[0002] In large-capacity power station boilers, fly ash will follow the flue gas into the heating surface at the rear of the boiler. Due to the high hardness of fly ash, when it touches the heating surface tube row, it will cut off the tiny metal pieces on the outermost layer of the heating surface tube wall under the action of tangential force, which is easy to cause wear of the heating surface tube material, resulting in the tube wall of the heating surface tube becoming thinner and thinner, which is easy to cause leakage or tube burst accidents, affecting the safe operation of the boiler.

[0026] Embodiment 1

[0027] Figure 1 A flow chart of a method for correcting the anti-wear coefficient of pipe wall thickness is provided for the first embodiment of the present invention. This embodiment is applicable to the case where the anti-wear coefficient of the wall thickness of the heating surface pipe is corrected. The method can be executed by a pipe wall thickness anti-wear coefficient correction device. The pipe wall thickness anti-wear coefficient correction device can be implemented in the form of hardware and / or software. The pipe wall thickness anti-wear coefficient correction device can be configured in an electronic device. Figure 1 As shown, the method includes:

[0028] S110, obtaining current characteristic parameters of the heating surface pipe in the current cycle, as well as the wall thickness anti-wear coefficient determined in the historical cycle of the current cycle and the wall thickness wear value in the historical cycle.

[0029] The heating surface pipes may be the tail heating surface pipes of a power station boiler. During the operation of the power station boiler, fly ash easily enters the tail heating surface of the boiler along with the flue gas, causing the fine particles in the fly ash to wear the heating surface pipes, thereby causing the pipes to become thinner.

[0030] The current characteristic parameters may be characteristic parameters of the heating surface pipes in the current time period, wherein the characteristic parameters of the heating surface pipes may include the initial value of the wall thickness of the heating surface pipes, pipe diameter, pipe pitch, pipe arrangement structure, flue gas temperature, flue gas volume, fly ash concentration, pipe material, and pipe replacement time.

[0031] Among them, the initial value of the wall thickness of the location of the heating surface pipe can be the initial wall thickness value before the pipe is put into use. The pipe arrangement sequence can include a sequential structure and a staggered structure. The wear of pipes arranged in the sequential structure and the staggered structure is different. For the sequential structure of the pipe row, the wear law of the heating surface pipe is characterized by the first row of pipes on the heating surface being more severely worn. For the staggered arrangement of the pipe row, the wear law of the heating surface pipe is characterized by the second row of pipes on the heating surface being more severely worn.

[0032] Among them, flue gas temperature, flue gas volume and fly ash concentration are related to the amount of coal burned by the boiler and the power generation of the generator set, and are specifically directly proportional to the amount of coal burned by the boiler and the power generation of the generator set. The pipe diameter, pipe pitch and pipe material are the inherent properties of the pipe and are not affected by other changing factors. The pipe replacement time can be the time from the time the pipe is put into use to the time it ends.

[0033] The historical period of the current cycle may be an adjacent historical period corresponding to the current cycle. For example, if the preset time period is 1 year, and if the current period is 2021 / 01-2021 / 12, the historical period may be 2020 / 01-2020 / 12. The wall thickness wear resistance coefficient is used to characterize the wall thickness wear resistance of the heating surface pipe, which is specifically related to the characteristic parameters of the pipe. The wall thickness wear value may be the wear value obtained by comparing the heating surface pipe with the initial wall thickness value within the preset time period, that is, the actual wall thickness value of the pipe in the current period may be obtained by the initial wall thickness value of the pipe and the wall thickness wear value of the pipe.

[0034] Characteristic data, wall thickness wear values ​​and wall thickness anti-wear coefficients of heating surface pipes in historical periods can be stored in advance, and the data stored in historical periods can be obtained in the current period.

[0035] S120. Determine the wall thickness wear value of the heating surface pipe in the current cycle according to the current characteristic parameters and the wall thickness anti-wear coefficient in the historical cycle.

