Description

Technical Field

[0001] This invention relates to the field of heating equipment technology, and specifically to a control method for a segmented burner. Background Technology

[0002] Segmented combustion technology is now basically standard on gas water heaters, designed to address the issue of significant differences in inlet water temperature between winter and summer, thus improving user comfort. Segmented combustion technology divides the burner into multiple burners, igniting them progressively to adapt to varying inlet water temperatures and user needs.

[0003] In existing segmented burners, ignition typically begins with the edge burners, gradually increasing the number of burners towards the opposite side, until all burners are ignited. This control method ensures that the flame does not directly contact the cold water pipes during water heater startup, avoiding user discomfort from sudden temperature changes. Simultaneously, gradually increasing the number of burners allows for progressively higher combustion power to accommodate changes in inlet water temperature, thus guaranteeing stable outlet water temperature and user comfort.

[0004] However, the existing control method for segmented burners has the problem that the edge burners that are ignited at the beginning are used the most frequently, which inevitably leads to the shortest service life of the edge burners that are ignited at the beginning. Understandably, the service life of the edge burners that are ignited at the beginning directly determines the service life of the entire segmented burner. Summary of the Invention

[0005] To address the above technical problems, this invention proposes a control method, system, device, and medium for segmented burners, aiming to extend the service life of the edge burners in segmented burners.

[0006] This invention adopts the following technical solution: a control method for a segmented burner, comprising the following steps:

[0007] Step 102: Calculate the heat load required for the segmented burner;

[0008] Step 104: Determine the number of solenoid valves to be opened based on the required heat load;

[0009] Step 106: Obtain the current usage status and cumulative working time of each solenoid valve in the segmented burner;

[0010] Step 108: Based on the number of solenoid valves to be opened, the adjacency relationship between the solenoid valves in the segmented burner, the current usage status and cumulative working time of each solenoid valve, determine the control scheme for the solenoid valves.

[0011] Heat load refers to the amount of heat or thermal energy required by a system or device, and is typically used to describe the capacity and requirements of a heating, cooling, or heat supply system. The unit of measurement for heat load is usually a heat unit, such as kilowatt (kW) or British thermal units (BTU). The heat load required by a sectional burner can vary depending on factors such as water flow rate and temperature in the gas water heater piping. In a sectional burner, each section includes one or more solenoid valves and multiple burners. Each solenoid valve corresponds to several burners. The solenoid valves control the gas supply to each section of the sectional burner. The gas is burned through the burners, and the resulting flames transfer heat to the water for heating.

[0012] By calculating the heat load required by the segmented burner in real time, the number of solenoid valves to be opened is determined based on the required heat load. This allows for a more accurate match between the heat output of the segmented burner and actual needs, effectively improving the combustion efficiency of the segmented burner. Furthermore, by comprehensively considering the adjacency relationship between the solenoid valves in the segmented burner, their current operating status, and cumulative working time, a control scheme for the solenoid valves is determined. This allows for better allocation of the opening and closing of the solenoid valves, averaging the cumulative operating time of all burners in the segmented burner as evenly as possible. This avoids premature damage to the edge burners or even the entire segmented burner due to prolonged continuous operation of the edge solenoid valves, thereby extending the service life of the edge burners in the segmented burner and improving the overall stability and reliability of the segmented burner.

[0013] Preferably, in step 102, calculating the heat load required by the segmented burner includes:

[0014] Obtain the inlet water temperature, outlet water temperature, and water flow rate of the water heater;

[0015] The required heat load for the segmented burner is calculated based on the inlet water temperature, outlet water temperature, and water flow rate of the water heater.

[0016] Preferably, the formula for calculating the heat load required by the segmented burner is:

[0017] W = F × (T2 - T1) × C

[0018] Where W represents the heat load required by the segmented burner, F represents the water flow rate of the water heater, T1 represents the inlet water temperature, T2 represents the outlet water temperature, and C represents the specific heat capacity of water.

[0019] Preferably, in step 104, determining the number of solenoid valves to be opened based on the required heat load includes:

[0020] Obtain the theoretical heat load range for each section of the segmented burner;

[0021] The actual heat load range of each segment is divided according to the theoretical heat load range of each segment;

[0022] Match the required heat load with the actual heat load range of each segment to determine the segment where the required heat load is located, and obtain the number of solenoid valves corresponding to that segment, which is the number of solenoid valves that need to be opened.

