TECHNICAL FIELD
[0001] The present application relates to the technical field of power plant boilers, in particular to a high-alkali coal deep peak regulation self-adaptive combustion optimization system and method. BACKGROUND
[0002] In the field of high-alkali coal deep peak regulation combustion optimization, the existing technology lacks precision in the collection of combustion parameters and the evaluation of combustion state. When the traditional system collects high-alkali coal combustion parameters, it does not perform strict signal conditioning and time sequence marking, resulting in problems such as poor consistency and time sequence misplacement of parameter data, which cannot provide reliable data support for combustion state evaluation. When evaluating combustion stability and slagging tendency, only temperature or flue gas composition data is analyzed, without dynamic weight allocation based on operating conditions for comprehensive quantitative evaluation, making the evaluation results one-sided and difficult to accurately reflect the actual combustion state of high-alkali coal, which poses hidden dangers for subsequent parameter adjustment.
[0003] The existing technology has obvious defects in parameter adjustment and strategy optimization. When generating parameter adjustment instructions, the control priority is not reasonably sorted, and the applicability and logical consistency of the adjustment rules are not verified, which may lead to mismatch between the instructions and the operating state of the combustion equipment, and even cause equipment operation risks. In the optimization process, there is a lack of comprehensive monitoring of the dynamic changes of combustion after parameter adjustment, and an adaptive strategy updating mechanism based on verification data is not constructed. Only fixed strategies are used for static adjustment, which cannot adapt to the dynamic changes of the high-alkali coal combustion process in real time, and it is difficult to achieve efficient combustion optimization in the deep peak regulation scenario.

[0028] The following will be described in combination with specific embodiments, respectively for each component and specific work flow of the high-alkali coal deep peak shaving adaptive combustion optimization system: The data acquisition module 101 is configured to integrate and acquire a plurality of parameter data of the high-alkali coal in the combustion process to obtain a monitoring data set of the high-alkali coal. In the embodiment of the present application, the data acquisition module acquires a plurality of parameter data of the high-alkali coal in the combustion process after performing integrated acquisition, to obtain a monitoring data set of the high-alkali coal, which is specifically used for: synchronously acquiring a plurality of parameter data of the high-alkali coal in the combustion process, to obtain initial parameter data of the high-alkali coal; performing signal conditioning on the initial parameter data, to obtain regularized parameter data of the high-alkali coal; verifying consistency of the regularized parameter data, to obtain verified parameter data of the high-alkali coal; based on a preset time reference, performing time sequence alignment on the verified parameter data, to obtain time sequence aligned parameter data of the high-alkali coal; integrating the time sequence aligned parameter data into the monitoring data set of the high-alkali coal.
[0029] Specifically, when the plurality of parameter data of the high-alkali coal in the combustion process are synchronously acquired to obtain the initial parameter data of the high-alkali coal, temperature, pressure, flue gas composition and other sensors are deployed at key positions of the combustion equipment, and original data are simultaneously acquired and stored in a unified frequency.

[0036] In summary, the consistency of the regularized parameter data is verified to ensure that data from different sources or different types match and confirm each other, avoid data conflicts and contradictions, ensure the accuracy and reliability of the data, and make decisions and judgments based on the data more reliable.
[0037] In summary, the time sequence of the verified parameter data is aligned based on the preset time reference, which can make the data collected at different times have a clear time sequence and corresponding relationship, which is very important for analyzing the trend of parameters changing over time and the dynamic correlation between parameters in the high-alkali coal combustion process, and helps to find potential rules and problems in the combustion process.

