Burner ignition control is a key link to ensure the safe and efficient operation of industrial combustion systems. The following are several important aspects of burner ignition control based on the provided search results:

1. Controller selection and configuration

Selecting the appropriate burner controller is crucial for ignition control. For example, the IES258-5/1W burner automatic controller is a direct start and monitor for burner operation, suitable for systems that do not use purge or where purge is controlled by other systems, with direct ignition power not exceeding 350KW and auxiliary combustion air. The technical specifications of the controller include power supply, ambient temperature, flame detection current, protection rating, and ignition cable length, all of which need to be selected and configured according to specific application scenarios.

2. Line inspection and debugging

During the ignition control process, proper wiring inspection and debugging are fundamental to ensuring successful ignition. This includes checking whether the live wire L1 and neutral wire N, as well as other lines, are connected according to specifications. After confirming everything is correct, close the manual valve, start the system, and turn on the switch on the burner controller panel. When the green light comes on, turn on the ignition switch to power terminal 3. Initiate the operation program; after about 3 seconds, the gas solenoid valve opens, igniting the burner. After a safety period, the burner controller will issue a fault signal, causing the red light on the panel to turn on. Close terminal 8 and 9, open the manual valve, reset the controller to clear the fault signal, and restart the operation program for the system to return to normal.

3. Adjust the flame monitoring current

The adjustment of the flame monitoring current is also a critical point in ignition control. The flame monitoring current can be adjusted between 2uA and 20uA. To adjust it, loosen the controller's mounting bolts, remove the controller from the base, and adjust the potentiometer on the small board to the desired position. It should be noted that the monitored current on the panel should be at least 3uA higher than the set value.

4. Safety precautions

In the process of ignition control, safety is the primary factor to consider. For example, when maintenance is required, the power supply must be cut off. Only professionals can analyze and deal with accidents. Do not remove the labels on the equipment without authorization, otherwise the warranty will be invalid. Improper damage caused by unauthorized repair and wiring errors is not within the scope of warranty.

5. Control of deflagration phenomenon

Deflagration may occur during ignition, which is a potential danger to the furnace operator. Deflagration can be effectively controlled, and burner designers need to analyze from an Angle to understand more deeply the causes of this phenomenon, so as to take measures to prevent it.

The above is a summary of the key points of burner ignition control. It should be noted that different application scenarios may require different control strategies and technical parameters, so appropriate choices and adjustments should be made according to the specific situation in actual operation.
