The industrial electronic igniter introduced in this example has the characteristics of high ignition energy and low production cost, and can be used for starting ignition when burning fuel or gas in industrial oil furnaces and chemical and petroleum fields. The industrial electronic igniter circuit is composed of a power supply circuit, a starting ignition control circuit and a boost ignition circuit. When the ignition control button S2 is pressed, C5 starts charging, and the NAND gate D3 outputs a low level, and D1 and D2 output a high level. The VT is triggered to conduct, the KA is energized, and its normally open contact is connected to the working power of the boost ignition circuit. AC 220V voltage is rectified by T boost, VD2 ~ VD5, and C3 is charged through R2. When the voltage across C3 reaches the breakdown voltage of the discharge tube, the discharge tube breaks down, and the electric energy stored on C3 is applied to the spark plug through the discharge tube and the inductor L, and a spark is generated through the spark plug to ignite the fuel or gas.
