The control system of natural gas burner involves many aspects, and these key control elements also make the natural gas burner play its role better in the use process, let's introduce it below:

1. Ignition system: The ignition device of natural gas burner generally includes ignition electrode and igniter (with transformer or external). The voltage after the transformer is greater than 10kv, and the ignition electrode discharges high voltage to the ignition column to produce an electric spark to ignite natural gas.

2. Ignition protection system:It is completed by natural gas burner controller, solenoid valve and flame detection. The main flame detection methods are ultraviolet detection and electrode detection.

3. Stable combustion conditions: The basis of stable combustion is no fire and flashback. Flame stabilization measures must be taken in the design of natural gas burners. The burner uses a flame stabilizing disk to prevent this phenomenon.

4. High temperature mode: The high temperature mode of the burner controller is a working mode that disconnects the flame monitoring circuit and does not monitor the flame in real time. The prerequisite for this operating mode is that there are other means (such as temperature monitoring) to ensure the presence of the flame in the furnace.

5. Gas pressure control: Too high or too low gas pressure will affect the success rate of ignition and the stability of combustion. Therefore, it is necessary to maintain appropriate gas pressure by adjusting the gas pressure reducing valve.

6. Safety protection mechanism: Including gas leakage detection, overheating protection, flameout protection, etc., to ensure that the combustion can be stopped in time under abnormal conditions to prevent accidents.

7. Automatic control: Modern natural gas burners are usually equipped with automatic control system, which can realize remote monitoring and adjustment, improving the safety and convenience of operation.

To sum up, the control system of natural gas burner is a complex system engineering, which needs to comprehensively consider ignition, flameout protection, combustion stability, high temperature operation, gas pressure regulation, safety protection and automatic control.
