to determining that the control ratio information is the first preset ratio information, the execution subject may determine the product of the first preset ratio information and the original flow control valve opening information as the target opening. Then, the sum of the original flow control valve opening information and the target opening is determined as the changed flow control valve opening information. Afterwards, in response to determining that the control ratio information is the second preset ratio information, the execution subject may determine the product of the second preset ratio information and the original flow control valve opening information as the target opening. Then, the difference between the original flow control valve opening information and the target opening is determined as the changed flow control valve opening information.

[0063] Optionally, after step 403, in response to determining that the dispersion information is less than or equal to the preset deviation value information and the average temperature information satisfies a preset average temperature condition, the execution subject may determine the original flow control valve opening information as the changed flow control valve opening information. The preset average temperature condition may be that the average temperature information is greater than the preset low setting value and less than the preset high setting value.

[0064] Step 404, obtaining detailed information of each historical flow rate corresponding to the target flame tube.

[0065] In some embodiments, the execution subject can obtain each historical flow detail information corresponding to the target flame tube. The historical flow detail information in each historical flow detail information includes temperature information at each historical moment, position information of the preset number of temperature sensors and opening information of each flow control valve. The temperature information at each historical moment in the temperature information can represent the temperature at the historical moment. For example, the temperature information at the historical moment can represent the temperature at 17 o'clock. The position information of the preset number of temperature sensors can represent each position of the preset number of temperature sensors at the target flame tube. The flow control valve opening information in each flow control valve opening information can represent the opening of the flow control valve. In practice, the execution subject can obtain each historical flow detail information of the target flame tube from a database storing each historical flow detail information.

[0066] Step 405, generating predicted flow control valve opening information corresponding to the target flame tube according to each historical flow detail information.

[0067] In some embodiments, the execution subject may generate predicted flow control valve opening information corresponding to the target flame tube according to the historical flow details information, wherein the predicted flow control valve opening information may represent the predicted opening of the flow control valve of the target flame tube.

[0068] In some optional implementations of some embodiments, the execution subject may generate the predicted flow control valve opening information corresponding to the target flame tube according to the historical flow details information through the following steps:

[0069] The first step is to divide and process the above-mentioned various historical flow details information according to the preset division ratio information to obtain the first historical flow details information group and the second historical flow details information group. Among them, the above-mentioned preset division ratio information can represent the division ratio corresponding to the above-mentioned various historical flow details information. The above-mentioned preset division ratio information can be 70%. In practice, firstly, the above-mentioned execution entity can determine the product of the above-mentioned preset division ratio information and the number of the above-mentioned various historical flow details information as the target number. Then, the above-mentioned target number of historical flow details information is determined as the first historical flow details information group. Finally, the remaining historical flow details information in the above-mentioned various historical flow details information is determined as the second historical flow details information group.

[0070] The second step is to obtain the target time temperature information corresponding to the target flame tube, wherein the target time temperature information can represent the temperature information of the target flame tube at the current time.

[0071] In the third step, the target time period temperature information and the position information of the preset number of temperature sensors are input into the variable information input layer in the pre-trained prediction flow control valve opening information generation model to obtain the first characteristic variable information and the second characteristic variable information. Among them, the prediction flow control valve opening information generation model can be a neural network model based on variable selection and sparse self-attention mechanism, which takes the target time period temperature information and the position information of the preset number of temperature sensors as input and the prediction flow control valve opening information as output. The first characteristic variable information can characterize the variable characteristics of the temperature information at the target moment. The second characteristic variable information can characterize the variable characteristics of the position information of the preset number of temperature sensors. The prediction flow control valve opening information generation model can include a variable information selection layer, a variable information encoding layer and a data processing layer, a sparse attention layer and a gated feedforward layer. Among them, the prediction flow control valve opening information generation model can be trained by the following steps: First, the execution subject can divide the acquired historical flow details information according to the preset division ratio information to obtain the first historical flow details information group and the second historical flow details information group. Then, the initial predicted flow control valve opening information generation model is trained according to the obtained first historical flow detail information group and the second historical flow detail information group. Finally, the trained initial predicted flow control valve opening information generation model is used as the predicted flow control valve opening information generation model.