[0023] Preferably, in step 108, based on the number of solenoid valves to be opened, the adjacency relationship between the solenoid valves in the segmented burner, and the current usage status and cumulative working time of each solenoid valve, a control scheme for the solenoid valves is determined, including:

[0024] Based on the current operating status of each solenoid valve in the segmented burner, determine the number of solenoid valves that have been opened.

[0025] Compare the number of solenoid valves that are already open with the number of solenoid valves that need to be opened.

[0026] If the number of already activated solenoid valves is less than the required number, then the control scheme for the solenoid valves is determined based on the adjacency relationship between the solenoid valves in the segmented burner and the cumulative operating time of each solenoid valve.

[0027] If the number of solenoid valves already opened equals the number of solenoid valves that need to be opened, then maintain the current operating status of each solenoid valve in the segmented burner.

[0028] If the number of solenoid valves already opened is greater than the number of solenoid valves that need to be opened, then the control scheme for the solenoid valves is determined based on the cumulative working time of each solenoid valve in the segmented burner.

[0029] Preferably, if the number of already activated solenoid valves is less than the number of solenoid valves required to be activated, then based on the adjacency relationship between the solenoid valves in the segmented burner and the cumulative operating time of each solenoid valve, a control scheme for the solenoid valves is determined, including:

[0030] Get the cumulative operating time of the two solenoid valves adjacent to the already opened solenoid valve.

[0031] Prioritize opening solenoid valves with shorter cumulative operating time;

[0032] Repeat the above steps until the required number of solenoid valves are opened is reached.

[0033] Preferably, if the number of already activated solenoid valves exceeds the required number of activated solenoid valves, a control scheme for the solenoid valves is determined based on the cumulative operating time of each solenoid valve in the segmented burner, including:

[0034] Get the cumulative operating time of the opened solenoid valves;

[0035] Prioritize closing the solenoid valves that have been open for a longer period of time, until the required number of solenoid valves are reached.

[0036] A control system for a segmented burner includes:

[0037] The control target analysis module is used to calculate the heat load required by the segmented burner and determine the number of solenoid valves to be opened based on the calculated heat load.

[0038] The data acquisition module is used to acquire the current usage status and cumulative working time of each solenoid valve in the segmented burner;

[0039] The control scheme generation module is used to determine the control scheme for the solenoid valves based on the number of solenoid valves to be opened, the adjacency relationship between the solenoid valves in the segmented burner, the current usage status and cumulative working time of each solenoid valve.

[0040] A computer device, comprising:

[0041] processor;

[0042] Memory for storing the executable instructions of the processor;

[0043] The processor is configured to execute a segmented burner control method as described above by executing the executable instructions.

[0044] A computer-readable storage medium,

[0045] The computer-readable storage medium stores a computer program that, when executed by a processor, implements a control method for a segmented burner as described above.

[0046] The beneficial technical effects of this invention include at least the following: It employs a control method, system, device, and medium for a segmented burner. By calculating the heat load required by the segmented burner in real time, the number of solenoid valves to be opened is determined based on the required heat load. This allows for a more accurate match between the heat output of the segmented burner and actual needs, effectively improving the combustion efficiency of the segmented burner. Furthermore, by comprehensively considering the adjacency relationship between the solenoid valves in the segmented burner, the current usage status of each solenoid valve, and the cumulative working time, a control scheme for the solenoid valves is determined. This allows for better allocation of the opening and closing of the solenoid valves, averaging the cumulative usage time of all burners in the segmented burner as evenly as possible. This avoids premature damage to the edge burners or even failure of the entire segmented burner due to prolonged continuous operation of the edge solenoid valves, thereby extending the service life of the edge burners in the segmented burner and improving the stability and reliability of the entire segmented burner.

[0047] Other features and advantages of the present invention will be disclosed in detail in the following detailed description and accompanying drawings. Attached Figure Description

[0048] The invention will be further described below with reference to the accompanying drawings:

[0052] Figure 4 This is a schematic diagram of the structure of a computer device according to an embodiment of the present invention.

