This utility model relates to a boiler ignition device, including an igniter, a high-voltage ignition cable, an ignition rod, and a protective mechanism. The high-voltage ignition cable is installed on the surface of the igniter. Before ignition, the ignition cloth needs to be unfolded to fill the furnace inlet.