[0072] In the fourth step, the first characteristic variable information and the second characteristic variable information are input into the variable information selection layer in the prediction flow control valve opening information generation model to obtain the first variable selection information and the second variable selection information. The first variable selection information can characterize the characteristics of each variable selected from the first characteristic variable information. The second variable selection information can characterize the characteristics of each variable selected from the second characteristic variable information. The variable information selection layer can be used to select variable characteristics from the first characteristic variable information and the second characteristic variable information. The variable information selection layer can include a gated feedforward network GFFN. The gated recurrent unit of the GFFN can be a GRU.

[0073] The fifth step is to input the first variable selection information and the second variable selection information into the variable information encoding layer in the prediction flow control valve opening information generation model to obtain fused coding feature information. The fused coding feature information can characterize the features of the first variable selection information and the second variable selection information. The variable information encoding layer may include a first encoder and a second encoder. Both the first encoder and the second encoder may be sparse encoders. In practice, the execution subject may input the first variable selection information and the second variable selection information into the first encoder to obtain a first output result. Then, the first output result is input into the second encoder to obtain fused coding feature information.

[0074] In the sixth step, the fused coding feature information and the second variable selection information are input into the data processing layer in the prediction flow control valve opening information generation model to obtain fused coding processing information. The data processing layer can be used to extract features from the fused coding feature information and the second variable selection information. The data processing layer can be a gated feedforward network GFFN. The fused coding processing information can characterize the features of the extracted fused coding feature information and the second variable selection information.

[0075] In the seventh step, the fused coding information is input into the sparse attention layer in the prediction flow control valve opening information generation model to obtain fused feature information. The sparse attention layer can be used to perform sparse attention processing and residual connection processing on the fused coding information. The fused feature information can represent the feature representation of the fused coding information.

[0076] In the eighth step, the fused feature information is input into the gated feedforward layer in the predicted flow control valve opening information generation model to obtain the predicted flow control valve opening information corresponding to the target flame tube.

[0077] Step 406, generating flow control valve opening information corresponding to the target flame tube according to the predicted flow control valve opening information and the changed flow control valve opening information.

[0078] In some embodiments, the flow control valve opening information corresponding to the target flame tube can be generated according to the predicted flow control valve opening information and the changed flow control valve opening information. In practice, the execution subject can determine the average value of the predicted flow control valve opening information and the changed flow control valve opening information as the flow control valve opening information.

[0079] The above technical solution, as an inventive point of an embodiment of the present disclosure, solves the second technical problem mentioned in the background technology, "directly flowing a fixed amount of air to the flame tube, instead of flowing the air to the flame tube by setting the opening of the valve that controls the air flow to the flame tube, makes it difficult to adjust the air flow to the flame tube. When the wall temperature of the flame tube fluctuates greatly, it is difficult to adjust the temperature of the flame tube with a fixed amount of air, and the cooling effect is poor." The reason for the poor cooling effect of the flame tube is that a fixed amount of air is directly flowing to the flame tube, instead of flowing the air to the flame tube by setting the opening of the valve that controls the air flow to the flame tube. If the above factors are solved, the effect of cooling the flame tube can be improved. In order to achieve this effect, the present disclosure adjusts the flow of the cooling medium entering the flame tube by generating the valve opening of the flow control valve assembly. When generating the valve opening of the flow control valve assembly, first, the change flow control valve opening information of the flame tube is determined by the average temperature and dispersion. Then, the predicted flow control valve opening information is generated by the trained predicted flow control valve opening information generation model. Afterwards, the flow control valve opening information of the flame tube is jointly generated by predicting the flow control valve opening information and the obtained changed flow control valve opening information, thereby improving the comprehensiveness of the generated flow control valve opening information and further improving the accuracy of the generated flame tube opening. Therefore, the hydrogen flow entering the flame tube can be more flexibly controlled according to the flow control valve opening information with higher accuracy.

