We planed the experiment replacing the space structure of the premix fuel burner flame from the region of unburned gas to preheat zone with the time change of the pulse combustion phenomenon of the source gas from low-temperature oxidation reaction to ignition. We investigated the influence of propagation speed of flame kernel by laser ignition on dielectric barrier discharge. In the result, the propagation speed of flame kernel in dielectric barrier discharge become faster than in not dielectric barrier discharge.
