Description

Technical Field

[0001] This invention relates to boiler control methods, and more specifically to a method, apparatus, computer equipment, and storage medium for collaborative control of multiple boiler intelligent agents. Background Technology

[0002] Currently, most boiler rooms in China are equipped with multiple boilers. Users can replace the previous model of fewer, higher-investment, larger-tonnage boilers with a flexible combination of multiple small-tonnage boilers, achieving flexible changes in output load, while maintaining the same total investment. However, this places higher demands on the boiler room control technology. Boiler room control systems are no longer limited to traditional boiler control but have gradually evolved to treat the entire boiler room as a whole, scheduling and controlling boiler operation from a global perspective.

[0003] Existing control technologies for multiple boilers primarily employ boiler group control, which has two core control mechanisms: first, boiler rotation control to ensure balanced operation across multiple boilers; and second, controlling the number of operating boilers based on the overall load demand of the boiler room to meet load requirements. However, with increasing energy constraints and the need for further energy savings in boiler room operations, the drawbacks of the existing group control method have become increasingly apparent. The cluster control algorithm for multiple boilers is relatively crude, and individual boiler control still relies on simple start-stop and traditional PID regulation. The lack of effective integration among the multiple boilers has become a bottleneck for the efficient operation of boiler room group control systems.

[0004] Therefore, it is necessary to design a new method that allows boilers of different tonnages to participate in coordinated control simultaneously, thereby significantly reducing the number of frequent start-ups and shutdowns, reducing energy consumption, making boiler operation more precise, and effectively solving the difference between output load and actual demand. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method, device, computer equipment and storage medium for collaborative control of multiple boiler intelligent agents.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-boiler intelligent agent cooperative control method, comprising:

[0007] All boilers in the boiler room are coded and sorted to obtain a boiler coding table;

[0008] The sorted boilers are controlled by a single pointer polling sequence control method.

[0009] Determine whether the number of boilers involved in operation is equal to zero;

[0010] If the number of boilers involved in operation is zero, then determine whether the boiler margin that needs to be coordinated and controlled is not zero.

[0011] If the boiler margin that needs to be coordinated and controlled is not equal to zero, then the boiler that the pointer points to is started, and the individual boiler is adjusted and controlled to increase or decrease the load according to the target load adjustment amount.

[0012] If the number of boilers involved in operation is not zero, then select the combination with the best efficiency while meeting the current demand load.

[0013] The load regulation and control of the boiler is carried out based on the algorithm of secondary load distribution combined with the main control mode of the ignition boiler.

[0014] The further technical solution is as follows: the sorting control of the sorted boilers through single-pointer polling sequence control includes:

[0015] The pointer is moved to the beginning of the boiler coding table. According to the control conditions, the pointer count is increased, and the size of the element pointed to by the pointer and the target element are compared one by one. If the pointer is not less than the total number of boilers, then one cycle ends.

[0016] Its further technical solution is as follows: the algorithm based on secondary load distribution combined with the main control mode of the ignition boiler performs load regulation control on the regulated boiler, including:

[0017] Determine if the number of boilers involved in operation is greater than zero;

[0018] If the number of boilers involved in operation is greater than zero, then the boilers under control will be subject to load increase coordination control.

[0019] The further technical solution is as follows: the load increase coordinated control of the regulated boiler includes:

[0020] Start the boiler controlled by the pointer and operate it at full load.

[0021] When the current boiler is at full load, the pointer increments by one, and the boiler units pointed to by the pointer are started to run at full load in sequence. The number of boilers participating in operation is decremented by one, and the decremented value of the number of boilers participating in operation is increased in turn until the number of boilers participating in operation is equal to zero. When the last boiler is started, the currently started boiler automatically follows the coordinated control margin to perform automatic load adjustment control.

[0022] After the load increase allocation is completed, the boilers involved in load regulation are optimized and adjusted, and the load is redistributed a second time based on the boiler operating curve.

[0023] The further technical solution is as follows: after determining whether the number of boilers participating in operation is greater than zero, it also includes:

[0024] If the number of boilers involved in operation is not greater than zero, then load reduction and coordinated control will be implemented for the boilers under control.

[0025] The further technical solution is as follows: the load reduction and coordinated control of the regulated boiler includes:

[0026] Following the principle of first-to-start and first-to-stop, the pointer increments, and the load is reduced sequentially to shut down the furnaces one by one.

