Description

Technical Field

[0001] This invention relates to the field of boiler combustion optimization technology, and in particular to a method and apparatus for suppressing boiler combustion delay. Background Technology

[0002] A boiler's variable load capacity is related to its operational flexibility and fault tolerance; therefore, it is often necessary to pay attention to this capacity. Boiler combustion delay is a crucial factor affecting its variable load characteristics; generally, the shorter the combustion delay, the stronger the boiler's variable load capacity. Therefore, it is essential to suppress boiler combustion delay.

[0003] Currently, several boiler combustion delay suppression schemes exist, and relevant personnel can adjust or design corresponding schemes based on actual conditions. However, some boiler combustion delay suppression schemes may have anomalies, such as significant room for improvement or certain defects. In such cases, using the scheme for combustion delay suppression may not yield ideal results and may fail to meet expectations. In existing technologies, detecting anomalies in the configuration information of boiler combustion delay suppression schemes typically relies on the principles and experience of assessing internal combustion engine combustion delay. However, the operating conditions and characteristics of internal combustion engines differ from those of boilers, leading to low accuracy in detecting anomalies in the configuration information. This may result in the application of combustion delay suppression schemes with anomalies, hindering the improvement of boiler combustion delay suppression effectiveness.

[0004] In summary, the existing technology has the problem of low accuracy in detecting whether the boiler combustion delay suppression configuration information is abnormal, which is not conducive to improving the boiler combustion delay suppression effect. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] The terms “include,” “including,” “have,” “contain,” etc., used in this article are all open-ended terms, meaning that they include but are not limited to.

[0066] The term "and / or" as used herein includes any or all of the things mentioned.

[0067] It should be noted that the acquisition, storage, use, and processing of data in the technical solution of this invention all comply with the relevant provisions of national laws and regulations.

[0068] It should be noted that the boiler combustion delay suppression method and apparatus disclosed in this application can be used in the field of boiler combustion optimization technology, or in any field other than boiler combustion optimization technology. The application field of the boiler combustion delay suppression method and apparatus disclosed in this application is not limited.

[0069] This invention discloses a method for suppressing boiler combustion delay, such as... Figure 1 As shown, the method specifically includes the following steps:

[0070] S101: Obtain the combustion rate based on the reaction temperature parameter, reaction kinetic parameter, and fuel size parameter corresponding to the combustion delay suppression configuration information.

[0071] S102: Obtain the predicted combustion delay time based on the fuel property parameter corresponding to the combustion delay suppression configuration information, the preset fuel combustion consumption volume, the preset equipment performance coefficient, and the combustion rate.

[0072] S103: Based on the measured combustion delay time and the predicted combustion delay time, determine whether the combustion delay suppression configuration information is abnormal. If not, perform boiler combustion configuration and boiler combustion based on the combustion delay suppression configuration information.

[0073] Exemplarily, the combustion delay can be defined as, but not limited to, the time required for most of the heat in the fuel to be released from the moment the fuel enters the furnace, or the time for the combustibles with a proportion of X (0 < X < 1) in the fuel entering the furnace to complete the combustion reaction, etc. Among them, the combustion delay is generally related to the properties and initial temperature of the input fuel, etc. It should be noted that the specific definition and properties of the combustion delay, etc., can be determined by those skilled in the art according to the actual situation. The above description is only an example and does not constitute a limitation thereto.

[0074] Exemplarily, the delay suppression configuration information involved in the embodiments of the present invention can be, but not limited to, the configuration information corresponding to the corresponding combustion delay suppression scheme, and the combustion delay suppression scheme can specifically be, but not limited to, one or more of the specific improvement schemes for fuel particle size, fuel material, boiler equipment structure, boiler equipment components, boiler equipment operation settings, boiler equipment initialization settings, boiler load (for example, the boiler load can take, but not limited to, 100% load, 75% load, and 50% load, etc.) or boiler control mode, etc. Correspondingly, the delay suppression configuration information in the embodiments of the present invention can be, but not limited to, the corresponding fuel configuration information and / or boiler equipment configuration information, etc., specifically including but not limited to fuel particle size, fuel material, fuel purity, boiler load ratio, boiler opening, combustion temperature, boiler structure information, boiler component setting information, and boiler operation parameter information, etc. It should be noted that the nature and content of the delay suppression configuration information and the delay suppression scheme, etc., can be determined by those skilled in the art according to the actual situation. The above description is only an example and does not constitute a limitation thereto.

[0075] Exemplarily, the measured combustion delay time in the embodiments of the present invention can be directly measured and obtained through, but not limited to, laboratory tests and / or actual furnace tests based on the boiler. For example, as Figure 2 shown, in a certain actual furnace combustion test, the fuel quantity had a step at time t0, and correspondingly, as Figure 3As shown, the boiler temperature (e.g., furnace temperature, but not limited to) does not immediately rise at time t0, but only begins to rise at time t1. Since time t1 is later than time t0, the time difference between time t1 and time t0 is the corresponding measured combustion delay time. It should be noted that the source of the measured combustion delay time can be determined by those skilled in the art based on the actual situation. The above description is merely an example and does not constitute a limitation.

