Abstract
The utility model relates to a high energy igniter which is used for the ignition of various industrial furnaces which combust gas and oil. The high energy igniter comprises a power supply, a transformer, a rectifying circuit, a stored energy capacitor, an electric discharge tube and a spark plug. The high energy igniter is characterized in that a pulsed triggering circuit is connected in series between the stored energy capacitor and the electric discharge tube. One end of the pulsed triggering circuit is connected with the output end of the stored energy capacitor, and the other end is connected with the input end of the electric discharge tube. The output voltage of the stored energy capacitor is less than the breakdown voltage of the electric discharge tube. When the pulsed triggering circuit generates a high voltage pulse, and the electric discharge tube and the spark plug are broken down by the high voltage pulse, the stored energy capacitor discharges electricity to the spark plug, and strong sparks are generated. The pulsed triggering circuit can accurately control the ignition frequency of the igniter.
