Preferably, in order to avoid that the ignition gas pipeline 112 cannot be closed after the boiler 200 is successfully ignited due to the failure of the third electromagnetic valve 155, a fourth electromagnetic valve 156 is further disposed at the ignition gas pipeline 112 to form a double-cut protection for the ignition gas pipeline 112, so as to ensure that the ignition gas pipeline 112 can be closed after the boiler 200 is successfully ignited. In the illustrated embodiment, the fourth solenoid valve 156 is disposed between the third solenoid valve 155 and the pressure gauge 145. It will be appreciated that the specific position of the fourth solenoid valve 156 may be determined as desired.
A flow regulating valve 151, such as an electromagnetic regulating valve, is provided at a position of the main gas pipe 111 adjacent to the burner 130 for regulating the amount of the main gas introduced into the burner 130 during the operation of the boiler 200, thereby regulating the operation load of the boiler 200.
The opening and closing of the main gas pipe 111 is mainly achieved by the first solenoid valve 153 provided at the main gas pipe 111. In the illustrated embodiment, the first solenoid valve 153 is disposed upstream of the flow rate adjustment valve 151.

The first pressure transmitter 142 and the flow meter 143 may be electrically connected to the remote control device to transmit the measured pressure value and flow value of the gas in the gas supply pipeline 114 to the remote control device, so that an operator can remotely obtain the corresponding pressure value and flow value.
In order to provide fresh air to the burner 130 for mixed combustion with the gas during ignition and operation of the boiler 200, a fan 160 is provided in communication with the burner 130 in the vicinity thereof. The fan 160 may specifically include a blower and an induced draft fan. The blower is used for supplying air to the boiler 200, i.e., supplying air to the burner 130; the induced draft fan is used for introducing the flue gas discharged by the boiler 200 into the combustor 130 for remixing combustion, so as to reduce the content of nitrogen oxides discharged into the atmosphere by the boiler 200, and make the content meet the national emission standard. The blower 160 may be activated locally or may be electrically connected to a remote control device and activated by receiving a command from the remote control device.
Furthermore, it is right to design the internal structure of the burner 130 of the preferred embodiment of the present invention, so that the gas and the fresh air enter the furnace 200 of the boiler through different channels, and the ratio of the gas and the air volume entering the furnace 200 of the boiler is adjusted by the structure of the mechanical design channel, so that the gas is fully combusted, the effect of the low content nitrogen oxide discharged from the boiler 200 is achieved, and the discharge amount of the nitrogen oxide is reduced to 47.39mg/m3。
The success or failure of the ignition of the boiler 200 can be detected by the flame detection device 170. Specifically, the flame detection device 170 is disposed at the burner 130, such as mounted on a panel of the burner 130. The flame detection device 170 is preferably an ultraviolet/infrared integrated flame detection device, so that both infrared light and ultraviolet light can be detected, thereby improving the accuracy of the detection result. The flame detection device 170 may also be electrically connected to a remote control device to transmit the detection result to the remote control device, so that an operator can obtain the corresponding detection result remotely.
Preferably, the flame detection means 170 may be provided in plural, such as three, to prevent it from being difficult to judge whether ignition is successful or not when the flame detection means 170 is damaged. It will be appreciated that the specific number of flame detection devices 170 may be determined as desired, so long as the success or failure of ignition can be accurately detected.
In addition, in order to ensure safe ignition and operation of the boiler 200, a flame arrester 180 is further provided at an inlet of the burner 130, for preventing gas entering a furnace of the boiler 200 from flowing backwards into the gas pipe 110 to cause a safety accident.
According to the utility model discloses a process that combustor high energy discharge ignition device 100 igniteed boiler 200 is as follows:
before ignition, the remote control device starts the blower in the fan 160 to supply air, and the opening of the blower is opened at a small position to prevent the flame of the burner 130 from being blown out during ignition. Then, the first, second, and third regulating valves 157, 158, and 159 are opened, and the fuel gas from which impurities have been removed by the filter 190 is introduced into the fuel gas pipe 110. At this time, the first pressure transmitter 142 may monitor the pressure of the gas in the gas supply pipeline 114 in real time, and if the pressure value of the gas measured by the first pressure transmitter 142 is lower than the set pressure value, which indicates that the gas pressure is too low, the ignition procedure needs to be closed. It should be noted that, even during the combustion operation of the boiler 200, as long as the pressure value of the combustion gas measured by the first pressure transmitter 142 is lower than the set pressure value, the operation procedure of the boiler 200 is immediately terminated to perform the function of full protection.
Since the fuel gas entering the fuel gas pipe 110 is a colorless, odorless, toxic and harmful gas, it is necessary to detect whether the fuel gas pipe 110 and the valve assembly are leaking before ignition for safety.