[0036] According to the current characteristic parameters and the wall thickness anti-wear coefficient in the historical cycle, based on the preset wall thickness wear value determination model, the wall thickness wear value of the heating surface pipe in the current cycle can be determined. Among them, the wall thickness wear value determination model can be pre-set by relevant technical personnel based on the correlation between the characteristic parameters of the heating surface pipe and the wall thickness wear value. The wall thickness wear value determination model can be as follows:

[0037] m=c km v 3 t;

[0038] Where m is the wall thickness wear value, c km is the wall thickness anti-wear coefficient under the historical period, v is the flue gas flow rate, and t is the pipe replacement time.

[0039] Among them, the flue gas velocity is related to characteristic parameters such as flue gas volume, pipe diameter and pipe pitch. The flue gas velocity will show irregular peaks and valleys in the heating surface as a whole. The peaks are where there are gaps between the pipes, and the corresponding flue gas velocity is higher; the valleys are where the pipes are, and the corresponding flue gas velocity is low. The wall thickness anti-wear coefficient under the historical cycle can be directly obtained from the characteristic parameters of the heating surface pipes in the pre-stored historical cycle or the model parameters of the wall thickness wear value determination model and other related data.

[0040] It should be noted that the wall thickness wear value of the heating surface pipe is also related to the pipe arrangement structure. Due to the sequential arrangement of the pipes, the wear law of the heating surface pipes is characterized by the more serious wear of the first row of pipes on the heating surface, and the wear law of the heating surface pipes is characterized by the more serious wear of the second row of pipes on the heating surface in the staggered arrangement of the pipes. Therefore, different pipe row wear space coefficients can be set for heating surface pipes with different pipe arrangement structures. Among them, the wall thickness wear values ​​of the heating surface pipes corresponding to the sequential structure and the staggered structure are as follows:

[0041] m1=C s1 c km v 3 t;

[0042] m2=C s2 c km v 3 t;

[0043] Wherein, m1 is the wall thickness wear value of the heating surface pipe under the in-line structure, and m2 is the wall thickness wear value of the heating surface pipe under the staggered structure; C s1 is the wear space coefficient of the tube row under the sequential structure, C s2 C is the wear space coefficient of the tube row under the staggered structure. s1 and C s2 The value of can be set manually by relevant technical personnel based on actual experience or experimental values.

[0044] In an optional embodiment, the wall thickness wear value of the heating surface pipe in the current cycle is determined according to the current characteristic parameters and the wall thickness anti-wear coefficient in the historical cycle, including: determining the flue gas flow rate in the environment where the heating surface pipe is located according to the current characteristic parameters; determining the wall thickness wear value of the heating surface pipe in the current cycle according to the flue gas flow rate, the pipe replacement time and the wall thickness anti-wear coefficient in the historical cycle;

[0045] For example, factors influencing the flue gas flow rate in the environment where the heating surface pipe is located can be determined, and a network model for determining the flue gas flow rate can be pre-built.

[0046] Optionally, the flue gas flow rate and fly ash hardness in the environment where the heating surface pipe is located are determined based on the current characteristic parameters, including: determining the flue gas flow rate based on the flue gas volume, pipe diameter and pipe pitch.

[0047] For example, factors affecting the flue gas flow rate may include the electric power of the generator set, the tonnage of coal in the boiler, the flue gas volume, the pitch of the heating surface pipes, the pipe diameter and the pipe area, etc. The relevant data of the factors affecting the flue gas flow rate are obtained, and the obtained relevant data are used as a sample training set to pre-train the pre-built network model for determining the flue gas flow rate, and finally obtain the network model for determining the flue gas flow rate. The input data of the network model for determining the flue gas flow rate in the current cycle, such as the pipe pitch, pipe diameter and flue gas volume, etc., can be obtained based on the trained network model for determining the flue gas flow rate, and the flue gas flow rate in the current cycle can be obtained.

[0048] For example, the wall thickness wear value of the heating surface pipe in the current cycle can be determined based on a preset wall thickness wear value determination model according to the flue gas flow rate, pipe replacement time and wall thickness anti-wear coefficient in historical cycles.