[0027] When the load reduction allocation is completed, if the number of operating boilers is greater than 1, the optimization and adjustment will be carried out according to the principle of secondary redistribution; when the load reduction allocation is completed and the number of operating boilers is 1, the boiler pointed to by the pointer will reduce its load according to the target load until it is reduced to the minimum load, and the fire source will be retained. When the load reduction of the currently controlled boiler reaches the set value, the fire source boiler will take the main control.

[0028] The present invention also provides a multi-boiler intelligent agent collaborative control device, comprising:

[0029] The coding and sorting unit is used to code and sort all the boilers in the boiler room to obtain a boiler coding table;

[0030] A single-pointer control unit is used to control the sorted boilers by means of a single-pointer polling sequence control method;

[0031] The first judgment unit is used to determine whether the number of boilers participating in operation is equal to zero.

[0032] The second judgment unit is used to determine whether the boiler margin that needs to be coordinated and controlled is not equal to zero if the number of boilers participating in operation is equal to zero.

[0033] The adjustment and control unit is used to start the boiler pointed to by the pointer if the boiler margin to be coordinated and controlled is not equal to zero, and the individual boiler adjusts and controls the load by adding and subtracting according to the target load adjustment amount.

[0034] The combination selection unit is used to select the combination with the best efficiency if the number of boilers participating in operation is not zero, while meeting the current demand load.

[0035] The load adjustment unit is used to adjust and control the load of the boiler under control based on the algorithm of secondary load distribution combined with the main control mode of the pilot boiler.

[0036] The present invention also provides a computer device, the computer device including a memory and a processor, the memory storing a computer program, and the processor executing the computer program to implement the above-described method.

[0037] The present invention also provides a storage medium storing a computer program that, when executed by a processor, implements the above-described method.

[0038] The beneficial effects of this invention compared with the prior art are as follows: This invention encodes and sorts all boilers, and then uses a single-pointer polling sequential control method for control. It combines the number of boilers participating in operation with the spare capacity of boilers that need to be coordinated for load regulation control. Furthermore, based on a secondary load allocation algorithm combined with the main control method of the pilot boiler, it performs load regulation control on the regulated boilers, enabling boilers of different tonnages to participate in coordinated control simultaneously. This significantly reduces the number of frequent start-ups and shutdowns of the boilers, reduces energy consumption, makes boiler operation more precise, and effectively solves the difference between output load and actual demand.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0054] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0055] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram illustrating an application scenario of the multi-boiler intelligent agent collaborative control method provided in an embodiment of the present invention. Figure 2This is a schematic flowchart illustrating the multi-boiler intelligent agent collaborative control method provided in an embodiment of the present invention. This method is applied in a server. The server connects to individual boilers via an industrial IoT gateway. The IoT gateway is equipped with RS485 and TCP / IP interfaces, enabling connections to up to 16 individual boilers to form a local area network within the boiler room. The system uses the industrially standard MODBUS-RTU protocol for information exchange. Individual boilers all use the same protocol and are coded according to the boiler room's process settings, allowing boilers of different tonnages to participate in collaborative control simultaneously. This significantly reduces the frequency of boiler start-ups and shutdowns, lowers energy consumption, and makes boiler operation more precise, effectively resolving the discrepancy between output load and actual demand.

[0056] In this embodiment, for the control process of multiple boilers, it is necessary to calculate the load target. Specifically, the rated total load is calculated as follows:

[0057] Treating all boilers in the boiler room as a whole, that is, equivalent to a large-tonnage boiler, the total design load of the boiler room is calculated as follows: Ded=Ded(1)+Ded(2)+···+Ded(n) (n≤16); Ded(i): rated evaporation capacity of the boiler.

[0058] The actual load of a single boiler is calculated as follows: Where Dsj(i): boiler unit load; Bfk(i): boiler combustion feedback; Bmin(i): boiler minimum allowable load feedback.

[0059] The actual total load is calculated as follows: Dsj=Dsj(1)+Dsj(2)+···+Dsj(n) (n≤16);

[0060] The allowable load adjustment is calculated as: ΔD = Ded - Dsj

[0061] The conventional incremental PID calculation yields the incremental value of the total load that the system must provide: the incremental value output u(k) = u(k-1) + Δu(k), Δu(k) = Kp*e() + Ki*e(-1) + Kd*e(-2), where Kp, Ki, and Kd are the coefficients of the conventional PID after the calculation and variation.