Whether the gas pipeline 110 leaks gas is mainly detected by the gas alarm instrument 141. After the gas pipeline 110 is filled with gas, if the gas alarm instrument 141 gives an alarm, it is indicated that there is a place where gas leaks from the gas pipeline 110, and an alarm prompt is correspondingly given on a display interface of the remote control device to remind an operator to go to on-site inspection, and after the treatment is finished, the next ignition procedure is performed.
For detecting whether the valve assembly leaks, the airtightness of the first electromagnetic valve 153 and the second electromagnetic valve 154 of the main gas pipeline 111 is mainly detected, so as to prevent the airtightness of the first electromagnetic valve 153 and the second electromagnetic valve 154 from being poor, and thus gas from leaking into the boiler 200. In order to detect the airtightness of the first solenoid valve 153 and the second solenoid valve 154, a second pressure transmitter 144 is further provided at the main gas pipe 111 therebetween. Here, it should be noted that the air tightness detection of the first solenoid valve 153 and the second solenoid valve 154 is automatically performed by a control program of the remote control device. The leak detection process comprises the following steps:
the first solenoid valve 153 and the second solenoid valve 154 on the main gas pipe 111 are closed, and the fourth regulating valve 161 on the drain pipe 113 is opened. The fourth regulating valve 161 is opened for 5S and then closed, and the pressure value of the second pressure transmitter 144 should be 0. 5S, observing the pressure value of the second pressure transmitter 144, and if the pressure value is lower than the pressure value set by the program, indicating that the first electromagnetic valve 153 is airtight; if the pressure value of the second pressure transmitter 144 is higher than the programmed pressure value, it indicates that the first solenoid valve 153 is leaking. At this time, the ignition process is turned off, and the reason for the leakage of the first solenoid valve 153 is checked.
If the first electromagnetic valve 153 is detected to be air-tight, the remote control device closes the fourth adjusting valve 161 on the emptying pipe 113, opens the first electromagnetic valve 153 after 2S, and the gas enters between the fourth adjusting valve 161 on the emptying pipe 113 and the second electromagnetic valve 154, at this time, the pressure value of the second pressure transmitter 144 is equal to the pressure value of the first pressure transmitter 142. The first solenoid valve 153 is opened for 2S and then closed. The pressure value of the second pressure transmitter 144 is observed after 5S. If the pressure value of the second pressure transmitter 144 is not lower than the programmed pressure value, it indicates that the second solenoid valve 154 is airtight; if the pressure value of the second pressure transmitter 144 is lower than the programmed pressure value, it indicates that the second solenoid valve 154 is leaking. At this time, the ignition process is turned off, and the second solenoid valve 154 is checked for the reason of air leakage.
After successful leak detection of the first solenoid valve 153 and the second solenoid valve 154, the remote control device will simultaneously open the third solenoid valve 155 and the fourth solenoid valve 156, and the gas will enter the burner 130 through the ignition gas pipe 112. Meanwhile, the remote control device will send a start command to the high-energy discharge control box 120, and the high-energy discharge control box 120 will discharge 15S, so that the high-energy ignition gun tip 131 ignites the gas. At this time, the flame detection device 170 performs flame detection and feeds back a detection signal to the remote control device. The remote control device will perform one-out-of-three determination on the flame detection signals of the three flame detection devices 170. That is, if only one flame detection device 170 detects a flame signal, it indicates that the gas ignition is successful. If none of the three flame detection devices 170 detect a flame signal, a misfire is indicated. The remote control will close both the third solenoid valve 155 and the fourth solenoid valve 156 simultaneously to restart ignition.
After the ignition gas pipe 112 is ignited successfully, the remote control device closes the fourth regulating valve 161 on the emptying pipe 113 and opens the first electromagnetic valve 153 and the second electromagnetic valve 154 on the main gas pipe 111 to open the main gas pipe 111. Initially, the opening of the flow rate control valve 151 is relatively small, about 10%, and the main fuel gas enters the burner 130 through the main fuel gas pipe 111 to be supplied to the main fire. At this time, the flame detection device 170 performs flame detection and feeds back a detection signal to the remote control device. The remote control device will make a two-out-of-three determination on the flame signals of the three flame detectors 170. That is, if two flame detection devices 170 detect a flame signal, it indicates that the fire is successfully applied. The remote control will close both the first solenoid valve 153 and the second solenoid valve 154 on the ignition gas duct 112 simultaneously. The operator adjusts the load of the boiler 200 by adjusting the flow rate adjustment valve 151. After the load of the boiler 200 is stabilized, an operator can start the induced draft fan in the fan 160 through the remote control device to redirect the flue gas at the tail of the boiler 200 to the burner 130 for combustion, thereby reducing the content of nitrogen oxides in the emission.
If only one of the three flame detection devices 170 detects a flame signature, or none of the three detects a flame signature, then a failure to initiate the main fire is indicated. The remote control will close the second solenoid valve 154 and the third solenoid valve 155 simultaneously and open the fourth regulating valve 161 on the evacuation pipe 113 to evacuate the residual gas in the main gas pipe 111. The ignition sequence is then restarted.