[0053] The components include: 1. Solenoid valve, 2. Gas distribution pipe, 3. Flame burner, 4. Ignition needle, 5. Feedback needle, 6. Control target analysis module, 7. Data acquisition module, 8. Control scheme generation module, 9. Processor, and 10. Memory. Detailed Implementation

[0054] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0055] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” are used only to indicate orientation or positional relationship for the convenience of describing the embodiments and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0056] Please see the appendix Figure 1Taking a three-stage burner from the existing technology as an example, the illustrated three-stage burner includes three solenoid valves, three gas distribution pipes, and six burner bars. Each solenoid valve corresponds to two burner bars through a gas distribution pipe. The ignition needle and feedback needle are fixedly installed on the right burner bars A and B. The control method of the three-stage burner is as follows: each ignition first opens the right solenoid valve to supply gas to the right burner bars A and B. The gas burns through the burner bars, and the resulting flame transfers heat to the water for heating. Burner A and burner B constitute one section. If the maximum heat load of this section is still insufficient to heat the water to the preset outlet temperature, the middle solenoid valve is opened to supply gas to the middle burners C and D, increasing the number of burners involved in combustion to four. Burners A, B, C, and D constitute two sections. If the maximum heat load of this section is still insufficient to heat the water to the preset outlet temperature, the left solenoid valve is opened to supply gas to the left burners E and F, increasing the number of burners involved in combustion to six, thus achieving the maximum heat load of the three-section burner. It can be seen that in the existing three-section burner control method, the two burners on the right are used most frequently, followed by the two in the middle, and the two on the left are used least frequently. This results in the shortest service life of the two burners on the right. Understandably, the service life of the two burners on the right directly determines the service life of the entire three-section burner.

[0057] Therefore, this embodiment provides a control method for a segmented burner, please refer to the appendix. Figure 2 This includes the following steps:

[0058] Step 102: Calculate the heat load required for the segmented burner.

[0059] Heat load refers to the amount of heat or thermal energy required by a system or device, and is typically used to describe the capacity and requirements of a heating, cooling, or heat supply system. The unit of measurement for heat load is usually a heat unit, such as kilowatt (kW) or British thermal unit (BTU). The heat load required by a segmented burner can vary depending on factors such as water flow rate and water temperature in the gas water heater piping.

[0060] Step 104: Determine the number of solenoid valves to be opened based on the required heat load.

[0061] Step 106: Obtain the current usage status and cumulative working time of each solenoid valve in the segmented burner.

[0062] The method for obtaining the current operating status and cumulative working time of each solenoid valve in the segmented burner can be as follows: Sensors or monitoring devices are used to monitor the on / off status of each solenoid valve. The sensors or monitoring devices determine whether the solenoid valve is open or closed by detecting changes in its operating voltage or current. Then, a timer starts counting when the solenoid valve is open and pauses when it is closed to obtain the cumulative working time of each solenoid valve.

[0063] Step 108: Based on the number of solenoid valves to be opened, the adjacency relationship between the solenoid valves in the segmented burner, the current usage status and cumulative working time of each solenoid valve, determine the control scheme for the solenoid valves.

[0064] By calculating the heat load required by the segmented burner in real time, the number of solenoid valves to be opened is determined based on the required heat load. This allows for a more accurate match between the heat output of the segmented burner and actual needs, effectively improving the combustion efficiency of the segmented burner. Furthermore, by comprehensively considering the adjacency relationship between the solenoid valves in the segmented burner, their current operating status, and cumulative working time, a control scheme for the solenoid valves is determined. This allows for better allocation of the opening and closing of the solenoid valves, averaging the cumulative operating time of all burners in the segmented burner as evenly as possible. This avoids premature damage to the edge burners or even the entire segmented burner due to prolonged continuous operation of the edge solenoid valves, thereby extending the service life of the edge burners in the segmented burner and improving the overall stability and reliability of the segmented burner.

[0065] On the other hand, in this embodiment, step 102, calculating the heat load required by the segmented burner, includes:

[0066] Obtain the inlet water temperature, outlet water temperature, and water flow rate of the water heater;

[0067] The required heat load for the segmented burner is calculated based on the inlet water temperature, outlet water temperature, and water flow rate of the water heater.

[0068] The inlet and outlet temperatures of the water heater can be obtained using temperature detection devices installed near the inlet and outlet, such as thermistors (RTDs), thermistor-type temperature sensors, thermocouples, and infrared temperature sensors. The water flow rate can be obtained using flow detection devices installed on the inlet or outlet pipes of the water heater, such as flow meters and pulse counters.

[0069] By acquiring the inlet and outlet water temperatures and water flow rate of the water heater, the heat load required by the segmented burner can be calculated in real time. This allows for a more accurate match between the burner's heat output and actual demand, providing a precise basis for determining the number of solenoid valves that need to be opened. This effectively improves combustion efficiency and reduces energy waste.