[0049] It should be noted that the wall thickness anti-wear coefficient is related to the material of the heating surface pipe and the hardness of the fly ash, but the wall thickness anti-wear coefficient cannot be directly determined based on the material of the heating surface pipe and the hardness of the fly ash. However, the wall thickness anti-wear coefficient can be continuously corrected during use over time. Specifically, when the wall thickness anti-wear coefficient is used for the first time to determine the wall thickness wear value, the relevant technical personnel can pre-determine the initial value of the wall thickness anti-wear coefficient based on the actual experience value and experimental value, based on the relevant data such as the material of the heating surface pipe and the hardness of the fly ash, and continuously correct the wall thickness anti-wear coefficient in the subsequent process of determining the wall thickness wear value based on the wall thickness anti-wear coefficient, so that the wall thickness anti-wear coefficient becomes more accurate.

[0050] Among them, the fly ash hardness can be determined in the same way as determining the flue gas flow rate, for example, a network model for determining the fly ash hardness can be trained, and based on the trained network model for determining the fly ash hardness, the fly ash hardness in the current cycle can be determined. Exemplarily, the factors affecting the fly ash hardness can include flue gas temperature and fly ash concentration, and the flue gas temperature and fly ash concentration of the environment in which the heating surface pipe is located can be determined based on the amount of coal burned and the power generation power of the generator set. Specifically, the pre-constructed network model for determining the fly ash hardness can be pre-trained based on relevant data such as flue gas temperature and fly ash concentration as a sample training set to obtain the final network model for determining the fly ash hardness. The input data of the network model for determining the fly ash hardness in the current cycle, such as the flue gas temperature and fly ash concentration in the current cycle, can be obtained. Based on the trained network model for determining the fly ash hardness, the fly ash hardness in the current cycle can be obtained.

[0051] Optionally, since the flue gas flow rate changes in real time, the flue gas flow rate can be monitored in real time, and the corresponding flue gas flow rate in the current time period can be the average value of the flue gas flow rate obtained by real-time monitoring in the current time period as the flue gas flow rate in the current period.

[0052] This optional embodiment determines the flue gas flow rate in the environment where the heating surface pipe is located through the current characteristic parameters, and determines the wall thickness wear value of the heating surface pipe in the current cycle according to the flue gas flow rate, pipe replacement time and the wall thickness anti-wear coefficient in the historical cycle, thereby achieving accurate determination of the wall thickness wear value in the current cycle, thereby facilitating the subsequent accurate correction of the wall thickness anti-wear coefficient in the historical cycle according to the wall thickness wear value in the current cycle.

[0053] In an optional embodiment, after determining the wall thickness wear value of the heating surface pipe in the current cycle, it also includes: obtaining the actual wall thickness value of the heating surface pipe determined in the historical cycle; based on the actual wall thickness value in the historical cycle and the wall thickness wear value in the current cycle, determining the wall thickness difference between the actual wall thickness value in the historical cycle and the wall thickness wear value in the current cycle, which is used to indicate the replacement of the heating surface pipe.

[0054] The actual wall thickness value can be the result of subtracting the cumulative value of the wall thickness wear value in each historical period from the initial wall thickness value of the heating surface pipe. That is, in each time period for determining the wall thickness wear value, the actual wall thickness value in the previous historical period is used as the initial wall thickness value in the current period, and the difference between the initial wall thickness value and the wall thickness wear value in the current period is used as the initial wall thickness value in the next time period.

[0055] Exemplarily, the wall thickness difference between the initial value of the wall thickness and the wall thickness wear value in the current cycle can be used as the actual value of the wall thickness in the current cycle. The initial value of the wall thickness is the actual value of the wall thickness in the historical cycle. When the actual value of the wall thickness in the current cycle reaches the preset wall thickness value judgment condition, an early warning can be initiated to the relevant technical personnel to instruct the relevant technical personnel to replace the heating surface pipe. The preset wall thickness value judgment condition can be that the actual value of the wall thickness in the current cycle is less than or equal to the preset wall thickness threshold, and the wall thickness threshold can be pre-set by the relevant technical personnel. For example, the wall thickness threshold can be 60% of the initial value of the wall thickness of the heating surface pipe before it is put into use.

[0056] This optional embodiment determines the wall thickness difference between the initial wall thickness value and the wall thickness wear value in the current cycle according to the initial wall thickness value at the location of the heated surface pipe and the wall thickness wear value in the current cycle, thereby achieving accurate determination of the actual wall thickness value of the heated surface pipe, thereby facilitating subsequent relevant technical personnel to determine whether to replace the pipe according to the actual wall thickness value of the heated surface pipe, thereby avoiding serious impact on the safety of the heated surface pipe.

