What is ignition electrode？

   The ignition electrode is in the process of gas combustion, there are cations in the flame, when an external electric field is applied to the flame, the movement of the cations in the circuit will generate current. The flame ion current has obvious unidirectional conductivity. As the flame temperature increases, the current intensity also increases.

    During normal use, power is supplied to one end of the induction electrode. When the flame burns, many ions and electrons generated by the flame are attracted by the electric electrode, generating a weak current. At this time, the aluminum melting furnace burner shell is used as a ground electrode. After the weak current passes through the burner controller or the flame detector, the signal is expanded to control the heating of the solenoid valve in front of the burner. After the flame is extinguished, the current disappears and the solenoid valve is closed. control.