[0070] On the other hand, in this embodiment, the calculation expression for the heat load required by the segmented burner is:

[0071] W = F × (T2 - T1) × C

[0072] Where W represents the heat load required by the segmented burner, F represents the water flow rate of the water heater, T1 represents the inlet water temperature, T2 represents the outlet water temperature, and C represents the specific heat capacity of water.

[0073] The specific heat capacity of water is 4.18 J / g·℃, meaning that every gram of water needs to absorb 4.18 joules of heat when the temperature rises by 1 degree Celsius.

[0074] On the other hand, in this embodiment, step 104, determining the number of solenoid valves to be opened based on the required heat load, includes:

[0075] Obtain the theoretical heat load range for each section of the segmented burner;

[0076] The actual heat load range of each segment is divided according to the theoretical heat load range of each segment;

[0077] Match the required heat load with the actual heat load range of each segment to determine the segment where the required heat load is located, and obtain the number of solenoid valves corresponding to that segment, which is the number of solenoid valves that need to be opened.

[0078] The design of the segmented burner clearly defines the maximum and minimum heat load of a single burner and the heat load power range of each segment, i.e., the theoretical heat load range of each segment in the segmented burner.

[0079] For example, taking a three-section burner with six burners as an example, assuming the current required heat load of the three-section burner is 9kW, the maximum heat load of a single burner in the three-section burner is 5kW and the minimum heat load is 2kW, the theoretical heat load range of each section is:

[0080] The heat load range for a single section with two burners is 4kW-10kW.

[0081] The heat load range for the two-section, four-burner configuration is 8kW-20kW.

[0082] The heat load range of the three-section, six-burner system is 12kW-30kW.

[0083] In the design of segmented burners, to prevent low-pressure interruptions—that is, situations where insufficient gas supply pressure during burner operation leads to inability to burn normally or unstable combustion—overlapping heat load zones are incorporated between the segments. Since the maximum heat load has the greatest impact on the burner's lifespan, the actual control of the segmented burner should avoid operating at maximum burner load as much as possible. Therefore, the actual heat load ranges for each segment are divided according to their theoretical heat load ranges as follows:

[0084] The heat load range for the two burners in section 1 is 4kW-8kW.

[0085] The heat load range for the two-section, four-burner configuration is 8kW-12kW.

[0086] The heat load range of the three sections with six burners is 12kW-30kW.

[0087] Therefore, the current required heat load of 9kW falls into the two-segment heat load range, that is, the heat load range corresponding to opening 2 solenoid valves and 4 burners.

[0088] By dividing the actual heat load range of each segment according to the theoretical heat load range of each segment, and then matching the required heat load with the actual heat load range of each segment, the number of solenoid valves to be opened can be determined. This can avoid overload or insufficient heat load in some segments, so that the burner can be balanced between each segment, which can extend the service life of the burner in the combustion water heater to a certain extent, and at the same time, more accurately determine the number of solenoid valves to be opened.

[0089] On the other hand, in this embodiment, in step 108, based on the number of solenoid valves to be opened, the adjacency relationship between the solenoid valves in the segmented burner, the current usage status and cumulative working time of each solenoid valve, the control scheme for the solenoid valves is determined, including:

[0090] Based on the current operating status of each solenoid valve in the segmented burner, determine the number of solenoid valves that have been opened.

[0091] Compare the number of solenoid valves that are already open with the number of solenoid valves that need to be opened.

[0092] If the number of already activated solenoid valves is less than the required number, then the control scheme for the solenoid valves is determined based on the adjacency relationship between the solenoid valves in the segmented burner and the cumulative operating time of each solenoid valve.

[0093] If the number of solenoid valves already opened equals the number of solenoid valves that need to be opened, then maintain the current operating status of each solenoid valve in the segmented burner.

[0094] If the number of solenoid valves already opened is greater than the number of solenoid valves that need to be opened, then the control scheme for the solenoid valves is determined based on the cumulative working time of each solenoid valve in the segmented burner.

[0095] On the other hand, in this embodiment, if the number of already activated solenoid valves is less than the number of solenoid valves required to be activated, a control scheme for the solenoid valves is determined based on the adjacency relationship between the solenoid valves in the segmented burner and the cumulative operating time of each solenoid valve, including:

[0096] Get the cumulative operating time of the two solenoid valves adjacent to the already opened solenoid valve.

[0097] Prioritize opening solenoid valves with shorter cumulative operating time;

[0098] Repeat the above steps until the required number of solenoid valves are opened is reached.