[0055] Further, when the weighted stability index is nonlinearly transformed based on the first dynamic adjustment factor, a preset nonlinear processing mode is adopted, the transformation strength is dynamically controlled according to the size of the adjustment factor, the deviation part of the original index is corrected, and finally the transformed stability index accurately reflecting the actual situation of the combustion stability is obtained.
[0056] Further, when the weighted slagging tendency index is exponentially smoothed based on the second dynamic adjustment factor, a fixed smoothing initial value is taken as the basis, an adjustment amount is obtained by combining the product of the index and the adjustment factor, a smoothing value is generated by multiple rounds of iteration fusion, short-term fluctuation interference is eliminated, and the transformed slagging tendency index reflecting the long-term trend of the slagging tendency is obtained.
[0057] Further, when determining the coupling effect coefficient, the change trend correlation of the two transformed indexes is analyzed, the change amplitude ratio in the same time period is calculated, and the corresponding coefficient is matched according to the preset coupling effect coefficient corresponding table according to the ratio. The coefficient size is positively correlated with the index correlation degree.
[0058] Further, when calculating the comprehensive combustion state evaluation value, first, fixed basic weights are allocated to the two transformed indexes and the weighted sum is calculated, and then the weighted sum is multiplied by the coupling effect coefficient, so as to fully integrate the information of the combustion stability, the slagging tendency and the coupling relationship between the two, and obtain the comprehensive combustion state evaluation value.
[0059] Specifically, the transformed stability index is obtained by nonlinear transformation of the weighted stability index based on the first dynamic adjustment factor, and the weighted stability index is obtained by quantitatively correcting the combustion stability determination result by the first weight factor, and the combustion stability determination result is obtained by mapping the temperature change characteristic data to the preset stability standard.

[0062] Further, the nonlinear adjustment parameter is a preset fixed parameter calibrated based on a large amount of high-alkali coal combustion experimental data, and is used to regulate the amplitude of nonlinear transformation.
[0063] Further, the coupling effect coefficient is obtained by analyzing the change trend correlation of the transformed stability index and the transformed slagging tendency index, calculating the change amplitude ratio of the two in the same time period, and then matching the preset coupling effect coefficient corresponding table.
[0064] Further, the formula has the meaning of comprehensively integrating the information related to the combustion stability and slagging tendency in the high-alkali coal combustion process, and accurately calculating the comprehensive combustion state evaluation value. By introducing the first dynamic adjustment factor and the second dynamic adjustment factor, the transformed stability index and the transformed slagging tendency index are respectively corrected, and the accuracy of the single index is improved. The non-linear transformation degree of the index is adjusted by means of the non-linear adjustment parameter, so that the index is more in line with the actual combustion state characteristics. The coupling effect coefficient is used to quantify the coupling effect between the two indexes according to the numerical difference between the two indexes, and finally the evaluation value which can comprehensively reflect the overall state of high-alkali coal combustion is obtained by integration calculation, which provides a scientific basis for the judgment of the combustion state.
[0065] Further, from the trend of the formula, the higher the transformed stability index and the lower the transformed slagging tendency index, the higher the comprehensive combustion state evaluation value. The increase of the first dynamic adjustment factor and the decrease of the second dynamic adjustment factor will respectively improve the positive contribution of the two indexes to the evaluation value. When the non-linear adjustment parameter increases, the sensitivity of the index to the evaluation value decreases. When the coupling effect coefficient increases, the larger the numerical difference between the two indexes, the more obvious the adjustment of the evaluation value, and the smaller the numerical difference, the weaker the adjustment effect.

[0067] Overall, the temperature change characteristic data is obtained by analyzing the change trend of the combustion temperature time series data, which can clearly capture the key information such as the fluctuation rule and the change rate of the temperature in the combustion process. These information directly reflects the stability degree of the combustion state, and provides detailed characteristics for the judgment of the combustion stability, making the stability evaluation more scientific.
[0068] Overall, the alkali component concentration data is obtained by identifying the alkali component of the flue gas composition time series data, and the core substance concentration information affecting the slagging tendency of high-alkali coal is accurately obtained. Because the content of alkali component is the key factor leading to slagging of the combustion equipment, this step provides accurate quantitative data basis for the evaluation of slagging tendency.
[0069] Overall, the combustion stability judgment result is obtained by mapping the temperature change characteristic data to the preset stability standard. Through the standardized comparison, the evaluation of the combustion stability has a clear reference basis, avoiding the error caused by subjective judgment, and ensuring the objectivity and consistency of the judgment result.
[0070] In summary, the concentration data of the basic component is compared with the preset slagging benchmark in multiple stages to obtain the slagging tendency determination result, and the multiple-stage comparison can finely distinguish the difference in slagging tendency in different concentration intervals, making the evaluation of the slagging tendency more accurate and comprehensive, and providing a precise direction for subsequent targeted adjustment.

