[0042] The embodiments of the present invention provide a boiler damper adjustment method and device.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0044] like Figure 1 The flowchart of a boiler damper adjustment method according to an embodiment of the present invention is shown. The execution subject of the boiler damper adjustment method provided by the embodiment of the present invention includes but is not limited to a computer. The method shown in the figure includes:

[0045] Step S1, obtaining a correlation relationship between damper parameters of the boiler, and determining a damper angle deviation range based on the correlation relationship between the damper parameters;

[0046] Step S2, according to the preset damper opening instruction, collecting damper angle data corresponding to the damper opening instruction, and determining the actual damper opening according to the correlation between the damper angle data and the damper parameters;

[0047] Step S3: updating the damper opening instruction according to the actual damper opening, the damper opening instruction and the damper angle deviation range to complete the boiler damper adjustment.

[0048] As an embodiment of the present invention, the damper parameter correlation includes the relationship between the secondary air nozzle wind speed, the damper resistance coefficient and the damper angle.

[0049] The mathematical relationship between the secondary air outlet velocity, damper resistance coefficient, and damper (damper) angle can be further determined through model testing or fluid flow calculations based on actual furnace verification tests. This can be considered as replacing damper adjustment characteristic tests conducted on actual furnaces with model testing or fluid flow calculations. This approach has the advantage of avoiding a series of negative impacts associated with starting air supply equipment.

[0050] Furthermore, the boiler's regulatory performance requirements dictate that, under a given opening command, the fluid velocity deviation within the damper's duct must be controlled within a specific range. Specifically, this velocity deviation range can be converted into an allowable range of damper angle deviation using the boiler's damper parameter correlation. This velocity deviation range is a process requirement, such as a 5% allowable velocity deviation range.

[0051] Specifically, the preset damper opening instructions may be 3-5 damper opening instructions set within the opening range of 0-100% (equally spaced). 3-5 damper opening instructions are set between 0-100% (equally spaced), such as 0%, 30%, 60%, 90%, and 100% as sampling points, and damper angle data corresponding to the damper opening instructions are collected.

[0052] In this embodiment, if Figure 2 As shown, according to the relationship between the damper angle data and the damper parameters, the actual damper opening is determined as follows:

[0053] Step S21, determining the secondary air nozzle velocity based on the damper angle data and the damper parameter correlation;

[0054] Step S22: determining the actual opening of the damper according to the wind speed of the secondary air nozzle.

[0055] The damper angle corresponding to each opening instruction is measured. The actual opening can be defined as the measured angle divided by 90°, or the wind speed corresponding to the measured angle divided by the maximum wind speed corresponding to 90°. The correspondence between the actual opening corresponding to the damper angle and the opening instruction is checked. The secondary air nozzle velocity corresponding to the damper angle is calculated using the correlation between the boiler's damper parameters. Thus, the measurement of the secondary air velocity (secondary air nozzle velocity) is replaced by the angle measurement in the actual furnace, avoiding a series of negative effects brought about by the startup of the air supply equipment.

[0056] As an embodiment of the present invention, Figure 3 As shown, updating the damper opening command according to the actual damper opening, the damper opening command and the damper angle deviation range includes:

[0057] Step S31, determining a deviation value corresponding to the damper opening instruction based on the actual damper opening and the damper opening instruction;

[0058] Step S32: If the deviation value exceeds the damper angle deviation range, the damper opening instruction is updated according to the deviation value.

[0059] Among them, the deviation value corresponding to the damper opening instruction is determined. If the actual opening corresponds to the opening instruction one-to-one, it means that the damper instruction is normal. If the deviation is much beyond the allowable range, that is, the damper angle deviation range, the damper opening instruction is updated.

[0060] Furthermore, the damper opening instruction is updated according to the deviation value by eliminating defects so that the damper angle corresponding to the opening instruction is within the allowable deviation range, thereby making the deviation between the actual damper opening and the opening instruction within the allowable range.

[0061] In a specific embodiment of the present invention, in order to pass the positioning inspection as soon as possible without starting the air supply equipment and ensure that the adjustment performance of the air door (baffle) meets the requirements of boiler combustion, the following method is used: Figure 4 The boiler damper adjustment method is shown.

[0062] In this embodiment, if Figure 5 As shown, a butterfly valve is commonly used in coal-fired boilers to control the flow rate of fluid within the pipeline. To determine whether the actual position (opening feedback) of the butterfly valve is consistent with the desired position (opening command), the valve needs to be positioned. The boiler's damper (damper) is a type of butterfly valve. The damper (damper) angle refers to the angle between the damper (damper) and the airflow direction. When the angle is 0, the damper (damper) is 100% open; when the angle is 90°, the damper (damper) is 0% open.

[0063] In this embodiment, if Figure 4 The method shown specifically includes the following steps:

[0064] (1) Obtain the mathematical relationship between the secondary air nozzle velocity, damper resistance coefficient, and damper (damper) angle. This relationship can be further obtained through model testing or fluid calculations based on the actual furnace verification test. It can be considered that the damper adjustment characteristic test conducted on the actual furnace is replaced by the model test or fluid calculation. The advantage of this is that it avoids a series of negative effects caused by starting the air supply equipment.