[0099] In this embodiment, when the number of already opened solenoid valves is less than the required number of solenoid valves to be opened, i.e., when more solenoid valves need to be added, considering that if the solenoid valve with the shortest cumulative working time is not adjacent to the currently open solenoid valve, i.e., the burners controlled by the two are not adjacent, the flame cannot be transmitted, which means that the newly opened burner cannot be ignited, the two solenoid valves adjacent to the already opened solenoid valves are opened first. Then, from the two solenoid valves adjacent to the already opened solenoid valves, the solenoid valve with the shorter cumulative working time is opened first. If the required number of solenoid valves to be opened is still not reached, the solenoid valve with the shorter cumulative working time is opened first from the two solenoid valves adjacent to the newly opened solenoid valves, until the required number of solenoid valves to be opened is reached.

[0100] By prioritizing the opening of the two solenoid valves adjacent to the already opened solenoid valve, the operation of the sectional burner can be made more stable. This is because it allows for smooth flame transmission between adjacent solenoid valves, avoiding disconnection or interruption and ensuring continuous heating of the sectional burner. At the same time, by selecting solenoid valves with shorter cumulative working time as the indicator for increasing the number of solenoid valves, the heat load of each section in the sectional burner can be balanced. This avoids the situation where the edge burner of one section works continuously for a long time while the other burners provide a lighter heat load. By averaging the cumulative usage time of all burners in the sectional burner as much as possible, the service life of the entire sectional burner can be extended, which has high practical value.

[0101] On the other hand, in this embodiment, if the number of already activated solenoid valves is greater than the number of solenoid valves that need to be activated, a control scheme for the solenoid valves is determined based on the cumulative operating time of each solenoid valve in the segmented burner, including:

[0102] Get the cumulative operating time of the opened solenoid valves;

[0103] Prioritize closing the solenoid valves that have been open for a longer period of time, until the required number of solenoid valves are reached.

[0104] In this embodiment, when the number of already opened solenoid valves is greater than the number of solenoid valves that need to be opened, i.e., when it is necessary to reduce the number of solenoid valves, the solenoid valves with longer cumulative working time are closed first. If the number of solenoid valves that need to be opened has not yet been reached, the solenoid valves with longer cumulative working time are closed first from the already opened solenoid valves after they have been closed, until the number of solenoid valves that need to be opened is reached.

[0105] By selecting solenoid valves with longer cumulative operating time as a criterion for reducing the number of solenoid valves, the heat load of each section in the segmented burner can be balanced. This avoids the situation where the edge burners of one section work continuously for a long time while the other burners provide a lighter heat load. It also averages out the cumulative usage time of all burners in the segmented burner as much as possible, thereby extending the service life of the entire segmented burner, which has high practical value.

The control method for a segmented burner as described in claim 1, characterized in that, If the number of already activated solenoid valves exceeds the required number, the control scheme for the solenoid valves is determined based on the cumulative operating time of each solenoid valve in the segmented burner, including: Get the cumulative operating time of the opened solenoid valves; Prioritize closing the solenoid valves that have been open for a longer period of time, until the required number of solenoid valves are reached.

6. A control system for a segmented burner, characterized in that, include: The control target analysis module is used to calculate the heat load required by the segmented burner and determine the number of solenoid valves to be opened based on the calculated heat load. The data acquisition module is used to acquire the current usage status and cumulative working time of each solenoid valve in the segmented burner; The control scheme generation module is used to determine the number of solenoid valves that are currently open based on the current operating status of each solenoid valve in the segmented burner, and compare the number of open solenoid valves with the number of solenoid valves that need to be opened. If the number of already activated solenoid valves is less than the required number, then the control scheme for the solenoid valves is determined based on the adjacency relationship between the solenoid valves in the segmented burner and the cumulative operating time of each solenoid valve. If the number of solenoid valves already opened equals the number of solenoid valves that need to be opened, then maintain the current operating status of each solenoid valve in the segmented burner. If the number of solenoid valves already opened is greater than the number of solenoid valves that need to be opened, then the control scheme for the solenoid valves is determined based on the cumulative working time of each solenoid valve in the segmented burner. The control scheme generation module performs the following steps when the number of activated solenoid valves is less than the required number of activated solenoid valves: Get the cumulative operating time of the two solenoid valves adjacent to the already opened solenoid valve. Prioritize opening solenoid valves with shorter cumulative operating time; Repeat the above steps until the required number of solenoid valves are opened is reached.