[0062] The target load adjustment is calculated as follows:

[0063] Given the boiler operating characteristic curve (lower load, lower combustion efficiency; higher load, higher combustion efficiency; and higher energy consumption during boiler start-up and shutdown), the algorithm is designed to reduce the frequency of start-up and shutdown and operate at full load as much as possible.

[0064] The target load adjustment amount is calculated as follows:

[0065] The calculation of the number of boilers to be operated (assuming that the rated evaporation capacity of all boilers in the boiler room is the same) is required: q = INT[D(k) / (Ded(i)]; The calculation of the boiler margin for coordinated control is: r = D(k) - q * Ded(i), where Ded(i): the rated evaporation capacity of the boiler.

[0066] Figure 2 This is a flowchart illustrating the multi-boiler intelligent agent collaborative control method provided in an embodiment of the present invention. Figure 2 As shown, the method includes the following steps S110 to S170.

[0067] S110. Code and sort all boilers in the boiler room to obtain a boiler coding table.

[0068] In this embodiment, the boiler coding table refers to a table formed by coding and sorting all the boilers in the boiler room.

[0069] Specifically, before adjusting the total load of the boiler room, in order to achieve orderly control of the boilers, we first sort the boilers. Since it is uncertain whether the boilers are in a fault or maintenance state during operation, this condition is not considered in the initial sorting process. All boilers in the boiler room are uniformly coded and sorted.

[0070] S120. The sorted boilers are controlled by a single pointer polling sequence control method.

[0071] In this embodiment, the pointer is set to the starting position of the boiler coding table. According to the control conditions, the pointer count increases, and the size of the element pointed to by the pointer and the target element are compared one by one. If the pointer is not less than the total number of boilers, then one cycle ends.

[0072] Boiler sequencing control is performed using a single pointer, as detailed below:

[0073] Pointer i: Boiler unit pointer;

[0074] Set pointer i to the beginning of the boiler coding table and perform the following loop operation:

[0075] Based on the control conditions, the pointer i gradually increases and the size of the element pointed to by i is compared with the target element one by one; if i ≥ n, then a loop ends; the pointer i runs independently and does not interfere with each other.

[0076] By employing boiler coding (with built-in boiler parameters) and single-pointer sequential control, boiler activation becomes more targeted.

[0077] S130. Determine whether the number of boilers involved in operation is equal to zero;

[0078] S140. If the number of boilers participating in operation is zero, then determine whether the boiler margin that needs to be coordinated and controlled is not zero.

[0079] S150. If the boiler margin that needs to be coordinated and controlled is not equal to zero, then start the boiler that the pointer points to and controls, and the individual boiler will adjust and control the load by increasing and decreasing the load according to the target load adjustment amount.

[0080] In this embodiment, when q = 0 and r ≠ 0, r = D(k); the boiler unit pointed to by pointer i is started. This boiler unit represents the boiler that needs to be coordinated and controlled, and the individual boiler automatically follows the target load adjustment amount D(k) to perform automatic load adjustment and control.

[0081] If the boiler margin requiring coordinated control is zero, then proceed to step S120.

[0082] S160. If the number of boilers participating in operation is not zero, then select the combination with the best efficiency while meeting the current demand load.

[0083] In this embodiment, when q≠0, considering that most oil and gas boilers in actual boiler rooms are manufactured by the same company, and their manufacturing processes, burners, water pumps, and other key equipment are basically the same, their combustion efficiencies are approximately equal. Therefore, when two or more boilers are operating in tandem, the optimal efficiency combination is selected while meeting the current load demand. Factors affecting boiler unit efficiency mainly include: a comprehensive judgment based on boiler unit capacity, boiler operating time, boiler start-up and shutdown frequency, and boiler operating curves.

[0084] S170. The load regulation and control of the boiler is carried out by combining the algorithm of secondary load distribution with the main control mode of the ignition boiler.

[0085] In one embodiment, please refer to Figure 3 The above-mentioned step S170 may include steps S171 to S173.

[0086] S171. Determine whether the number of boilers involved in operation is greater than zero;

[0087] S172. If the number of boilers involved in operation is greater than zero, then load increase coordination control will be implemented for the boilers under control.

[0088] In one embodiment, please refer to Figure 4 The above step S172 may include steps S1721 to S1723.

[0089] S1721. Start the boiler controlled by the pointer and run it at full load.

