FIG. 1 is a flow diagram of a method for controlling wind-dust parameters of a micro-oil ignition burner provided by embodiments of the present invention.
As shown in FIG. 1, an embodiment of the present invention provides a micro-oil ignition burner wind-dust parameter control method, the executing body may be a boiler control system, and the method mainly includes the following steps: 101, collecting high temperature point temperature information and fault point temperature information of the pulverised coal burner during combustion.
In a specific realisation process, thermocouples or other temperature sensors are installed at the high temperature point location and the vulnerable location of the burner, so that the high temperature point temperature information corresponding to the high temperature point location and the fault point temperature information corresponding to the vulnerable location can be conveniently collected. The temperature can be collected in real time or at intervals. 0506953 102, determining the current ignition stage of the pulverised coal burner, the current ignition stage including the fuel atomisation stage, the primary chamber combustion stage and the secondary chamber combustion stage.
Micro-oil ignition is to use a smaller power to ignite a part of the powder-containing gas stream of higher concentration, and use the flame propagation ability of the powder-containing gas stream itself to gradually ignite the whole powder-containing gas stream, so as to achieve a greater saving of the oil used for ignition. Therefore, in the whole ignition process, there will be a number of different phases, different phases of the corresponding wind powder parameter requirements are also different, in order to better achieve the adjustment of wind powder parameters, it is necessary to accurately determine the current ignition stage.
Specifically, the ignition duration can be determined, the ignition duration referring to a time period from the start of ignition to the present. Then detecting the pulverised coal flame size, the pulverised coal flame temperature and the pulverised coal flame energy; when the ignition duration is less than the first preset duration, and the pulverised coal flame size is less than the first preset size, and the pulverised coal flame temperature is less than the first preset temperature, and the pulverised coal flame energy is less than the first preset energy, determining that the current ignition stage is the fuel atomisation stage; when the ignition duration is in the range between the first preset duration and the second preset duration, and the pulverised coal
When the ignition time length is between the first preset time length and the second preset time length, and the pulverised coal flame temperature is between the first preset temperature and the second preset temperature, and the pulverised coal flame energy is between the first preset energy and the second preset energy, it is determined that the current ignition stage is the primary chamber combustion stage; when the ignition time length is between the second preset time length and the third preset time length, and the pulverised coal flame size is between the second preset size and the third preset size, and the pulverised coal flame size is between the second preset size and the When the ignition duration is between the second preset duration and the third preset duration, and the size of the pulverised coal flame is between the second preset size and the third preset size, and the temperature of the pulverised coal flame is between the second preset temperature and the third preset temperature, and the energy of the pulverised coal flame is between the second preset energy and the third preset energy, then it is determined that the 504953 current ignition stage is the secondary chamber combustion stage. Thus, the current ignition stage 1s accurately determined by different ignition durations, different flame sizes, different flame temperatures and different flame energies. 5 wherein, before determining the ignition duration, further comprising: under standard operating conditions, separately counting the ignition duration samples, pulverised coal flame size samples, pulverised coal flame temperature samples, and pulverised coal flame energy samples corresponding to the different ignition stage samples when the micro-oil is ignited; based on the ignition stage samples, the ignition duration samples, the pulverised coal flame size samples, the pulverised coal flame temperature samples, and the pulverised coal flame energy samples, constructing an ignition stage determination model, determining, by the ignition stage determination model, a first predetermined duration, a second predetermined duration, and a third predetermined duration, and a first predetermined size, a second predetermined size, and a third predetermined size, and a first predetermined temperature, a second predetermined temperature, and a third predetermined temperature, and a first predetermined energy, a second predetermined energy, and a third predetermined energy corresponding to different ignition stages.
By means of combining the big data neural network, the preset values of the ignition duration, the pulverised coal flame size, the pulverised coal flame temperature, and the pulverised coal flame energy corresponding to the fuel atomisation stage, the primary chamber combustion stage, and the secondary chamber combustion stage, respectively, are accurately determined. Moreover, the accuracy of determining the preset values for each stage can also be ensured by comparing the multiple parameters under standard operating conditions. 103, based on the correlation relationship between the ignition stage and the wind-dust parameters, the wind-dust parameters of the fuel atomisation stage, the primary chamber combustion stage and the secondary chamber combustion stage are determined respectively.

Based on high-temperature point temperature information, fault point temperature information and micro-oil ignition power, adjust the wind-powder flow rate, wind-powder temperature and pulverised coal ratio in the wind-powder parameters.
After determining the wind-powder parameters, a difference between the high-temperature point temperature information, the fault point temperature information, and the safety temperature threshold is first determined; and then the wind-powder flow rate, the wind-powder temperature, and the powder-coal ratio in the wind-powder parameters are adjusted based on the difference and the micro-oil ignition power.
Specifically, the difference between the high temperature point temperature information and the safe temperature threshold, and the difference between the fault point temperature information and the safe temperature threshold, in the whole process need to make sure that the difference is in the safe range, to make sure that the problem of excessive temperature does not occur. Then through the difference value combined with the micro-oil ignition power, and then go to the wind powder flow rate, wind powder temperature and the proportion of pulverised coal to adjust, to ensure that the ignition efficiency at the same time, but also to ensure that the ignition safety.
Among them, the wind powder refers to the mixture of wind and coal powder, and the pulverisedr 204953 coal ratio refers to the concentration size of coal powder therein.
The wind powder parameter adjustment method of the present embodiment automatically adjusts the wind powder parameter by combining the combustion process and the combustion data of each stage, which can ensure the timeliness of the adjustment of the wind powder parameter as well as the efficiency of the micro-oil ignition.

Specifically, through the real-time detection of wind powder parameters in various stages of data changes, in the wind powder parameter abnormalities, but also be able to manually intervene in a timely manner to adjust to ensure that the wind powder parameters can be the most suitable for micro-oil ignition, to ensure that the efficiency of micro-oil ignition. If the wind powder parameter corresponding to the ignition stage before the occurrence of the point is compared to the target wind powder parameter, the numerical relationship difference is large, indicating that there is an abnormality at present, and at this time, an alarm will be issued in a timely manner to ensure that the parameter adjustments are made in a timely manner to save fuel consumption.
Further, on the basis of the above embodiment, the present embodiment further comprises: calculating the current fuel consumption after the micro-oil ignition is successful; and storing the fuel consumption to the micro-oil ignition database.