[0076] For example, configuring and executing boiler combustion based on the combustion delay suppression configuration information can be, but is not limited to, setting boiler parameters corresponding to the combustion delay suppression configuration information and controlling the boiler to burn; or, sending the combustion delay suppression configuration information to the corresponding operator so that the operator can improve the boiler's structure, materials, equipment type and operating mode, and / or fuel selection and pretreatment based on the combustion delay suppression configuration information, and then debug or put the boiler into operation to achieve boiler combustion. It should be noted that the specific implementation method for configuring and executing boiler combustion based on the combustion delay suppression configuration information can be determined by those skilled in the art according to the actual situation. The above description is merely an example and does not constitute a limitation.

[0077] The boiler combustion delay suppression method and apparatus provided by this invention obtain the combustion rate based on reaction temperature parameters, reaction kinetic parameters, and fuel size parameters corresponding to the combustion delay suppression configuration information. It accurately obtains a combustion rate consistent with actual conditions based on actual thermodynamic characteristics collected under test operating conditions corresponding to the combustion delay suppression configuration information, thereby improving the accuracy of determining the predicted combustion delay time and consequently improving the overall accuracy of detecting whether the boiler combustion delay suppression configuration information is abnormal. Furthermore, by obtaining the predicted combustion delay time based on fuel characteristic parameters, preset fuel combustion consumption volume, preset equipment performance coefficient, and the combustion rate corresponding to the combustion delay suppression configuration information, it fully considers the impact of equipment performance and fuel conditions on boiler operation, based on relevant physicochemical laws. Accurate calculations yield the predicted combustion delay time, thereby improving the accuracy of detecting whether boiler combustion delay suppression configuration information is abnormal based on the predicted combustion delay time. By determining whether the combustion delay suppression configuration information is abnormal based on the measured combustion delay time and the predicted combustion delay time, if not, boiler combustion configuration and combustion are performed based on the combustion delay suppression configuration information. This allows for an accurate determination of whether the actual suppression effect of the suppression scheme corresponding to the combustion delay suppression configuration information matches the corresponding expectations, thus improving the accuracy of detecting whether boiler combustion delay suppression configuration information is abnormal. Only when the boiler combustion delay suppression configuration information is not abnormal and matches the corresponding expectations is the corresponding suppression scheme applied, thereby improving the effect of boiler combustion delay suppression.

[0078] In summary, the present invention can improve the accuracy of detecting whether the boiler combustion delay suppression configuration information is abnormal, thereby improving the boiler combustion delay suppression effect.

[0079] In one alternative implementation, such as Figure 4 As shown, the combustion rate is obtained based on the reaction temperature parameters, reaction kinetic parameters, and fuel size parameters corresponding to the combustion delay suppression configuration information, including the following steps:

[0080] S401: Based on the reaction temperature parameters, determine the corresponding gas phase temperature and particle phase temperature.

[0081] S402: Based on the aforementioned reaction kinetic parameters, determine the corresponding pre-exponential factor and reaction activation energy.

[0082] S403: Determine the corresponding fuel radius based on the fuel size parameters.

[0083] S404: The combustion rate is obtained based on the gas phase temperature, particulate phase temperature, pre-exponential factor, reaction activation energy, and fuel radius.

[0084] For example, step S401 may involve, but is not limited to, analyzing the reaction temperature parameters to obtain the reaction temperature parameters, including or corresponding reaction gas phase temperature and particulate phase temperature. The reaction gas phase temperature can be obtained by measuring the boiler gas temperature (e.g., but not limited to, furnace gas temperature) using an instrument such as a high-temperature infrared thermometer under the boiler operating conditions corresponding to the current combustion delay suppression configuration information (characterizing the combustion delay suppression scheme), but not limited to. The particulate phase temperature can be obtained by measuring the fuel particle temperature in the boiler using an instrument such as a high-temperature infrared thermometer under the boiler operating conditions corresponding to the current combustion delay suppression configuration information (characterizing the combustion delay suppression scheme), but not limited to. Correspondingly, the boiler operating conditions may correspond to, but are not limited to, boiler operating conditions under actual furnace tests, laboratory tests, or actual boiler production operation environments. The particulate phase temperature may also be equivalent to, but not limited to, the solid phase temperature corresponding to the fuel. It should be noted that the specific implementation of step S401 and the specific sources of the reaction gas phase temperature and particulate phase temperature can be determined by those skilled in the art based on actual circumstances. The above description is merely an example and does not constitute a limitation.

[0085] For example, step S402 may involve, but is not limited to, analyzing the reaction kinetic parameters to obtain the pre-exponential factor and activation energy, which are included or corresponding to the reaction kinetic parameters. The pre-exponential factor and activation energy are parameters related to physicochemical properties and fuel characteristics, and can be obtained through methods such as experimental testing under the boiler operating conditions corresponding to the current combustion delay suppression configuration information (characterizing the combustion delay suppression scheme), but not limited to such methods. It should be noted that the specific implementation of step S402 and the specific sources of the pre-exponential factor and activation energy can be determined by those skilled in the art based on actual circumstances; the above description is merely an example and does not constitute a limitation.