[0090] S1722. When the current boiler is at full load, the pointer is incremented by one, and the boiler units pointed to by the pointer are started to run at full load in sequence. The number of boilers participating in operation is decremented by one, and the decremented value of the number of boilers participating in operation is increased in sequence until the number of boilers participating in operation is equal to zero. When the last boiler is started, the currently started boiler automatically follows the coordinated control margin to perform automatic load adjustment control.

[0091] S1723. After the load increase distribution is completed, the boilers involved in load regulation are optimized and adjusted, and the load is redistributed a second time according to the boiler operation curve.

[0092] In this embodiment, when q > 0, the specific process of boiler load increase coordinated control is as follows:

[0093] The boiler unit pointed to by pointer i is started and put into operation, and then subjected to full-load regulation operation.

[0094] When the current boiler is at full load, the pointer p(i) is incremented by 1 and the boiler unit it points to is started sequentially and runs at full load. At the same time, the number of boilers started q is decremented by 1, and so on, until q = 0.

[0095] Once the last boiler is started, the currently started boiler will automatically follow the coordinated control margin r to perform automatic load adjustment control.

[0096] After the load increase allocation is completed, the system optimizes and adjusts the boilers involved in load regulation. Based on the boiler operating curve and taking into account the boiler efficiency, the system enables the more efficient boilers to take on more load increments and redistributes the load.

[0097] Specifically, the secondary load redistribution involves fine-tuning the boilers after the initial allocation. First, during boiler initialization coding, each boiler's capacity, combustion efficiency (based on factory data and judged by the boiler operator's experience through table lookup), operating time, and number of boiler start-ups and shutdowns are recorded. Second, after the initial load allocation, a table lookup is used to determine if the operating efficiency of multiple boilers is optimal. If not, a secondary allocation adjustment is performed according to the following principles: For boilers of the same tonnage, adjustments are made based on higher combustion efficiency and relatively shorter operating time. For example, if the current main control boiler's operating efficiency is higher than the others... When a boiler is already operating at full load, the main control boiler will operate at high load according to the principle of selection. The boiler with the lowest combustion efficiency will be used as the main control boiler (the original main control boiler will remain as the pilot boiler). For boilers of different tonnages, when the main control boiler is a large-tonnage boiler, it is determined whether the output power of the small-tonnage boiler and the output power of the large-tonnage boiler meet the requirements for high-load operation of the large-tonnage boiler. If they do, the large-tonnage boiler will operate at high load, and the small-tonnage boiler will be used as a fine-tuning boiler. The principle for determining high load is determined by the boiler operation curve.

[0098] In this embodiment, the secondary load allocation algorithm makes the boiler operation more precise and effectively solves the difference between the output load and the actual demand.

[0099] S173. If the number of boilers involved in operation is not greater than zero, then load reduction and coordinated control shall be implemented for the boilers under control.

[0100] In one embodiment, please refer to Figure 5 The above step S173 may include steps S1731 to S1732.

[0101] S1731. Following the principle of first-to-start and first-to-stop, the pointer increments and the load is reduced sequentially to shut down the furnaces one by one.

[0102] S1732. When the load reduction allocation is completed and the number of operating boilers is greater than 1, the optimization and adjustment shall be carried out according to the principle of secondary redistribution. When the load reduction allocation is completed and the number of operating boilers is 1, the boiler to which the pointer is pointing shall reduce its load according to the target load until it is reduced to the minimum load, and the fire source shall be retained. When the load reduction of the currently controlled boiler reaches the set value, the fire source boiler shall be the main control.

[0103] Specifically, when q < 0, the boiler load reduction coordinated control is as follows:

[0104] The boiler unit pointed to by the boiler unit pointer i will have its load reduced first according to the principle of first-to-first-to-stop. The pointer i will increment and the load will be reduced sequentially until the boiler is shut down. After the load reduction is completed, if the number of currently operating boilers is greater than one, the load will be continuously adjusted and optimized according to the principle of secondary load distribution. When the main control boiler unit pointed to by the boiler unit pointer i can no longer reduce its load, in order to reduce the number of startups, the boiler unit pointed to will be reduced to the minimum load according to the target load, and the fire source will be retained and the fire source boiler will be the main control.

