[0063] Embodiment 1

[0064] This embodiment provides an industrial furnace ignition control method, which is applied to an industrial furnace ignition control system. The industrial furnace ignition control system includes: a burner, an igniter, such as Figure 1 As shown, it is a flow chart of the industrial furnace ignition control method provided in an embodiment of the present application, and the method comprises the following steps:

[0065] Step S101: obtaining an ignition instruction sent by a terminal device;

[0066] Step S102: controlling the igniter to ignite based on the ignition instruction;

[0067] Step S103: If it is detected that the igniter has ignited successfully, the burner gas solenoid valve of the burner is controlled to open after a preset time, so that the igniter ignites the burner, wherein the burner gas solenoid valve is used to control the opening or closing of the gas pipeline of the burner.

[0068] The industrial furnace ignition control method provided in the embodiments of this specification can be applied to the ignition and heating scenarios of various industrial furnaces in the steelmaking field, such as the ignition process of annealing furnaces, heating furnaces, bell-type furnaces, etc. For the sake of convenience, the embodiments of this specification mainly illustrate the present invention based on the ignition control process of annealing furnaces.

[0069] Before the ignition control of the industrial furnace is performed through the industrial furnace ignition control system, preliminary work can be performed first: the gas system is purged and released, wherein the gas system is used to provide the industrial furnace ignition control system with the gas required for ignition and continuous heating; after a period of time (15 to 30 minutes), one or more sampling gas pipelines are extracted for explosion test to detect the residual oxygen content in the pipeline; the ignition control system has air pipelines for conveying air and gas pipelines for conveying gas. If the residual oxygen content is qualified in the preset number of samplings, for example, after the residual oxygen content is qualified three times in a row, the manual valves of the air pipelines and gas pipelines in the ignition control system are opened to prepare for ignition.

[0070] Step S101: Obtain an ignition instruction sent by a terminal device.

[0071] The terminal device can be a system that combines a remote controller and a computer, such as a PLC (Programmable Logic Controller), a DCS (Distributed Control System), and other systems combined with a host computer. Specifically, take the example of a terminal device that is a combination of a DCS and a host computer: the operator sends an ignition command to the DCS through the host computer, and the DCS sends the ignition command to the ignition control system.

[0072] Step S102: Controlling the igniter to ignite based on the ignition instruction.

[0073] The ignition control system may be provided with a burner controller which is in communication connection with the terminal device. After obtaining the ignition instruction from the terminal device, the burner controller controls the igniter to ignite according to the ignition instruction.

[0074] Optionally, the igniter includes an ignition transformer, an ignition electrode and an igniter gas solenoid valve, the igniter gas solenoid valve is used to control the opening or closing of the gas pipeline of the igniter, and the ignition of the igniter based on the ignition instruction includes: controlling the ignition transformer to start so that the ignition electrode releases high voltage to generate electric sparks; controlling the igniter gas solenoid valve to open so that the gas released from the gas pipeline of the igniter is ignited by the electric sparks.

[0075] like Figure 2 As shown, it is a schematic diagram of the industrial furnace ignition control system provided in Example 1 of this specification. The igniter includes an igniter air pipeline for providing air, which is arranged at the rear end of the igniter port. An ignition electrode is arranged inside the igniter, and the ignition electrode is electrically connected to the ignition transformer, and the ignition transformer is electrically connected to the burner controller. The pipe openings of the igniter air pipeline and the igniter gas pipeline are both arranged at the ignition port of the igniter, so that the air in the igniter air pipeline and the gas in the igniter gas pipeline converge at the ignition port of the igniter and are further ignited. A normally closed igniter gas solenoid valve is arranged on the igniter gas pipeline.

[0076] During the specific implementation process, after receiving the ignition command, the burner controller can generate an ignition transformer start command, and send the ignition transformer start command to the ignition transformer, so that the ignition transformer starts and converts the power supply voltage into the secondary high voltage required for ignition, so that the ignition electrode releases high voltage, thereby generating an electric spark. On the other hand, the burner controller can also generate an igniter gas solenoid valve opening command and send it to the igniter gas solenoid valve to control the igniter gas solenoid valve to open, pass gas, and ignite the gas with an electric spark. Among them, the ignition transformer can be an electronic variable frequency oscillation high-voltage ignition transformer.

[0077] Step S103: If it is detected that the igniter has ignited successfully, the burner gas solenoid valve of the burner is controlled to open after a preset time, so that the igniter ignites the burner, wherein the burner gas solenoid valve is used to control the opening or closing of the gas pipeline of the burner.