[0072] In summary, the operating condition data of high-alkali coal is obtained and the condition parameter representing the load state of the boiler is obtained, which can accurately capture the key external operating conditions affecting the combustion state of high-alkali coal, because different boiler loads will directly change the combustion intensity, temperature distribution and flue gas composition. By including this parameter in the evaluation process, the evaluation deviation caused by deviating from the actual running scene can be avoided, and the subsequent evaluation can be more in line with the real running state of the equipment.
[0073] In summary, the first weight factor of the combustion stability determination result and the second weight factor of the slagging tendency determination result are determined according to the condition parameter, realizing the dynamic adaptation of the evaluation weight, for example, the combustion stability has a more significant impact on the safe operation of the equipment in high-load conditions, and the first weight factor can be increased, and the slagging tendency prevention and control is more critical in low-load conditions, and the second weight factor can be increased, avoiding the limitations of traditional fixed weight evaluation that cannot adapt to different conditions, and making the weight distribution more reasonable and targeted.
[0074] In summary, the weighted stability index is obtained by quantitatively correcting the combustion stability determination result based on the first weight factor, and the influence of the condition is integrated into the quantification process of the stability determination result, so that the stability index not only reflects the temperature change characteristics, but also reflects the actual importance of stability under the current condition, improving the scene adaptability and quantitative accuracy of the stability index, and providing more reliable single-dimensional data support for subsequent comprehensive evaluation.
[0075] In summary, the weighted slagging tendency index is obtained by normalizing the slagging tendency determination result based on the second weight factor, on the one hand, the data dimension difference under different slagging determination standards is eliminated through normalization, and on the other hand, the condition-related attribute is given a weight, so that the slagging tendency index can not only accurately reflect the influence of the concentration of the basic component, but also match the priority of slagging prevention and control under the current condition, ensuring that the index and the weighted stability index have a comparable and integrable basis.
[0076] Overall, the comprehensive combustion state evaluation value is obtained by linear evaluation of the weighted stability index and the weighted slagging tendency index, realizing the organic integration of the two key evaluation dimensions, avoiding the one-sidedness of single-dimensional evaluation, reasonably reflecting the influence of the two indexes in the comprehensive result through linear evaluation, forming the overall quantitative cognition of the high-alkali coal combustion state, and providing intuitive and comprehensive numerical basis for subsequent judgment.
[0077] Overall, the combustion stability and slagging tendency are determined by comparing the comprehensive combustion state evaluation value with the preset multi-level threshold value, and the evaluation level is refined by the multi-level threshold value, which can accurately distinguish the differences in combustion state corresponding to different comprehensive evaluation values, such as the levels of good, medium and poor of combustion stability and the levels of high, medium and low of slagging tendency when the comprehensive value is in different intervals, avoiding the problem of too rough judgment by traditional single threshold value, making the final combustion stability and slagging tendency more accurate and specific, and providing clear and reliable decision support for the generation of targeted parameter adjustment instructions by the instruction analysis module.
[0078] Overall, the first dynamic adjustment factor and the second dynamic adjustment factor are generated according to the weighted stability index and the weighted slagging tendency index, which can deeply bind the adjustment factor with the actual numerical characteristics of the two core indexes, avoid the problem of insufficient adaptability caused by using fixed adjustment coefficient, and ensure that the subsequent processing of the two indexes can accurately match the actual influence degree of the indexes under the current combustion state, providing an adaptive basis for index optimization processing.
[0079] Overall, the transformed stability index is obtained by nonlinear transformation of the weighted stability index based on the first dynamic adjustment factor, which can amplify or correct the numerical characteristics that are critical to the evaluation of the combustion state in the weighted stability index, such as increasing the influence weight of the index value close to the critical value on the comprehensive evaluation, solving the problem that linear processing cannot highlight the key numerical differences, and making the stability index more accurately reflect the actual combustion stability state.
[0080] Overall, the transformed slagging tendency index is obtained by exponential smoothing processing of the weighted slagging tendency index based on the second dynamic adjustment factor, which can effectively eliminate the abnormal data interference in the slagging tendency index caused by measurement fluctuations, and adapt the smoothing degree to the change rate of the slagging tendency under the current working condition through the dynamic adjustment factor, avoiding the problems of lagging or excessive smoothing caused by fixed smoothing parameters, making the slagging tendency index more stable and reliable.
[0081] In general, the coupling effect coefficient is determined according to the correlation between the transformed stability index and the transformed slagging tendency index, the mutual influence relationship between the two indexes can be accurately captured, for example, the correlation rule that the improvement of combustion stability may be accompanied by the change of slagging tendency, the correlation rule is quantified as the coupling effect coefficient and is included in the comprehensive evaluation, the deviation of the result caused by ignoring the interaction between indexes in the traditional evaluation is avoided, and the comprehensive evaluation is more in line with the actual situation of the interaction between various factors of the combustion system.
[0082] In general, by combining the transformed stability, the slagging tendency index and the coupling effect coefficient, the comprehensive combustion state evaluation value is calculated through a specific formula, the dynamic weight distribution, the index correlation influence and the numerical difference refinement processing are integrated, multi-dimensional fine quantitative evaluation is realized, the one-sidedness problem of the traditional evaluation is solved, and the obtained evaluation value can accurately reflect the actual combustion state, thereby providing a scientific basis for subsequent determination.