[0086] For example, step S403 may include, but is not limited to, analyzing the fuel size parameters to obtain the fuel radius included in the fuel size parameters. The fuel radius may be, but is not limited to, the radius of the corresponding fuel particle or the particle size of the fuel powder (which may be, but is not limited to, the conventional radius or average radius, taking the condition of intact particles, i.e., the corresponding size of the particles when they are not burned), etc. Specifically, its properties may be, but are not limited to, the radius corresponding to when the fuel particles are imagined as spheres, and can be directly obtained by, but is not limited to, consulting relevant materials, instructions, configuration information, or performing relevant measurements. It should be noted that the specific implementation of step S403 and the source and properties of the fuel radius can be determined by those skilled in the art based on the actual situation. The above description is only an example and does not constitute a limitation.

[0087] For example, step S404 can be expressed as, but is not limited to, the following formula:

[0088]

[0089] Among them, K T The current combustion rate is represented by the unit (which may be, but is not limited to, kmol / s), A represents the current pre-exponential factor, and T represents the current pre-exponential factor. g The current gas phase temperature of the reaction is represented by T, e represents the natural constant, E represents the current activation energy of the reaction, R represents the current fuel radius, and T represents the current gas phase temperature of the reaction. p This indicates the current particle phase temperature.

[0090] The combustion rate can characterize, but is not limited to, the amount of fuel consumed per unit time, and is related to factors including but not limited to the composition of the combustion-supporting agent, diffusion conditions, fuel composition, and combustion temperature.

[0091] By following the steps described above, based on the relevant principles and laws of chemical reaction kinetics and by fully analyzing the relevant parameters, and using more detailed physicochemical indicators as input, the corresponding current combustion rate can be determined more accurately. This improves the accuracy of detecting whether the overall boiler combustion delay suppression configuration information is abnormal, and thus enhances the effect of boiler combustion delay suppression.

[0092] In an optional implementation, it further includes:

[0093] Before obtaining the predicted combustion delay time based on the fuel characteristic parameters corresponding to the combustion delay suppression configuration information, the preset fuel combustion consumption volume, the preset equipment performance coefficient, and the combustion rate,

[0094] The corresponding fuel radius is determined based on the fuel size parameters, and the total fuel volume is obtained based on the fuel radius;

[0095] The fuel combustion consumption volume is obtained based on the preset remaining fuel volume and the total fuel volume.

[0096] For example, determining the corresponding fuel radius based on the fuel size parameter and obtaining the complete fuel volume based on the fuel radius can be, but is not limited to, parsing the fuel size parameter to obtain the fuel radius (unit can be, but is not limited to, m) included in the fuel size parameter (if the fuel radius has already been determined in a previous step, it does not need to be determined again here), and then using an existing formula for the volume of a sphere (e.g., The complete fuel volume is calculated using R (where R is the fuel radius). Since fuel particles are relatively small, numerous, and uniform, they can be treated as spheres for calculation. The accuracy of the obtained parameters meets the requirements of practical situations. In relevant experiments, tests, and / or production operations, fuel particles are often treated as spheres for related calculations. The complete fuel volume can be, but is not limited to, the volume of fuel particles before combustion. It should be noted that the specific implementation method and related properties for determining the corresponding fuel radius based on the fuel size parameters and obtaining the complete fuel volume based on the fuel radius can be determined by those skilled in the art according to the actual situation. The above description is merely an example and does not constitute a limitation.

[0097] For example, the remaining fuel volume can be obtained by multiplying a preset combustion delay residual coefficient X by the fuel radius R to get the remaining fuel particle radius X·R at the end of the combustion delay, and then using an existing sphere volume formula (e.g.) The residual coefficient X is calculated based on actual physical laws, experimental conditions, and / or testing conditions. Its range is typically (0, 0.8], with a preferred value of 0.8. The residual fuel volume can be, but is not limited to, the volume of material remaining after the combustion delay ends; that is, it can be understood as the volume of particulate matter remaining after the radius of the fuel particles decreases from R to X·R due to combustion. It should be noted that the source, specific properties, and source and properties of the residual coefficient can be determined by those skilled in the art based on actual circumstances. The above description is merely illustrative and does not constitute a limitation.

[0098] For example, obtaining the fuel combustion consumption volume based on the preset remaining fuel volume and the total fuel volume can be, but is not limited to, subtracting the remaining fuel volume from the total fuel volume. It should be noted that the specific implementation of obtaining the fuel combustion consumption volume based on the preset remaining fuel volume and the total fuel volume can be determined by those skilled in the art according to actual circumstances; the above description is merely an example and does not constitute a limitation.

[0099] By taking the above steps, the relevant combustion principles can be considered in more detail, resulting in a more accurate fuel combustion consumption volume. This improves the overall accuracy of the calculation, thereby enhancing the accuracy of detecting whether the boiler combustion delay suppression configuration information is abnormal, and indirectly improving the effect of boiler combustion delay suppression.

[0100] In one alternative implementation, such as Figure 5As shown, the process of obtaining the predicted combustion delay time based on the fuel characteristic parameters corresponding to the combustion delay suppression configuration information, the preset fuel combustion consumption volume, the preset equipment performance coefficient, and the combustion rate includes the following steps:

[0101] S501: Based on the fuel characteristic parameters, determine the corresponding fuel density and fuel molecular weight.

