[0040] In some cases, the key to achieving ideal combustion lies in that the combustion control system can accurately adjust the combustion parameters in proportion. However, currently most combustion control systems still rely on manual operation, and the adjustment of parameters mainly depends on the experience and intuition of technicians, which often makes it difficult to achieve the ideal combustion effect. At the same time, although some high-end control systems achieve automatic adjustment of proportional combustion by integrating high-precision instruments such as flow meters, there is a problem of low economic applicability and it is difficult to be widely used.

[0041] Based on the above situation, the present application proposes a combustion control system, aiming to dynamically adjust the combustion ratio to ensure the stability and efficiency of the combustion process.

[0042] The following further elaborates on each embodiment of the combustion control system of the present application with reference to the drawings.

[0043] As Figure 1 and Figure 2 shown, Figure 1 is a schematic structural diagram of a combustion control system provided by an embodiment of the present application, Figure 2 is a schematic structural diagram of a combustion control system provided by another embodiment of the present application.

[0044] In one embodiment, the combustion control system of the embodiment of the present application includes a first temperature transmitter 100, a first electric actuator 200, a first pressure transmitter 300, a second temperature transmitter 400, a second electric actuator 500, a second pressure transmitter 600, and a burner 700.

[0045] Exemplarily, the burner 700 is provided with a gas path and an air path. The first temperature transmitter 100, the first electric actuator 200, and the first pressure transmitter 300 are connected in sequence and arranged in the gas path. The second temperature transmitter 400, the second electric actuator 500, and the second pressure transmitter 600 are connected in sequence and arranged in the air path.

[0046] Exemplarily, the first temperature transmitter 100 is used to obtain the gas temperature of the gas path, the first pressure transmitter 300 is used to obtain the gas pressure of the gas path, the second temperature transmitter 400 is used to obtain the air temperature of the air path, and the second pressure transmitter 600 is used to obtain the air pressure of the air path.

[0047] Exemplarily, the embodiment of the present application can adjust the valve opening of the first electric actuator 200 or the second electric actuator 500 according to the obtained gas temperature, gas pressure, air temperature, air pressure, and preset proportional relationship, so that the air pressure, air temperature, gas temperature, and gas pressure conform to the preset proportional relationship.

[0048] It should be noted that since the present application can adjust the flow rate of the gas path or the air path according to the obtained gas temperature, gas pressure, air temperature, air pressure, and preset proportional relationship, it can achieve dynamic adjustment of the combustion ratio to ensure the stability and efficiency of the combustion process.

[0049] Exemplarily, when the gas pressure changes, the gas density in the gas path will change accordingly, resulting in a change in the gas flow rate. If the air pressure and flow rate do not change accordingly, the air-fuel ratio cannot be maintained in the optimal state. Therefore, the embodiment of the present application can control the valve opening of the second electric actuator 500 according to the gas pressure, gas temperature, air temperature, and preset proportional relationship, so as to adjust the air flow rate in the air path, and further achieve precise control of the mixing ratio of gas and air to achieve an almost ideal air-fuel ratio.

[0050] Exemplarily, when the air pressure changes, the air density in the air path will change accordingly, resulting in a change in the air flow rate. If the gas pressure and flow rate do not change accordingly, the air-fuel ratio cannot be maintained in the optimal state. Therefore, the embodiment of the present application controls the valve opening of the first electric actuator 200 according to the air pressure, air temperature, gas temperature, and preset proportional relationship, so as to adjust the gas flow rate in the gas path, and further achieve precise control of the mixing ratio of gas and air to achieve an almost ideal air-fuel ratio.

[0051] Exemplarily, when the air temperature changes, the air pressure also changes accordingly, resulting in a change in the air flow rate, which will cause the air-fuel ratio not to be maintained in the optimal state. Therefore, the embodiments of the present application can control the valve opening of the first electric actuator 200 according to the air pressure, air temperature, gas temperature, and preset proportional relationship, so as to be able to adjust the gas flow rate in the gas path, and further ensure that the air-fuel ratio is in the optimal state.

[0052] Exemplarily, when the air path starts to work, it is at normal temperature and pressure. Due to the improvement of waste heat utilization efficiency, the temperature of the air rises to 100-200°C, and the air pressure and flow rate of the air path also change accordingly, resulting in the air-fuel ratio not being maintained in the optimal state. Thus, the valve opening of the first electric actuator 200 is controlled according to the air pressure, air temperature, gas temperature, and preset proportional relationship, so as to be able to adjust the gas flow rate in the gas path, and further ensure that the air-fuel ratio is in the optimal state.

[0053] Exemplarily, when the air temperature changes, the air pressure also changes accordingly, resulting in a change in the air flow rate, which will cause the air-fuel ratio not to be maintained in the optimal state. Therefore, the embodiments of the present application can control the valve opening of the second electric actuator 500 according to the gas temperature, gas pressure, air temperature, and preset proportional relationship, so as to be able to adjust the air flow rate in the air path, and further ensure that the air-fuel ratio is in the optimal state.