[0098] In summary, the adaptation rules of the adaptive adjustment strategy selected based on the comprehensive control sequence form an adjustment rule set, which allows the rule selection to closely match the current control priority and avoid selecting rules unrelated to the core demand, ensuring that each rule in the rule set can directly serve the optimization of combustion stability or slagging tendency, and improving the relevance and practicality of the rules.
[0099] In summary, the verification of the adjustment rule set for applicability obtains verified adjustment rules, which can exclude rules that do not match the current high-alkali coal combustion conditions, such as high-load control rules that are not applicable in low-load conditions, avoiding parameter adjustment deviations caused by rule mismatch and ensuring the rationality of subsequent control parameter modification.
[0100] In summary, the verified adjustment rules are converted into control parameter modification, abstract rule requirements are converted into specific and executable parameter variation standards, and quantitative basis is provided for the generation of parameter adjustment instructions, avoiding the lack of specific numerical support for the implementation of the instructions.
[0101] In summary, the parameter adjustment instructions are generated based on the control parameter modification, integrating all previous control logic and quantitative data to form operation instructions that can be directly issued to the combustion equipment, effectively solving the problem of disconnection between traditional instruction generation and control demand and working condition adaptation, ensuring that the instructions can accurately point to the optimization target of combustion stability and slagging tendency, and providing clear basis for the operation of the subsequent state execution module.
[0102] In summary, the real-time state data of high-alkali coal is divided into regional situations based on the preset safe operation parameter range to obtain a safe adjustment boundary, which can clearly define the safe interval of parameter adjustment, avoid subsequent parameter modification exceeding the safe operation range of the equipment, and prevent equipment failure or combustion safety risks caused by parameter abnormalities from the source, providing a safety benchmark for parameter adjustment.

According to the control parameter identifier, the execution mechanism in the combustion equipment is matched to obtain a parameter mapping relationship of the combustion equipment. The target setting value is mapped to the parameter mapping relationship to obtain a driving signal of the combustion equipment. The driving signal is transmitted to the execution mechanism to trigger a parameter adjustment action of the combustion equipment. The actual response state of the parameter adjustment action is monitored to obtain a parameter actual adjustment value of the parameter adjustment action.

[0117] In general, the target set value is mapped to the parameter mapping relationship to generate a driving signal, which converts the abstract parameter target into a specific signal recognizable by the actuator, so that the actuator can clearly know the adjustment direction and target, solves the problem of incompatibility between the instruction and the device signal, and ensures that the actuator can accurately start the adjustment action according to the driving signal.
[0118] In general, the driving signal is transmitted to the actuator to trigger the parameter adjustment action, which realizes the effective connection from the instruction to the device operation, avoids the adjustment lag caused by the interruption or delay of signal transmission, ensures that the parameter adjustment action starts in time according to the instruction requirement, guarantees that the combustion equipment can quickly respond to the optimization demand, and improves the timeliness of parameter adjustment.