[0102] S502: Based on the fuel combustion consumption volume, fuel density, and fuel molecular weight, obtain the cumulative amount of fuel consumed.

[0103] S503: Based on the equipment performance coefficient, the cumulative amount of fuel consumed, and the combustion rate, the predicted combustion delay time is obtained.

[0104] For example, step S501 may be, but is not limited to, parsing the fuel characteristic parameters to obtain the fuel characteristic parameters, including or corresponding fuel density (the unit may be, but is not limited to, kg / m³). 3 The fuel density and fuel molecular weight (units may be, but are not limited to, kg / kmol). The fuel density may be, but is not limited to, the physical density of the fuel, and the fuel molecular weight may be, but is not limited to, the relative molecular mass of the fuel molecule. The fuel density and fuel molecular weight can be obtained directly by consulting relevant chemical literature or configuration information. It should be noted that the specific implementation method of step S501, the source and properties of the fuel density and fuel molecular weight, etc., can be determined by those skilled in the art based on the actual situation. The above description is merely an example and does not constitute a limitation.

[0105] For example, step S502 can be, but is not limited to, multiplying the fuel combustion consumption volume by the fuel density and then dividing by the fuel molecular weight to obtain the cumulative amount of fuel consumed. The fuel combustion consumption volume can be expressed as, but is not limited to, […]. Where V represents the current fuel combustion consumption volume, ρ represents the current fuel density, and M represents the current fuel molecular weight. It should be noted that the specific implementation of step S502 can be determined by those skilled in the art based on actual circumstances; the above description is merely an example and does not constitute a limitation.

[0106] For example, the term "amount of substance" in the embodiments of the present invention is a professional physical quantity term in the fields of chemistry and physics.

[0107] For example, step S503 can be expressed as, but is not limited to, the following formula:

[0108]

[0109] in, This represents the current equipment performance coefficient (which may be related to, but is not limited to, equipment performance, and is specifically closely related to, but not limited to, the load, structure, components, type, and / or nature of the boiler equipment). K represents the current cumulative amount of fuel consumed. T T represents the current combustion rate. d This indicates the current predicted combustion delay time.

[0110] It should be noted that the specific implementation of step S503 and the nature of the device performance coefficient can be determined by those skilled in the art based on the actual situation. The above description is only an example and does not constitute a limitation.

[0111] Through the above steps, we can refine and synthesize relevant physical and chemical laws, boiler operating characteristics, and fuel-related features. By optimizing the calculation and processing methods and based on the refined analysis of various underlying characteristic parameters, we can significantly improve the accuracy of determining the predicted combustion delay time. This, in turn, significantly improves the accuracy of detecting whether the overall boiler combustion delay suppression configuration information is abnormal, and thus significantly improves the effect of boiler combustion delay suppression.

[0112] In an optional implementation, it further includes:

[0113] Before obtaining the predicted combustion delay time based on the fuel characteristic parameters corresponding to the combustion delay suppression configuration information, the preset fuel combustion consumption volume, the preset equipment performance coefficient, and the combustion rate,

[0114] The performance coefficient of the equipment is obtained based on the first historical measured combustion delay time, first historical fuel density, first historical fuel combustion consumption volume, first historical fuel molecular weight, and first historical combustion rate corresponding to the combustion delay suppression configuration information before the improvement.

[0115] For example, the improved combustion delay suppression configuration information can be, but is not limited to, the previous generation combustion delay suppression configuration information relative to the current delay suppression configuration information. Correspondingly, the current combustion delay suppression configuration information can be understood as, but is not limited to, the improved combustion delay suppression configuration information relative to the improved combustion delay suppression configuration information. In actual industrial applications, the combustion delay suppression schemes corresponding to the combustion delay suppression configuration information can be continuously improved; therefore, the combustion delay suppression configuration information also continuously improves accordingly. Correspondingly, determining whether the combustion delay suppression configuration information is abnormal can also be, but is not limited to, determining whether the degree of improvement of the combustion delay suppression scheme meets expectations. It should be noted that the nature and related relationships of the improved combustion delay suppression configuration information can be determined by those skilled in the art based on the actual situation. The above description is merely an example and does not constitute a limitation.

[0116] Preferably, the current combustion delay suppression configuration information and the previous combustion delay suppression configuration information can be compared to determine whether the current combustion delay suppression configuration information involves improvements to the equipment configuration. If not, the equipment performance coefficient can be obtained based on the first historical measured combustion delay time, first historical fuel density, first historical fuel combustion consumption volume, first historical fuel molecular weight, and first historical combustion rate corresponding to the previous combustion delay suppression configuration information. This approach fully considers the relationship between the equipment performance coefficient and the equipment configuration. When it is determined that the equipment condition has not changed significantly, the equipment performance coefficient can be calculated based on the relevant measured parameters corresponding to the previous combustion delay suppression configuration information. This improves the accuracy and convenience of determining the equipment performance coefficient.

[0117] For example, some parameters in the embodiments of the present invention that are named starting with "first history" can be directly measured and obtained by means of laboratory testing and / or actual furnace testing of boiler equipment operating conditions based on the previous combustion delay suppression scheme corresponding to the previous combustion delay suppression configuration information, but not limited to, or obtained based on relevant configuration information such as the previous laboratory test and / or actual furnace test.