[0078] Specifically, the ignition electrode can be selected according to actual requirements. An ignition electrode with only ignition function can be selected, and a detection device can be set on it to detect the igniter flame; an ignition and detection integrated ignition electrode can be selected. After the igniter is ignited, the igniter flame can be directly detected through the ignition electrode.

[0079] Taking the selection of the ignition electrode as an integrated ignition and detection type as an example, after the igniter is ignited, the ignition electrode will detect the igniter flame. The detection standard can be whether the temperature of the igniter flame reaches the preset temperature range, whether the frequency and intensity of the light energy emitted by the igniter flame reach the preset value range, and whether the image grayscale of the igniter flame and the size parameter value of the combustion contour meet the set value range, etc. If the igniter flame meets the detection standard within the preset time, the burner gas solenoid valve of the burner is controlled to open, the gas pipeline of the burner is opened, and gas and air are introduced. When encountering the igniter flame, it is ignited, that is, the burner is ignited; if the igniter flame does not meet the detection standard within the preset time, the igniter and the igniter gas solenoid valve are closed, and an igniter ignition failure signal is sent to the terminal device.

[0080] Take the detection standard of whether the temperature of the igniter flame reaches the preset temperature, the preset temperature range is 700-900℃, and the preset duration is 15s as an example: the flame detection device detects the temperature of the igniter flame. If the igniter flame temperature is detected to be stable at 800-890℃ within 15s, it means that the igniter flame meets the detection standard and the igniter ignites successfully. At this time, the burner gas solenoid valve that controls the burner is opened, the burner gas pipeline is opened, gas and air are introduced, and the burner is ignited through the igniter.

[0081] Optionally, after a preset period of time has passed, the burner gas solenoid valve of the burner is controlled to open so that the igniter ignites the burner, and the method further includes: detecting whether the burner is successfully ignited; if so, feeding back an ignition success signal to the terminal device and closing the ignition transformer; if not, feeding back an ignition failure signal and an alarm signal to the terminal device, and controlling the burner gas solenoid valve and the igniter gas solenoid valve to close.

[0082] like Figure 2As shown, a flame detector is provided at the burner mouth for detecting the burner flame, and the flame detector is communicatively connected with the burner controller. The rear end of the burner includes a burner air pipeline and a burner gas pipeline, and the pipe openings of the burner air pipeline and the burner gas pipeline are both provided at the burner mouth of the burner, so that the air in the burner air pipeline and the gas in the burner gas pipeline converge at the burner mouth and are further ignited by the igniter. A normally closed burner gas solenoid valve is provided on the burner gas pipeline, which is electrically connected with the burner controller.

[0083] It should be noted that Figure 2 The burner gas manual valve, burner air manual valve, igniter gas manual valve and igniter air manual valve are manual valves of each air pipeline and gas pipeline in the fore-work mentioned above. After the fore-work is completed, the staff first opens the burner air manual valve and the igniter air manual valve to pass air into the burner air pipeline and the igniter air pipeline; then opens the burner gas manual valve and the igniter gas manual valve to pass gas into the burner gas pipeline and the igniter gas pipeline.

[0084] After the igniter ignites the burner, the flame detector will detect in real time whether the burner flame is normal. Its detection standard is similar to the igniter flame detection standard, which will not be repeated here. If the burner flame meets the detection standard, the ignition transformer is turned off and an ignition success signal is sent to the terminal device. At this time, the igniter is not turned off; if the burner flame does not meet the detection standard, the burner gas solenoid valve and the igniter gas solenoid valve are turned off, and an ignition failure signal and an alarm signal are sent to the terminal device; if the burner flame meets the detection standard within the preset time, when the burner controller sends an ignition success signal to the terminal device, the burner flame does not meet the detection standard due to insufficient gas, insufficient air, system failure, etc., the burner controller first cuts off the ignition success signal sent to the terminal device, and then closes the burner gas solenoid valve and the igniter gas solenoid valve, and sends an ignition failure signal and an alarm signal to the terminal device.

[0085] Optionally, after feeding back the ignition failure signal and the alarm signal to the terminal device and controlling the burner gas solenoid valve and the igniter gas solenoid valve to close, the method further includes: if a reset instruction sent by the terminal device is detected, controlling the igniter to reignite; after the igniter successfully ignites, controlling the burner gas solenoid valve to reopen so as to ignite the burner through the igniter.