[0105] In this embodiment, the concept of a "fire starter" refers to a seed of fire that, given the appropriate conditions, burns rapidly. Conventional oil / gas boilers require approximately one hour to go from cold start to normal operation, which cannot meet the rapid production demands of users. Therefore, to respond to users' immediate production requirements, this invention establishes a "fire starter boiler" concept for multiple boilers: during normal operation, the fire starter is transmitted via a pointer, and the boiler designated as the fire starter remains continuously running; when the load is reduced, the fire starter boiler acts as the last boiler in the main control and regulation; when the load is increased, the fire starter boiler transmits the fire starter to the next boiler as the load increases; the fire starter boiler will only shut down when a fault interlock occurs or the system stops when the stop button is pressed.

[0106] For intelligent boiler control, each boiler automatically adjusts according to the allocated load transmitted by the server and feeds back the current load and equipment information to the server.

[0107] The concept of a "fire-starting boiler" significantly reduces the frequency of boiler start-ups and shutdowns, thereby reducing energy consumption.

[0108] The aforementioned multi-boiler intelligent agent collaborative control method encodes and sorts all boilers, then uses a single-pointer polling sequential control method for control. It combines the number of boilers participating in operation with the spare capacity of boilers requiring coordinated control for load regulation control. Furthermore, based on a secondary load allocation algorithm combined with the main control mode of the pilot boiler, it performs load regulation control on the regulated boilers, enabling boilers of different tonnages to participate in collaborative control simultaneously. This significantly reduces the number of frequent boiler start-ups and shutdowns, lowers energy consumption, makes boiler operation more precise, and effectively solves the difference between output load and actual demand.

Figure 6 As shown, corresponding to the above-described multi-boiler intelligent agent collaborative control method, the present invention also provides a multi-boiler intelligent agent collaborative control device 300. This multi-boiler intelligent agent collaborative control device 300 includes a unit for executing the above-described multi-boiler intelligent agent collaborative control method, and the device can be configured in a server. Specifically, please refer to... Figure 6The multi-boiler intelligent collaborative control device 300 includes an encoding and sorting unit 301, a single pointer control unit 302, a first judgment unit 303, a second judgment unit 304, an adjustment control unit 305, a combination selection unit 306, and a load adjustment unit 307.

[0110] The coding and sorting unit 301 is used to encode and sort all boilers in the boiler room to obtain a boiler coding table; the single pointer control unit 302 is used to sort and control the sorted boilers through a single pointer polling sequence control method; the first judgment unit 303 is used to determine whether the number of boilers participating in operation is equal to zero; the second judgment unit 304 is used to determine whether the boiler margin requiring coordinated control is not equal to zero if the number of boilers participating in operation is equal to zero; the adjustment control unit 305 is used to start the boiler pointed to by the pointer if the boiler margin requiring coordinated control is not equal to zero, and the individual boilers follow the target load adjustment amount to adjust and control the load by adding and subtracting loads; the combination selection unit 306 is used to select the optimal efficiency combination under the condition of meeting the current demand load if the number of boilers participating in operation is not equal to zero; the load adjustment unit 307 is used to perform load adjustment control on the regulated boilers based on the secondary load allocation algorithm combined with the main control method of the pilot boiler.

[0111] In one embodiment, the single pointer control unit 302 is used to point the pointer to the starting position of the boiler coding table. According to the control conditions, the pointer number increases, and the size of the element pointed to by the pointer and the target element are compared one by one. If the pointer is not less than the total number of boilers, then one cycle ends.

[0112] In one embodiment, such as Figure 7 As shown, the load adjustment unit 307 includes a quantity judgment subunit 3071, a load increase control subunit 3072, and a load decrease control subunit 3073.

[0113] The quantity judgment subunit 3071 is used to determine whether the number of boilers participating in operation is greater than zero; the load increase control subunit 3072 is used to perform load increase coordination control on the regulated boilers if the number of boilers participating in operation is greater than zero; the load decrease control subunit 3073 is used to perform load decrease coordination control on the regulated boilers if the number of boilers participating in operation is not greater than zero.

[0114] In one embodiment, such as Figure 8 As shown, the load increase control subunit 3072 includes a start-up module 30721, a first adjustment module 30722, and a secondary distribution module 30723.

[0115] The starting module 30721 is used to start the boiler pointed to by the operation pointer and perform full-load regulation operation; the first regulation module 30722 is used to increment the pointer by one when the current boiler is at full load, and sequentially start the boiler unit pointed to by the pointer to operate at full load, decrement the number of boilers participating in operation by one, and increase the value of the decrement of the number of boilers participating in operation each time until the number of boilers participating in operation is equal to zero. When the last boiler is started, the currently started boiler automatically follows the coordinated control margin to perform automatic load regulation control; the secondary distribution module 30723 is used to optimize and adjust the boilers participating in load regulation after the load increase distribution is completed, and perform secondary load redistribution according to the boiler operation curve.