[0118] For example, the first historical measured combustion delay time can be directly measured and obtained through laboratory testing and / or actual furnace testing of boiler equipment operating conditions based on the improved combustion delay suppression scheme corresponding to the improved combustion delay suppression configuration information, but not limited to the improved combustion delay suppression scheme configuration information. The corresponding first historical fuel density and first historical fuel molecular weight can be directly obtained through methods such as consulting relevant materials, records, or configuration information. Specifically, their nature can be, but is not limited to, the fuel density and fuel molecular weight involved in the relevant experimental testing operations when obtaining the first historical measured combustion delay time. It should be noted that the specific sources of the first historical measured combustion delay time, first historical fuel density, and first historical combustion molecular weight can be determined by those skilled in the art based on the actual situation. The above description is merely an example and does not constitute a limitation.

[0119] For example, the device performance coefficient obtained based on the first historical measured combustion delay time, first historical fuel density, first historical fuel combustion consumption volume, first historical fuel molecular weight, and first historical combustion rate corresponding to the original combustion delay suppression configuration information can be expressed as, but is not limited to, the following formula:

[0120]

[0121] in, T represents the coefficient of performance of the equipment. d1The first historical measured combustion delay time is represented by V1, the first historical fuel combustion consumption volume is represented by ρ1, the first historical fuel density is represented by M1, and the first historical fuel molecular weight is represented by K. T1 This represents the first historical combustion rate. In the above steps, calculating the equipment performance coefficient can also be understood as, but is not limited to, substituting the relevant measured parameters corresponding to the combustion delay suppression configuration information before the improvement into a formula similar to step S503, and then performing a reverse calculation to obtain the equipment performance coefficient.

[0122] It should be noted that the specific implementation method for obtaining the equipment performance coefficient based on the first historical measured combustion delay time, first historical fuel density, first historical fuel combustion consumption volume, first historical fuel molecular weight and first historical combustion rate corresponding to the combustion delay suppression configuration information before the improvement can be determined by those skilled in the art according to the actual situation. The above description is only an example and does not constitute a limitation.

[0123] For example, the equipment performance coefficient is closely related to the equipment configuration. Therefore, the determined equipment performance coefficient needs to correspond to the equipment operating conditions corresponding to the current measured combustion delay time. This will help improve the accuracy of determining the current predicted combustion delay time.

[0124] Through the above steps, when the current combustion delay suppression configuration information does not involve improvements to the equipment configuration, the corresponding equipment performance coefficient can be determined directly based on the specific measured physical and chemical parameters under the corresponding operating conditions of the historical combustion delay suppression configuration information before the improvement. This ensures that the equipment performance coefficient accurately matches the corresponding boiler equipment performance conditions under the current circumstances, thereby indirectly improving the overall accuracy of detecting whether the boiler combustion delay suppression configuration information is abnormal, and thus indirectly improving the effect of boiler combustion delay suppression.

[0125] In an optional implementation, it further includes:

[0126] Before obtaining the equipment performance coefficient based on the first historical measured combustion delay time, first historical fuel density, first historical fuel combustion consumption volume, first historical fuel molecular weight, and first historical combustion rate corresponding to the original combustion delay suppression configuration information,...

[0127] Based on the first historical fuel radius corresponding to the improved combustion delay suppression configuration information, the first historical complete fuel volume is obtained; based on the preset first historical remaining fuel volume and the first historical complete fuel volume, the first historical fuel combustion consumption volume is obtained.

[0128] For example, the nature and source of the first historical fuel radius, the first historical full fuel volume, and the first historical remaining fuel volume can be referred to the description of the nature and source of the full fuel volume and fuel radius in the embodiments of the present invention, and will not be repeated here.

[0129] For example, the first historical complete fuel volume is obtained based on the first historical fuel radius corresponding to the improved combustion delay suppression configuration information; the specific principle of obtaining the first historical fuel combustion consumption volume based on the preset first historical remaining fuel volume and the first historical complete fuel volume can be found in the description of the steps in the embodiments of the present invention for determining the corresponding fuel radius based on the fuel size parameter and obtaining the complete fuel volume based on the fuel radius; and obtaining the fuel combustion consumption volume based on the preset remaining fuel volume and the complete fuel volume, which will not be repeated here.

[0130] Through the above steps, the relevant combustion principles can be considered in more detail, and the measured fuel consumption volume corresponding to the working conditions of the combustion delay suppression configuration information before the improvement can be obtained more accurately. This improves the accuracy of determining the equipment performance coefficient, thereby improving the accuracy of detecting whether the overall boiler combustion delay suppression configuration information is abnormal, and thus indirectly improving the effect of boiler combustion delay suppression.

[0131] In an optional implementation, it further includes:

[0132] Before obtaining the equipment performance coefficient based on the first historical measured combustion delay time, first historical fuel density, first historical fuel combustion consumption volume, first historical fuel molecular weight, and first historical combustion rate corresponding to the original combustion delay suppression configuration information,...

[0133] The first historical combustion rate is obtained based on the first historical reaction gas phase temperature, first historical particulate phase temperature, first historical pre-exponential factor, first historical reaction activation energy, and first historical fuel radius corresponding to the improved combustion delay suppression configuration information.