[0080] Step 407, regulating the wall temperature of the target flame tube according to the flow control valve opening information.

[0081] In some embodiments, the execution entity may regulate the wall temperature of the target flame tube according to the flow control valve opening information.

[0082] Optionally, after step 407, the execution entity may further perform the following steps:

[0083] First, image information of the target flame tube is obtained, wherein the image information may represent an image of the target flame tube taken in real time.

[0084] Then, the image information is initialized to obtain the initialized image information. In practice, the execution subject may perform normalization on the image information by a normalization method to obtain the normalized image information as the initialized image information. For example, the normalization method may be a minimum-maximum normalization method.

[0085] Afterwards, the image information after the initialization processing is detected and processed to obtain the inclination information and crack information corresponding to the target flame tube. Among them, the inclination information can represent the inclination of the target flame tube. The crack information can be information representing whether there is a crack in the target flame tube. The crack information can be a rectangular box representing the existence of cracks in the image information or representing that there is no crack in the image information. When the crack information is empty, it represents that there is no crack in the image information. When the crack information is a rectangular box, the rectangular box represents the position of the crack in the image information. In practice, first, the execution subject can perform edge detection processing on the image information after the initialization processing by an edge detection algorithm to obtain the edge information of the target flame tube in the image information. For example, the edge detection algorithm can be Canny. Then, the edge information can be processed by a straight line fitting method to obtain the inclination corresponding to the target flame tube. Afterwards, the image information can be input into the crack information detection model to obtain the crack information corresponding to the target flame tube. The above crack information detection model may be a model that takes image information as input and crack information as output. The above crack information detection model may be a YOlOv3 model.

[0086] Secondly, in response to determining that the inclination information of the target flame tube meets the preset inclination condition, the first warning information corresponding to the target flame tube is determined according to the preset warning level information set. The preset warning level information set may include preset warning level information that characterizes the correspondence between the warning level and the inclination. For example, the preset warning level information may be: "Inclination: 50°, warning level: Level 1 warning". In practice, the execution entity may determine the preset warning level information included in the preset warning level information set, which has the same inclination as the inclination information of the target flame tube, as the first warning information corresponding to the target flame tube.

[0087] Then, in response to determining that the crack information of the target flame tube meets the preset crack condition, the second warning information corresponding to the crack information of the target flame tube is determined according to the preset warning level information set. Among them, the preset warning level information set may include preset warning level information that characterizes the correspondence between the warning level and the number of cracks represented by the crack information. For example, the preset warning level information may be: "Number of cracks: 5, warning level: Level 1 warning". In practice, the execution entity may determine the preset warning level information in the preset warning level information set, which has the same number of cracks as the number of cracks represented by the crack information of the target flame tube, as the second warning information corresponding to the target flame tube.

[0088] Secondly, the first warning information and the second warning information are determined as the warning information corresponding to the target flame tube.

[0089] Finally, the warning information is sent to a terminal device that monitors the target flame tube. For example, the terminal device may be a computer.

[0090] The above technical solution, as an inventive point of an embodiment of the present disclosure, solves the technical problem three mentioned in the background technology, "only the flame tube is regularly inspected by the naked eye, the accuracy of the naked eye detection of the flame tube is low, and the flame tube is regularly inspected for damage, resulting in poor timeliness in detecting the damage of the flame tube, a long period of repairing the flame tube, and shortening the life of the flame tube". The reasons for the long period of repairing the flame tube and the shortening of the life of the flame tube are that the flame tube is regularly inspected by the naked eye, the accuracy of the naked eye detection of the flame tube is low, and the flame tube is regularly inspected for damage. If the above factors are solved, the period of repairing the flame tube can be shortened and the shortening of the life of the flame tube can be reduced. In order to achieve this effect, when the flame tube is inspected, the present disclosure takes an image of the flame tube in real time, and then detects the inclination and cracks of the flame tube through the edge detection method and the pre-trained crack information detection model, and generates early warning information for the flame tube through the detected information, and sends the obtained early warning information to the terminal device. Therefore, when the flame tube is tilted or cracked, an early warning can be given to the flame tube in time to improve the timeliness of detecting damage to the flame tube, shorten the repair cycle of the flame tube, and reduce the situation of shortening the life of the flame tube.