[0116] In one embodiment, such as Figure 9 As shown, the load reduction control subunit 3073 includes a load reduction module 30731 and a main control module 30732.

[0117] The load reduction module 30731 is used to sequentially reduce the load and shut down boilers one by one according to the principle of first-to-start and first-to-stop. The main control module 30732 is used to optimize and adjust according to the principle of secondary redistribution when the number of operating boilers is greater than 1 after the load reduction allocation is completed. When the number of operating boilers is 1 after the load reduction allocation is completed, the boiler pointed to by the pointer is reduced according to the target load until it is reduced to the minimum load, and the fire source is retained. When the load reduction of the currently controlled boiler reaches the set value, the fire source boiler will take over the main control.

[0118] It should be noted that those skilled in the art can clearly understand that the specific implementation process of the above-mentioned multi-boiler intelligent agent collaborative control device 300 and each unit can be referred to the corresponding description in the foregoing method embodiments.

[0126] The processor 502 is used to run a computer program 5032 stored in the memory to perform the following steps:

[0127] All boilers in the boiler room are coded and sorted to obtain a boiler coding table; the sorted boilers are controlled in sequence using a single-pointer polling method; it is determined whether the number of boilers participating in operation is zero; if the number of boilers participating in operation is zero, it is determined whether the boiler margin requiring coordinated control is not zero; if the boiler margin requiring coordinated control is not zero, the boiler pointed to by the pointer is started, and the individual boilers follow the target load adjustment to adjust the load by adding and subtracting loads; if the number of boilers participating in operation is not zero, the optimal efficiency combination is selected under the condition of meeting the current demand load; the load adjustment control of the regulated boilers is performed based on a secondary load allocation algorithm combined with the main control method of the pilot boiler.

[0128] In one embodiment, when implementing the step of sorting and controlling the sorted boilers using a single-pointer polling sequence control method, the processor 502 specifically implements the following steps:

[0129] The pointer is moved to the beginning of the boiler coding table. According to the control conditions, the pointer count is increased, and the size of the element pointed to by the pointer and the target element are compared one by one. If the pointer is not less than the total number of boilers, then one cycle ends.

[0130] In one embodiment, when the processor 502 implements the load regulation control step of the boiler under control based on the algorithm of secondary load allocation combined with the main control mode of the pilot boiler, the specific steps are as follows:

[0131] Determine if the number of boilers participating in operation is greater than zero; if the number of boilers participating in operation is greater than zero, then implement load increase coordination control for the boilers being regulated.

[0132] In one embodiment, when implementing the step of load increase coordinated control of the regulated boiler, the processor 502 specifically implements the following steps:

[0133] The system starts the boiler indicated by the pointer and operates it at full load. Once the current boiler reaches full load, the pointer increments by one, and the boiler units indicated by the pointer are started sequentially at full load. The number of boilers participating in the operation is decremented by one, and the decrement value is increased each time until the number of boilers participating in the operation equals zero. After the last boiler starts, the currently started boiler automatically follows the coordinated control margin for automatic load adjustment control. After the load increase distribution is completed, the boilers participating in the load regulation are optimized and adjusted, and the load is redistributed a second time based on the boiler operation curve.

[0134] In one embodiment, after performing the step of determining whether the number of boilers participating in operation is greater than zero, the processor 502 further performs the following steps:

[0135] If the number of boilers involved in operation is not greater than zero, then load reduction and coordinated control will be implemented for the boilers under control.

[0136] In one embodiment, when implementing the step of load reduction and coordinated control of the regulated boiler, the processor 502 specifically implements the following steps:

[0137] Following the principle of first-to-start and first-to-stop, the pointer increments, and the boilers are shut down one by one in sequence as the load is reduced. When the load reduction allocation is completed and the number of operating boilers is greater than one, the boilers are optimized and adjusted according to the principle of secondary redistribution. When the load reduction allocation is completed and the number of operating boilers is one, the boiler pointed to by the pointer is reduced according to the target load until it is reduced to the minimum load. The fire source is retained. When the load reduction of the currently controlled boiler reaches the set value, the fire source boiler takes over the main control.

[0138] The set value is half of the load of the master controller.