[0134] For example, the properties and sources of the first historical reaction gas phase temperature, the first historical particulate phase temperature, the first historical pre-exponential factor, the first historical reaction activation energy, and the first historical fuel radius can be referred to the description of the properties and sources of the reaction gas phase temperature, particulate phase temperature, pre-exponential factor, reaction activation energy, and fuel radius in the embodiments of the present invention, and will not be repeated here.

[0135] For example, the specific principle of obtaining the first historical combustion rate based on the first historical reaction gas phase temperature, first historical particulate phase temperature, first historical pre-exponential factor, first historical reaction activation energy, and first historical fuel radius corresponding to the improved combustion delay suppression configuration information can be found in the description of step S404 in the embodiments of the present invention, and will not be repeated here.

[0136] Through the above steps, based on the relevant principles and laws of chemical reaction kinetics and by fully analyzing the relevant parameters, and using more detailed physicochemical indicators as input, the corresponding first historical combustion rate can be determined more accurately. This improves the accuracy of determining the equipment performance coefficient, thereby improving the accuracy of detecting whether the overall boiler combustion delay suppression configuration information is abnormal, and indirectly improving the effect of boiler combustion delay suppression.

[0137] In an optional implementation, it further includes:

[0138] Before obtaining the predicted combustion delay time based on the fuel characteristic parameters corresponding to the combustion delay suppression configuration information, the preset fuel combustion consumption volume, the preset equipment performance coefficient, and the combustion rate,

[0139] The performance coefficient of the equipment is obtained based on the second historical measured combustion delay time, second historical fuel density, second historical fuel combustion consumption volume, second historical fuel molecular weight and second historical combustion rate corresponding to the combustion delay suppression configuration information.

[0140] Preferably, the current combustion delay suppression configuration information and the previous combustion delay suppression configuration information can be compared to determine whether the current combustion delay suppression configuration information involves improvements to the equipment configuration. If so, the equipment performance coefficient can be obtained based on the second historical measured combustion delay time, second historical fuel density, second historical fuel combustion consumption volume, second historical fuel molecular weight, and second historical combustion rate corresponding to the combustion delay suppression configuration information. This approach fully considers the relationship between the equipment performance coefficient and the equipment configuration. When a significant change in the equipment condition is determined, the equipment performance coefficient can be calculated based on relevant measured parameters from other measured operating operations (which may include, but are not limited to, other actual furnace tests or laboratory tests) corresponding to the current combustion delay suppression configuration information. This improves the accuracy and convenience of determining the equipment performance coefficient.

[0141] For example, some parameters in the embodiments of the present invention that begin with "Second History" can be directly measured and obtained through laboratory tests and / or actual furnace tests on boiler equipment operating conditions corresponding to the current combustion delay suppression scheme, but not limited to the current combustion delay suppression configuration information. Alternatively, they can be obtained based on relevant configuration information from such laboratory tests and / or actual furnace tests. The origin of parameters beginning with "Second History" can be, but is not limited to, other past measured operating operations (such as other laboratory tests and / or actual furnace tests) under the current boiler equipment operating conditions corresponding to the combustion delay suppression scheme. For example, under the current boiler equipment operating conditions corresponding to the combustion delay suppression scheme, the current measured combustion delay time, fuel density, fuel combustion consumption volume, fuel molecular weight, and combustion rate parameters originate from a current actual furnace test / laboratory test / production operation. Here, it is represented as measured operation A. Under the same boiler equipment operating conditions, the second historical measured combustion delay time, second historical fuel density, second historical fuel combustion consumption volume, second historical fuel molecular weight, and second historical combustion rate can be derived from, but are not limited to, another past furnace test / laboratory test / production operation. This other past furnace test / laboratory test / production operation is represented here as measured operation B. B and A are obviously not the same measured operation, and the time points are also different. The measured operating conditions (excluding conditions related to boiler equipment) corresponding to A and B can also be different to some extent or completely. For example, the measured combustion delay time and the second measured combustion delay time can be different, the fuel density and the second historical fuel density can be different, and the fuel combustion consumption volume and the second historical fuel combustion consumption volume can be different, etc. However, since the specific conditions of the boiler equipment corresponding to A and B are the same, it is reasonable to use the relevant parameters corresponding to B to estimate the current equipment performance coefficient. It should be noted that the properties related to the "second history" can be determined by those skilled in the art based on the actual situation. The above description is only an example and does not constitute a limitation.

[0142] For example, the second historical measured combustion delay time can be directly measured and obtained through laboratory testing and / or actual furnace testing under the boiler equipment operating conditions of the current combustion delay suppression scheme corresponding to the current combustion delay suppression configuration information, but not limited to the current combustion delay suppression configuration information. The corresponding second historical fuel density and second historical fuel molecular weight can be directly obtained through methods such as consulting relevant data, records, or configuration information. Specifically, their nature can be, but is not limited to, the fuel density and fuel molecular weight involved in the experimental testing and other operations involved in obtaining the second historical measured combustion delay time. It should be noted that the specific sources of the second historical measured combustion delay time, second historical fuel density, and second historical combustion molecular weight can be determined by those skilled in the art based on the actual situation. The above description is merely an example and does not constitute a limitation.