[0091] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the wall temperature control method of the hydrogen-cooled flame tube of the pure hydrogen gas turbine according to some embodiments of the present disclosure, the flow rate of the cooling medium entering the hydrogen-cooled flame tube can be adjusted by the generated flow control valve opening information, thereby adjusting the wall temperature of the hydrogen-cooled flame tube and improving the cooling effect of the hydrogen-cooled flame tube. Specifically, the reason for the poor cooling effect of the hydrogen-cooled flame tube is that a fixed amount of air is directly flowed to the flame tube, rather than the air is flowed to the flame tube by setting the opening of the valve that controls the amount of air flowing to the flame tube, which makes it more difficult to adjust the amount of air flowing to the flame tube. When the temperature of the flame tube fluctuates greatly, it is more difficult to adjust the wall temperature of the flame tube with a fixed amount of air, and the cooling effect is poor. Based on this, in some embodiments of the present disclosure, a wall temperature control method for a hydrogen-cooled flame tube of a pure hydrogen gas turbine is provided. First, in response to receiving each real-time temperature information of a target flame tube sent by a target signal processor, dispersion information and average temperature information corresponding to each real-time temperature information are generated according to the above-mentioned each real-time temperature information, wherein the above-mentioned target flame tube is Figure 1The hydrogen-cooled flame tube suitable for pure hydrogen gas turbine described, the above-mentioned real-time temperature information is detected by a preset number of temperature sensors plugged into the above-mentioned target flame tube; the above-mentioned target signal processor is a signal processor connected to the above-mentioned preset number of temperature sensors. Thus, the dispersion and average temperature of the flame tube can be obtained. Then, according to the above-mentioned dispersion information and the above-mentioned average temperature information, the control ratio information corresponding to the original flow control valve opening information is determined. Thus, the original flow control valve opening information can be adjusted according to the control ratio. Secondly, according to the above-mentioned control ratio information, the above-mentioned original flow control valve opening information is updated and processed to obtain the changed flow control valve opening information. Thus, the flow control valve opening information of the corresponding flame tube generated according to the temperature information and the dispersion information can be obtained. Then, the various historical flow details information corresponding to the above-mentioned target flame tube is obtained. Thus, the historical details of the flame tube can be obtained, which can be used to predict the flow control valve opening information of the flame tube. Afterwards, according to the above-mentioned various historical flow details information, the predicted flow control valve opening information corresponding to the above-mentioned target flame tube is generated. Thus, the predicted flow control valve opening information can be obtained. Next, the flow control valve opening information corresponding to the target flame tube is generated according to the predicted flow control valve opening information and the changed flow control valve opening information. Thus, the final flow control valve opening information can be generated according to the predicted flow control valve opening information and the flow control valve opening information obtained according to the temperature information and the dispersion information. Finally, the wall temperature of the target flame tube is regulated according to the flow control valve opening information. Thus, the wall temperature of the target flame tube can be regulated. Also, the wall temperature of the flame tube is not regulated according to a fixed amount of cooling air, but the wall temperature of the flame tube is regulated by controlling the flow rate of hydrogen entering the flame tube according to the flow control valve opening information. Therefore, when the wall temperature of the flame tube fluctuates greatly, the wall temperature of the flame tube can be flexibly adjusted. And the flow control valve opening information is not only generated according to the temperature information and the dispersion, but also refers to the detailed information of each historical flow of the flame tube, thereby improving the accuracy of the generated flow control valve opening information, and further improving the effect of regulating the wall temperature of the flame tube.
