Description

Technical Field

[0001] The present invention belongs to the technical field of data analysis, and in particular relates to a burner and a combustion data analysis method. Background Art

[0002] Incineration is a common method of treating garbage. However, if there is a deviation in the combustion data control, it will inevitably lead to slagging problems, which will have a certain impact on the service life and reliability of the burner.

[0003] In the existing technical solutions, CFD numerical simulation is often used to monitor temperature data and combustion parameters to achieve real-time prediction of slagging tendency, so as to achieve real-time adjustment of combustion parameters. Specifically, similar technical solutions are given in the invention patent application CN202311164117.9 "A system and method for real-time monitoring and anti-slagging optimization of water-cooled walls of coal-fired boilers" and CN202310926507.9 "A method for analyzing data of blended combustion in a coal yard". However, the above technical solutions all have the following technical problems:

[0004] Unlike coal-fired boilers, the composition of garbage combustion is more complex. Therefore, due to the large differences in historical combustion data, it is difficult to ensure the accuracy of the CFD numerical simulation model when using the above method, and thus it is impossible to use the above method to achieve accurate control of the slagging tendency.

[0005] In view of the above technical problems, the present invention provides a burner and a combustion data analysis method. Summary of the invention

[0006] To achieve the purpose of the present invention, the present invention adopts the following technical solutions:

[0007] According to one aspect of the present invention, a combustion data analysis method is provided.

[0008] A combustion data analysis method, specifically comprising:

[0009] S1 determines the similarity of the blending data of the target type of garbage between different historical incineration times, and determines the available blending material type based on the distribution of the combustion data at different historical combustion times, and determines the corresponding historical combustion times of the available blending material type based on the blending data, and uses it as the corresponding combustion times;

[0010] S2: determining combustion data at corresponding combustion times under different available blending material types, and using the combustion data to classify the corresponding combustion times into different combustion data similarity groups, and when it is determined based on the slagging data at corresponding combustion times of the combustion data similarity groups that the available blending material type can meet the slagging control requirement, proceeding to the next step;

[0011] S3: using the slagging data under different corresponding combustion times to determine the group with excellent slagging control among the groups with similar combustion data, and determining the slagging control difficulty under the available blending material type based on the combustion data distribution and the slagging data, and determining the slagging control type with simple slagging control among the available blending material types by using the slagging control difficulty;

[0012] S4 obtains historical recycling data of garbage corresponding to the slagging control type, and determines the blending target of the target type of garbage based on the historical recycling data and the slagging control difficulty.

[0013] A further technical solution is that the blending data includes blending ratios of different types of garbage.

[0014] A further technical solution is that the combustion data includes ventilation volume and combustion temperature.

[0015] A further technical solution is to divide the corresponding combustion times into different combustion data similarity groups, specifically including:

[0016] Based on the average values ​​of the deviation of the blending ratio and the deviation of the combustion temperature under different corresponding combustion times, the data similarity coefficient between different corresponding combustion times is evaluated;

[0017] The corresponding combustion times whose data similarity coefficient is greater than the preset similarity coefficient are divided into the same combustion data similarity group.

[0018] A further technical solution is to determine whether the available blending material type can meet the slagging control requirements, specifically including:

[0019] Determine the slagging ratio under the corresponding combustion times of the combustion data similar group, and determine the average value of the deviation of the slagging ratio by using the deviation of the slagging ratio between different corresponding combustion times, and divide the slagging ratio consistent group in the combustion data similar group according to the average value of the deviation of the slagging ratio;

[0020] The number of combustions corresponding to the slagging ratio not being within the preset slagging ratio interval is taken as the number of abnormal slagging combustions, and a valid group in the group with consistent slagging ratio is determined based on whether there is an abnormal slagging combustion number in the group with consistent slagging ratio;

[0021] The corresponding combustion times in the effective group are used to determine whether the available blending material type can meet the slagging control requirement.

[0022] A further technical solution is that when the corresponding combustion number in the effective group is greater than the preset combustion number, it is determined that the available blending material type can meet the slagging control requirement.

[0023] A further technical solution is that the method for determining the target of the co-combustion of the target type of waste is as follows:

[0024] Determining a historical recycling volume based on historical recycling data, and determining a preset control difficulty threshold corresponding to the historical recycling volume according to the historical recycling volume;

[0025] The control difficulty threshold and the slagging control difficulty are used to determine whether the slagging control type is a target for the blending and combustion of target type of waste.