[0057] S130, according to the wall thickness wear value in the current cycle and the wall thickness wear value in the historical cycle, correct the wall thickness anti-wear coefficient in the historical cycle to obtain the wall thickness anti-wear coefficient in the current cycle.

[0058] It should be noted that since the wall thickness anti-wear coefficient in the historical period is used in determining the wall thickness wear value, there may be changes in the wall thickness anti-wear coefficient in the historical period with the passage of time, changes in the parameters of the heating surface pipe or other external factors, resulting in the wall thickness anti-wear coefficient in the historical period not being accurate enough. After determining the wall thickness wear value in the current period, it is necessary to determine whether the wall thickness wear value in the historical period needs to be corrected.

[0059] In an optional embodiment, the wall thickness anti-wear coefficient in the historical cycle is corrected according to the wall thickness wear value in the current cycle and the wall thickness wear value in the historical cycle, including: determining the wall thickness wear difference according to the wall thickness wear value in the current cycle and the wall thickness wear value in the historical cycle; judging whether the wall thickness anti-wear coefficient in the historical cycle meets the preset anti-wear coefficient correction condition according to the wall thickness wear difference; if so, correcting the wall thickness anti-wear coefficient in the historical cycle.

[0060] The correction condition of the anti-wear coefficient may be preset by relevant technical personnel. For example, the correction condition of the anti-wear coefficient may be that the wall thickness wear difference is greater than or equal to a preset wear difference threshold.

[0061] Exemplarily, the wall thickness wear difference is determined based on the wall thickness wear value in the current cycle and the wall thickness wear value in the historical cycle; it is determined whether the wall thickness wear difference is greater than or equal to a preset wear difference threshold; if so, the wall thickness anti-wear coefficient in the historical cycle is corrected; if not, no correction is made, and the wall thickness anti-wear coefficient in the historical cycle continues to be used when calculating the wall thickness wear value of the heating surface pipe in the next cycle.

[0062] This optional embodiment determines whether to correct the wall thickness anti-wear coefficient in the historical period by judging whether the wall thickness anti-wear coefficient in the historical period meets the preset anti-wear coefficient correction conditions based on the wall thickness wear difference, thereby achieving accurate judgment on whether to correct the wall thickness anti-wear coefficient.

[0063] For example, if after determining the wall thickness wear value in the current cycle, it is judged according to the pre-set anti-wear coefficient correction condition that the wall thickness anti-wear coefficient in the historical cycle needs to be corrected, then the wall thickness anti-wear coefficient can be manually corrected by relevant technical personnel based on actual experience based on the difference between the wall thickness wear value determined in the current cycle and the wall thickness wear value determined in the historical cycle.

[0064] Since the wall thickness wear values ​​determined within the preset time period should be relatively close, whether in the historical period or the current period, the difference between the wall thickness wear values ​​determined in the current period and the wall thickness wear values ​​determined in the historical period should be within a smaller range of variation. If the difference between the wall thickness wear values ​​determined in the current period and the wall thickness wear values ​​determined in the historical period is large, it can be said that the wall thickness wear coefficient is not accurate enough and needs to be adjusted. Since there is a positive proportional relationship between the wall thickness wear value and the wall thickness anti-wear coefficient, relevant technical personnel can compare the wall thickness wear value in the current period with the wall thickness wear value in the historical period, and then correct the wall thickness anti-wear coefficient in the historical period based on the positive proportional relationship between the wall thickness wear value and the wall thickness anti-wear coefficient.

[0065] In an optional embodiment, the wall thickness anti-wear coefficient in the historical cycle is corrected according to the wall thickness wear value in the current cycle and the wall thickness wear value in the historical cycle to obtain the wall thickness anti-wear coefficient in the current cycle, including: determining the average wall thickness wear value according to the wall thickness wear value in the current cycle and the wall thickness wear value in the historical cycle; according to the average wall thickness wear value, based on the correlation between the wall thickness wear value in the current cycle and the current characteristic parameters, correcting the wall thickness anti-wear coefficient in the historical cycle to obtain the wall thickness anti-wear coefficient in the current cycle.