[0065] (2) Determine the allowable range of damper (damper) angle deviation. The boiler's regulatory performance requirements determine that, under a certain opening instruction, the fluid velocity deviation in the pipe where the damper (damper) is located should be controlled within a certain range. This velocity deviation range can be converted into the allowable range of damper (damper) angle deviation using the mathematical relationship obtained in step (1). This velocity deviation range is a process requirement, such as a 5% velocity deviation allowable range.

[0066] (3) Set 3-5 damper opening instructions at equal intervals within the opening range of 0-100%. Taking into account the workload of actual furnace measurement, a sampling inspection method is adopted to set 3-5 damper opening instructions between 0-100% (equally spaced), such as 0%, 30%, 60%, 90%, and 100% as sampling points. If there are more than 5 damper opening instructions, the number of samples is too large and the workload is too large; if there are less than 3, the number of samples is too small and the representativeness is insufficient. The specific number of sampling points can be adjusted according to the actual situation on site. The specific number of sampling points is given manually and it is sufficient to meet the above requirements.

[0067] (4) Measure the damper (damper) angle corresponding to each opening instruction. The actual opening can be defined as the measured angle divided by 90°, or the actual opening can be defined as the wind speed corresponding to the measured angle divided by the maximum wind speed corresponding to 90°. Check the correspondence between the actual opening corresponding to the damper (damper) angle and the opening instruction. Use the mathematical relationship obtained in step (1) to calculate the secondary air speed corresponding to the damper (damper) angle. In this way, the angle measurement in the actual furnace replaces the secondary air speed measurement, avoiding a series of negative effects brought about by starting the air supply equipment, and at the same time improving the accuracy of the measurement results in the actual furnace. If necessary, the actual secondary air speed can be measured to verify the accuracy of the mathematical relationship corresponding to step (1).

[0068] If the actual opening corresponds to the opening command one-to-one, it means that the damper command is normal. If the deviation is large and exceeds the allowable range, proceed to step (5).

[0069] (5) By eliminating defects, the damper (baffle) angle corresponding to the opening instruction is within the allowable deviation range, so that the deviation between the actual damper opening and the opening instruction is within the allowable range.

[0070] In summary, the above steps can be used to determine the accuracy of the opening instruction by measuring the angle and angle deviation, as well as whether the damper (damper) adjustment performance (wind speed) meets the requirements, thereby achieving the effect of eliminating defects while checking and preventing the boiler from igniting and running with defects.

[0071] In a specific embodiment of the present invention, the present invention converts the measurement of the secondary air flow velocity into the measurement of the damper (baffle) angle, and converts the allowable range of the flow velocity deviation into the allowable range of the damper (baffle) angle deviation, thereby making it possible to check the correspondence between the opening instruction and the actual opening to facilitate equipment troubleshooting while obtaining the wind speed information corresponding to the opening instruction.

[0072] In this embodiment, the functional relationship between the damper (baffle) resistance coefficient ζ and the angle x is obtained by fluid calculation. A typical functional relationship is, for example, formula (1):

[0073]

[0074] According to formula (2), the relationship between the secondary air nozzle velocity v and the damper (baffle) angle x is finally calculated, as follows: Figure 6 shown.

[0075]

[0076] In formula (2), Δp refers to the difference between the total pressure of the secondary air box and the pressure of the furnace, which can be obtained by measurement, and ρ is the density of the secondary air, which can be obtained by measuring the secondary air temperature and the thermal properties of the air.

[0077] Furthermore, given the required wind speed and the upper and lower deviations of the wind speed, the maximum angle deviation allowed when the damper (baffle) is at different angles is calculated using formulas (1)-(2) under the condition that the wind speed deviation does not exceed ±5%. Figure 7 As shown, it can be seen that in the static inspection within the range of 0 to 80°, as long as the angle deviation of the damper (baffle) does not exceed 1°, the secondary air nozzle speed deviation can be controlled within ±5%, thereby meeting the actual needs of boiler combustion.

[0078] In summary, the above process can be used to check the consistency between the actual opening corresponding to the damper angle and the opening instruction, and the above process can be used to obtain the secondary air speed information at a given damper angle or damper opening instruction.

[0079] The present invention obtains the allowable range of the damper angle deviation through the correlation between the boiler's damper parameters, thereby making it possible to check the correspondence between the opening instruction and the actual opening to facilitate equipment troubleshooting, while obtaining the wind speed information corresponding to the opening instruction, avoiding the problems of high energy consumption, being detrimental to human health, and low accuracy of test results, achieving the effect of troubleshooting while checking, and preventing the equipment from operating with defects.

[0084] As an embodiment of the present invention, the damper parameter correlation includes the relationship between the secondary air nozzle wind speed, the damper resistance coefficient and the damper angle.

[0085] In this embodiment, if Figure 9 As shown, the actual opening module 20 includes:

[0086] The nozzle wind speed unit 21 is used to determine the secondary air nozzle wind speed according to the damper angle data and the correlation between the damper parameters;

[0087] The actual opening unit 22 is used to determine the actual opening of the damper according to the wind speed of the secondary air nozzle.