[0143] For example, the device performance coefficient obtained based on the second historical measured combustion delay time, second historical fuel density, second historical fuel combustion consumption volume, second historical fuel molecular weight, and second historical combustion rate corresponding to the combustion delay suppression configuration information can be expressed as, but is not limited to, the following formula:

[0144]

[0145] in, T represents the coefficient of performance of the equipment. d2 The second historical measured combustion delay time is represented by V2, the second historical fuel combustion consumption volume is represented by ρ2, the second historical fuel density is represented by M2, and the second historical fuel molecular weight is represented by K. T2 This represents the second historical combustion rate. In the above steps, calculating the equipment performance coefficient can also be understood as, but is not limited to, substituting the relevant measured parameters of the historical measured operation corresponding to the current combustion delay suppression configuration information into a formula similar to step S503, and then performing a reverse calculation to obtain the equipment performance coefficient.

[0146] It should be noted that the specific implementation method for obtaining the equipment performance coefficient based on the second historical measured combustion delay time, second historical fuel density, second historical fuel combustion consumption volume, second historical fuel molecular weight and second historical combustion rate corresponding to the combustion delay suppression configuration information can be determined by those skilled in the art according to the actual situation. The above description is only an example and does not constitute a limitation.

[0147] For example, the equipment performance coefficient is closely related to the equipment configuration. Therefore, the determined equipment performance coefficient needs to correspond to the equipment operating condition corresponding to the current measured combustion delay time. In this case, the corresponding improvement involves the improvement of the equipment configuration, which leads to a change in the nature of the equipment operating condition. Therefore, it is necessary to use relevant historical parameters under the current equipment operating condition configuration to determine the equipment performance coefficient. This will help improve the accuracy of determining the current predicted combustion delay time.

[0148] Through the above steps, when the current combustion delay suppression configuration information involves improvements to the equipment configuration, the corresponding equipment performance coefficient can be determined based on the specific measured physical parameters in other historical measured operation processes under the corresponding operating conditions of the current (improved) historical combustion delay suppression configuration information. This ensures that the equipment performance coefficient accurately matches the corresponding boiler equipment performance conditions under the current circumstances, thereby indirectly improving the overall accuracy of detecting whether the boiler combustion delay suppression configuration information is abnormal, and thus indirectly improving the effect of boiler combustion delay suppression.

[0149] In an optional implementation, it further includes:

[0150] Before obtaining the equipment performance coefficient based on the second historical measured combustion delay time, second historical fuel density, second historical fuel combustion consumption volume, second historical fuel molecular weight, and second historical combustion rate corresponding to the combustion delay suppression configuration information.

[0151] Based on the second historical fuel radius corresponding to the combustion delay suppression configuration information, the second historical complete fuel volume is obtained; based on the preset second historical remaining fuel volume and the second historical complete fuel volume, the second historical fuel combustion consumption volume is obtained.

[0152] For example, the nature and source of the second historical fuel radius, the second historical full fuel volume, and the second historical remaining fuel volume can be referred to the description of the nature and source of the fuel radius in the embodiments of the present invention, and will not be repeated here.

[0153] For example, the second historical complete fuel volume is obtained based on the second historical fuel radius corresponding to the combustion delay suppression configuration information; the specific principle of obtaining the second historical fuel combustion consumption volume based on the preset second historical remaining fuel volume and the second historical complete fuel volume can be found in the description of the steps in the embodiments of the present invention for determining the corresponding fuel radius based on the fuel size parameter and obtaining the complete fuel volume based on the fuel radius; and obtaining the fuel combustion consumption volume based on the preset remaining fuel volume and the complete fuel volume, which will not be repeated here.

[0154] By taking the above steps, the relevant combustion principles can be considered in more detail, and the fuel consumption volume corresponding to other historical measured processes under the current combustion delay suppression configuration information can be obtained more accurately. This improves the accuracy of determining the equipment performance coefficient, thereby improving the overall accuracy of detecting whether the boiler combustion delay suppression configuration information is abnormal, and thus indirectly improving the effect of boiler combustion delay suppression.

[0155] In an optional implementation, it further includes:

[0156] Before obtaining the equipment performance coefficient based on the second historical measured combustion delay time, second historical fuel density, second historical fuel combustion consumption volume, second historical fuel molecular weight, and second historical combustion rate corresponding to the combustion delay suppression configuration information.

[0157] The second historical combustion rate is obtained based on the second historical reaction gas phase temperature, second historical particulate phase temperature, second historical pre-exponential factor, second historical reaction activation energy, and second historical fuel radius corresponding to the combustion delay suppression configuration information.

[0158] For example, the properties and sources of the second historical reaction gas phase temperature, the second historical particulate phase temperature, the second historical pre-exponential factor, the second historical reaction activation energy, and the second historical fuel radius can be referred to the description of the properties and sources of the reaction gas phase temperature, particulate phase temperature, pre-exponential factor, reaction activation energy, and fuel radius in the embodiments of the present invention, and will not be repeated here.

[0159] For example, the specific principle of obtaining the second historical combustion rate based on the second historical reaction gas phase temperature, second historical particulate phase temperature, second historical pre-exponential factor, second historical reaction activation energy, and second historical fuel radius corresponding to the combustion delay suppression configuration information can be referred to the description of step S404 in the embodiments of the present invention, and will not be repeated here.