[0066] Among them, the correlation between the wall thickness wear value in the current cycle and the current characteristic parameter can be that the determined value of the wall thickness of the heating surface pipe has a cubic positive correlation with the flue gas flow velocity at the position of the pipe, a first-order positive correlation with the wall thickness anti-wear coefficient, and a first-order positive correlation with the pipe replacement or commissioning time.

[0067] For example, if the wall thickness anti-wear coefficient in the historical cycle needs to be corrected, the average wall thickness wear value between the wall thickness wear value in the current cycle and the wall thickness wear value in the historical cycle can be determined, and the wall thickness wear average value is determined by the ratio of the flue gas flow rate to the cube and the pipe replacement or commissioning time to obtain the corrected wall thickness anti-wear coefficient. The corrected wall thickness anti-wear coefficient can be as follows:

[0068]

[0069] Wherein, v is the flue gas velocity in the current time period, and t is the pipe replacement or commissioning time. It is the average value of the wall thickness wear between the wall thickness wear value in the current cycle and the wall thickness wear value in the historical cycle. The corrected wall thickness anti-wear coefficient is used as the wall thickness anti-wear coefficient in the current cycle, so that when the wall thickness wear value is determined in the next cycle, the wall thickness anti-wear coefficient in the current cycle is used to determine the wall thickness wear value.

[0070] This optional embodiment corrects the wall thickness anti-wear coefficient in the historical period according to the average value of wall thickness wear and the correlation between the wall thickness wear value in the current period and the current characteristic parameter to obtain the wall thickness anti-wear coefficient in the current period, thereby achieving accurate correction of the wall thickness anti-wear coefficient and improving the accuracy of subsequent determination of the wall thickness wear value.

[0071] Optionally, if the wall thickness wear value is determined for the first time in the current cycle, and the corresponding wall thickness anti-wear coefficient is an initial value preset by relevant technical personnel, the wall thickness wear value of the current cycle can be determined based on the preset wall thickness anti-wear coefficient initial value and the wall thickness wear value determination model. If the wall thickness wear value determined to be greater than the preset wall thickness wear value threshold, the average value between the wall thickness wear value of the current cycle and the preset wall thickness wear value threshold can be determined, and the initial value of the wall thickness anti-wear coefficient is corrected based on the average value. The specific correction method is the same as the above correction method, and this embodiment will not be repeated.

[0072] Optionally, the characteristic parameters of the heating surface pipe in the current cycle, as well as the pipe wall thickness wear value, wall thickness anti-wear coefficient and other data at different positions can be displayed to relevant technical personnel in a spatial view data, so that relevant technical personnel can more intuitively obtain the relevant data of the heating surface pipe. In addition, the spatial view data can be updated regularly according to the preset time period, so that relevant technical personnel can better monitor the situation of the heating surface pipe. For example, relevant technical personnel can observe the wear state of the monitored heating surface pipe from different angles and positions, and can select a certain part of the pipe pipeline to directly read the data of that part. When the actual wall thickness value of the heating surface pipe exceeds the preset wall thickness threshold, an alarm is issued, and the pipes in abnormal parts are highlighted with special colors.

[0073] Optionally, when the heating surface pipes are replaced, the previous wall thickness anti-wear coefficient can continue to be used, and it is only necessary to reset the pipe renewal time of the pipe after the replacement.

[0074] The embodiment of the present invention realizes accurate determination of the wall thickness wear value of the heating surface pipe in the current cycle according to the current characteristic parameters in the current cycle and the anti-wear coefficient in the historical cycle; by correcting the wall thickness anti-wear coefficient in the historical cycle according to the wall thickness wear value in the current cycle and the wall thickness wear value in the historical cycle, the wall thickness anti-wear coefficient in the current cycle is obtained, and continuous correction of the wall thickness anti-wear coefficient is realized in the process of determining the wall thickness wear value, thereby improving the accuracy of the wall thickness anti-wear coefficient, and further improving the accuracy of determining the wall thickness wear value, avoiding leakage or pipe burst accidents caused by inaccurate determination of the wall thickness wear value, which affects the safe operation of the boiler.