[0026] A further technical solution is that the preset control difficulty threshold is determined according to the size of the historical recycling processing volume, wherein the larger the historical recycling processing volume is, the smaller the preset control difficulty threshold is.

[0027] A further technical solution is that when the slagging control difficulty of the slagging control type is less than the control difficulty threshold, the slagging control type is determined as the co-combustion target of the target type of waste.

[0028] In another aspect, the present invention provides a burner, using the above-mentioned combustion data analysis method, specifically comprising:

[0032] The control difficulty evaluation module is responsible for determining the slagging control excellent group of the combustion data similar group by using the slagging data under different corresponding combustion times, and determining the slagging control difficulty under the available blending material type based on the combustion data distribution and the slagging data, and determining the slagging control type with simple slagging control among the available blending material types by using the slagging control difficulty;

[0033] The co-combustion target determination module is responsible for obtaining the historical recycling data of the garbage corresponding to the slagging control type, and determining the co-combustion target of the target type of garbage based on the historical recycling data and the slagging control difficulty.

[0034] The beneficial effects of the present invention are:

[0035] 1. In the present invention, the types of available blending materials are determined by taking into account the similarity of the blending data between different historical incineration times and the distribution of the combustion data at different historical incineration times, thereby taking into account the similarity of the combustion temperatures between different historical incineration times and the similarity of the types and proportions of the blended garbage between different historical incineration times, thereby achieving the determination of the types of available blending materials for which the combustion data and blending data at different historical incineration times are relatively similar, thereby also laying a foundation for optimizing the slagging control based on the combustion data and blending data.

[0036] 2.

[0051] Slag control type with simple slag control: The slag control difficulty of less than 0.5 is regarded as the slag control type with simple slag control.

[0052] The incineration target of the target type of garbage: the historical recycling volume is determined based on the historical recycling data, and the preset control difficulty threshold corresponding to the historical recycling volume is determined based on the historical recycling data. The control difficulty threshold and slagging control difficulty are used to determine whether the slagging control type is the incineration target of the target type of garbage.

[0094] The slagging control consistency of different groups with consistent slagging ratios is determined according to the proportion of the number of similar combustion times in the group with consistent slagging ratios. The slagging control consistency of different groups with similar combustion data and the weights of slagging control anomalies are used to determine the slagging control effectiveness of different groups with similar combustion data.

[0099] The slagging control consistency of different combustion data similar groups, the weight of the slagging control abnormal value and the slagging control effectiveness of different combustion data similar groups are used to determine the slagging control excellent group.

[0100] Specifically, Figure 4 As shown, the method for determining the difficulty of slagging control under the available blending material type is:

If so, proceed to the next step; if not, determine that the available blending material type does not belong to the slagging control type.

[0108] Determine the slagging amount of different excellent slagging control groups by using the slagging data, and judge whether there is a slagging control beneficial group with a slagging amount within a preset range, if yes, proceed to the next step, if not, determine that the available blending material type does not belong to the slagging control type;

[0109] Determine the slagging amount of different excellent slagging control groups by using the slagging data, determine the slagging interval control difficulty of different temperature sub-intervals by the distribution range of different temperature sub-intervals and the slagging amount of the excellent slagging control group corresponding to the temperature sub-intervals, and judge whether there is a temperature sub-interval whose slagging interval control difficulty meets the requirements, if so, proceed to the next step, if not, determine that the available blending material type does not belong to the slagging control type;

[0111] S4 obtains historical recycling data of garbage corresponding to the slagging control type, and determines the blending target of the target type of garbage based on the historical recycling data and the slagging control difficulty.

[0112] Specifically, the method for determining the target of the target type of waste to be incinerated is as follows:

[0113] Determining a historical recycling volume based on historical recycling data, and determining a preset control difficulty threshold corresponding to the historical recycling volume according to the historical recycling volume;

[0114] The control difficulty threshold and the slagging control difficulty are used to determine whether the slagging control type is a target for the blending and combustion of target type of waste.

[0115] Furthermore, the preset control difficulty threshold is determined according to the size of the historical recycling processing volume, wherein the larger the historical recycling processing volume is, the smaller the preset control difficulty threshold is.

[0116] It can be understood that when the slagging control difficulty of the slagging control type is less than the control difficulty threshold, the slagging control type is determined to be the co-combustion target of the target type of waste.