[0054] Exemplarily, when the air path starts to work, it is at normal temperature and pressure. Due to the improvement of waste heat utilization efficiency, the temperature of the air rises to 100-200°C, and the air pressure and flow rate of the air path also change accordingly, resulting in the air-fuel ratio not being maintained in the optimal state. Thus, the valve opening of the second electric actuator 500 is controlled according to the gas temperature, gas pressure, air temperature, and preset proportional relationship, so as to be able to adjust the air flow rate in the air path, and further ensure that the air-fuel ratio is in the optimal state.

[0055] Specifically, in one embodiment, the combustion control system further includes a first pressure gauge 800 and a pressure regulating valve 900.

[0060] Specifically, in one embodiment, the combustion control system further includes a safety cut-off assembly 1100.

[0061] Exemplarily, the safety cut-off assembly 1100 is disposed between the second pressure gauge 1000 and the first electric actuator 200.

[0063] Exemplarily, the low-pressure switch 1110, the first safety cut-off valve 1120, the leak detection switch 1130, the second safety cut-off valve 1140, and the high-pressure switch 1150 are connected in sequence.

[0064] Exemplarily, the low-pressure switch 1110 is also electrically connected to a controller (not shown in the figure). When the reading of the low-pressure switch 1110 is less than a preset low-pressure threshold, the low-pressure switch 1110 sends a low-pressure signal to the controller, and the controller sends a closing instruction to the first safety cut-off valve 1120 and the second safety cut-off valve 1140 according to the low-pressure signal. By setting the low-pressure switch 1110, the gas path is closed when the pressure in the gas path is too low, avoiding damage to the gas path caused by too low pressure and improving the service life of the combustion control system.

[0065] Exemplarily, the leak detection switch is also electrically connected to the controller. When the reading of the leak detection switch is greater than a preset pressure change threshold, the leak detection switch sends a leakage signal to the controller, and the controller sends a closing instruction to the first safety cut-off valve 1120 and the second safety cut-off valve 1140 according to the leakage signal. By setting the leak detection switch, the gas path is closed when the gas pressure change in the gas path is too large, avoiding production accidents caused by gas leakage and ensuring the safety of the combustion control system.

[0066] Exemplarily, by setting the first safety cut-off valve 1120 and the second safety cut-off valve 1140, it is convenient to quickly close the gas path when a gas leakage occurs in the gas path, avoiding excessive gas leakage into the environment and affecting the safety of the combustion control system.

[0067] Exemplarily, the high-pressure switch 1150 is also electrically connected to the controller. When the reading of the high-pressure switch 1150 is greater than the preset high-pressure threshold, the high-pressure switch 1150 sends a high-pressure signal to the controller, and the controller sends a closing instruction to the first safety cut-off valve 1120 and the second safety cut-off valve 1140 according to the high-pressure signal. By setting the high-pressure switch 1150, the gas path is closed when the pressure in the gas path is too high, avoiding damage to the gas path caused by excessive pressure and improving the service life of the combustion control system.

[0068] Specifically, in one embodiment, the combustion control system further includes a third pressure gauge 1200.

[0069] Exemplarily, the third pressure gauge 1200 is connected to the first pressure transmitter 300. By setting the third pressure gauge 1200, the gas pressure entering the burner can be obtained in real time.

[0070] Specifically, in one embodiment, the combustion control system further includes a first manual regulating valve 1300.

[0071] Exemplarily, the first manual regulating valve 1300 is arranged between the first pressure transmitter 300 and the third pressure gauge 1200. By setting the first manual regulating valve 1300, it is convenient to adjust the pressure in the gas path manually, improving the convenience of use and control accuracy of the combustion control system. At the same time, the first manual regulating valve 1300 can also adjust the pressure in the gas path when all the electric regulating valves such as the first electric actuator 200, the first safety cut-off valve 1120, the second safety cut-off valve 1140, and the pressure regulating valve 900 fail, ensuring the safety of the combustion control system.

[0072] Specifically, in one embodiment, the combustion control system further includes an air pressure switch 1400, which is connected to the second temperature transmitter 400.

[0073] Exemplarily, the air pressure switch 1400 is also electrically connected to the controller. When the reading of the air pressure switch 1400 exceeds the preset air pressure range, the air pressure switch 1400 sends an air pressure signal to the controller, and the controller sends a closing instruction to the second electric actuator 500 according to the air pressure signal. By setting the air pressure switch 1400, the air path is closed when the pressure in the air path is too high or too low, avoiding damage to the air path caused by excessive or too low pressure and improving the service life of the combustion control system.

[0074] Specifically, in one embodiment, the combustion control system further includes a fourth pressure gauge 1500, which is connected to the second pressure transmitter 600.

[0075] Exemplarily, by setting the fourth pressure gauge 1500, the air pressure entering the burner can be obtained in real time.

[0076] Specifically, in one embodiment, the combustion control system further includes a second manual regulating valve 1600.

[0077] Exemplarily, by setting the second manual regulating valve 1600, it is convenient to adjust the pressure in the air path manually, improving the convenience of use and control accuracy of the combustion control system. At the same time, the second manual regulating valve 1600 can also adjust the pressure in the air path when the second electric actuator 500 fails, ensuring the safety of the combustion control system.