[0160] Through the above steps, based on the relevant principles and laws of chemical reaction kinetics and by fully analyzing the relevant parameters, and using more detailed physicochemical indicators as input, the corresponding second historical combustion rate can be determined more accurately. This improves the accuracy of determining the equipment performance coefficient, thereby improving the accuracy of detecting whether the overall boiler combustion delay suppression configuration information is abnormal, and indirectly improving the effect of boiler combustion delay suppression.

[0161] In an optional implementation, determining whether the combustion delay suppression configuration information is abnormal based on the measured combustion delay time and the predicted combustion delay time includes:

[0162] Determine whether the conditions are met: the measured combustion delay time is greater than the predicted combustion delay time and the difference between the measured combustion delay time and the predicted combustion delay time is greater than a preset deviation threshold. If not, configure boiler combustion and start boiler combustion based on the combustion delay suppression configuration information.

[0163] For example, the deviation threshold can be, but is not limited to, a value equivalent to, the predicted combustion delay time. That is, it can be considered, but is not limited to, that if the measured combustion delay time is more than twice the predicted combustion delay time, it is abnormal. It should be noted that the specific value of the deviation threshold can be determined by those skilled in the art based on the actual situation. The above description is merely an example and does not constitute a limitation.

[0164] Through the above steps, based on the principles of fault tolerance and error, and with more detailed standards and indicators, it is possible to more accurately determine whether the actual suppression effect of the suppression scheme corresponding to the combustion delay suppression configuration information matches the corresponding expectations. This can further improve the accuracy of detecting whether the boiler combustion delay suppression configuration information is abnormal, and more accurately apply the corresponding suppression scheme only when the boiler combustion delay suppression configuration information is not abnormal and matches the corresponding expectations, thereby further improving the effect of boiler combustion delay suppression.

[0165] In an optional implementation, it further includes:

[0166] A first alarm is triggered when it is determined that the measured combustion delay time is greater than the predicted combustion delay time and the difference between the measured combustion delay time and the predicted combustion delay time is greater than a preset deviation threshold.

[0167] For example, issuing the first alarm can be, but is not limited to, sending or displaying an alarm message to the staff, such as "The current combustion delay suppression scheme still needs further improvement; please take appropriate improvement measures in a timely manner." After receiving the first alarm, the relevant staff can take improvement actions on the corresponding suppression scheme and its corresponding configuration information, such as eliminating defects in the suppression scheme and optimizing the scheme's operating conditions (e.g., combustion temperature optimization, equipment improvement, etc.), until the combustion delay suppression configuration information is no longer abnormal. It should be noted that the specific implementation method of the first alarm, the improvement method of the combustion delay suppression scheme, and the specific reaction behavior after receiving the first alarm can be determined by those skilled in the art based on the actual situation. The above description is only an example and does not constitute a limitation.

[0168] By following the steps above, relevant personnel can be promptly notified when there are abnormalities in the boiler combustion delay suppression configuration information, which facilitates corresponding improvements to the combustion delay suppression scheme and indirectly improves the overall efficiency and effectiveness of combustion delay suppression.

[0169] In an optional implementation, it further includes:

[0170] Determine whether the condition that both the predicted combustion delay time and the actual combustion delay time are less than the first historical actual combustion delay time is met. If not, issue a second alarm.

[0171] For example, the second alarm may be, but is not limited to, sending or displaying an alarm message to the staff, such as "The current combustion delay suppression scheme has degraded in effectiveness compared to the previous one. The current delay suppression scheme has significant problems; please pay attention and make timely adjustments." After receiving the second alarm, the relevant staff may also take improvement actions on the corresponding suppression scheme and its corresponding configuration information, such as eliminating the defects of the suppression scheme and optimizing the scheme's operating conditions (e.g., optimizing combustion temperature, improving equipment, etc.). It should be noted that the specific implementation method of the second alarm, the improvement method of the combustion delay suppression scheme, and the specific response behavior after receiving the second alarm can be determined by those skilled in the art based on the actual situation. The above description is only an example and does not constitute a limitation.

[0172] By following the steps above, the comprehensiveness of anomaly detection for combustion delay suppression schemes can be improved, making it easier to detect anomalies in the schemes more accurately. This facilitates corresponding improvements to the combustion delay suppression schemes, thereby indirectly improving the overall efficiency and effectiveness of combustion delay suppression.

[0173] Preferably, if both the predicted combustion delay time and the measured combustion delay time are less than the first historical measured combustion delay time, the predicted combustion delay time can be subtracted from the first historical measured combustion delay time to obtain a predicted improvement coefficient; and the measured combustion delay time can be subtracted from the first historical measured combustion delay time to obtain a measured improvement coefficient. Then, the predicted improvement coefficient and the measured improvement coefficient can be sent to the relevant staff as reference information for optimizing the relevant combustion delay suppression scheme. This allows staff to more intuitively, clearly and comprehensively understand the improvement of the improved combustion delay suppression scheme compared to the original combustion delay suppression scheme, thereby improving the efficiency of relevant research and analysis.