[0086] After the ignition of the igniter or burner fails, the operator can send a reset command through the terminal device to re-ignite the igniter and / or burner. The re-ignition method is the same as the ignition method of the above igniter and burner, which will not be repeated here. If the number of consecutive resets exceeds the preset number, the ignition control system needs to be repaired. The igniter and / or burner can be re-ignited only after the repair is completed. The preset number can be set according to the actual situation.

[0087] Optionally, the industrial furnace ignition control system includes a plurality of burners and a plurality of igniters, one igniter is provided for each burner, and the controlling the ignition transformer to start and the controlling the igniter gas solenoid valve to open include:

[0088] Based on a preset time interval, the ignition transformer and the ignition gas solenoid valve of each igniter are controlled to open in sequence to ignite the burner corresponding to each igniter.

[0089] The industrial furnace ignition control system provided in the embodiment of this specification can control the ignition of multiple burners in groups, such as Figure 3 As shown, it is a schematic diagram of the ignition control system for group ignition control of multiple burners. The terminal device is connected to each burner controller for communication. Each burner controller is connected to each burner in a group of burners respectively. One burner controller controls a group of burners.

[0090] In the specific implementation process, multiple burners can be divided into multiple groups. The number of burners in each group can be the same or different. Each burner has a corresponding igniter, and each group of igniters shares the same gas main line. When igniting each group of burners, in order to ensure the stability of the igniter, the burners are ignited one by one based on a preset time interval. Each time the igniter ignites a burner, a feedback signal of the burner ignition success is sent to the terminal device. After the preset time interval, the next burner is ignited by the next igniter. If an igniter fails to ignite the burner, all ignition success signals of the group are cut off, and the gas solenoid valves of all igniters in the group and all burners in the group are closed, and an ignition failure signal and an alarm signal are sent to the terminal device. Among them, the preset time interval can be 30 to 50 seconds.

[0091] For example, each group has three burners, A, B, and C, and burner A corresponds to igniter a, burner B corresponds to igniter b, and burner C corresponds to igniter c, and the preset time interval is 30s. A ignites A first. If it meets the detection standard, it sends an ignition success signal of A to the terminal device; after 30s, b ignites B. If it meets the detection standard, it sends an ignition success signal of B to the terminal device; after 30s, c ignites C. If it meets the detection standard, it sends an ignition success signal of C to the terminal device, and the ignition of the regrouped burners is completed. If the ignition of C by c does not meet the detection standard, the ignition success signals of A and B are cut off, and all the gas solenoid valves of the igniter and all the gas solenoid valves of the burners in the group are closed, and an ignition failure signal and an alarm signal are sent to the terminal device. After the ignition fails, the operator can send a reset command through the terminal device to re-ignite. The re-ignition method is the same as the above-mentioned ignition method of the igniter and burner, which will not be repeated here.

[0092] Optionally, the industrial furnace ignition control system further includes:

[0093] The burner control box is communicatively connected with the terminal device, the burner controller is arranged in the burner control box and connected with the burner control box, and the burner control box is used to locally control the burner controller to further ignite the industrial furnace.

[0094] Specifically, a burner control box can be set in the industrial furnace ignition control system provided in the embodiment of this specification. A remote / local switching switch and an ignition / extinguishing switch can be set on the burner control box. At the same time, power, operation, and alarm indicator lights, as well as a reset button are set for sending control instructions to the burner controller arranged in the burner control box.

[0095] The operator can use the remote / local switch to choose to remotely control the ignition of the igniter at the terminal device, or to locally control the burner controller at the burner control box to further ignite the industrial furnace. The ignition / extinguishing switch is used to control the opening and closing of the igniter gas solenoid valve and the burner gas solenoid valve; the power supply can be used to power the industrial furnace ignition control system; the operation and alarm indicator lights can be used to display the working status of the burner; the reset button can be used to re-ignite the igniter and / or burner.

[0096] The technical solutions in the above embodiments of the present invention have at least the following technical effects or advantages:

[0097] 1. Receive instructions through the burner controller and further control the industrial furnace ignition control system according to the instructions, which improves the safety of operators and reduces the workload of staff.

[0098] 2. Remote control of burner ignition can solve the inconvenience of on-site ignition operation for staff and environmental problems such as high on-site ambient temperature and harsh noise.

[0099] 3. Functions such as ignition success signal, ignition failure signal and alarm signal can enable staff to monitor the operating status of the industrial furnace ignition control system in real time, reducing the failure rate of the industrial furnace ignition control system.

[0100] 4. Group ignition automatic control greatly reduces manpower and material costs, and is more convenient, effective and reliable.
