The present invention relates to a plasma ignition device for directly igniting a pulverized coal burner. This plasma igniter includes a plasma generator having a composite anode, a combined cathode, an electromagnetic coil, and a transport coil, a multistage chamber for transporting ignited charcoal, an apparatus for adjusting the concentration of coal powder, and It consists of a pulverized coal burner with a staged burner canister and a generator brace. The combined cathode includes a cathode plate, a fixing nut, a conductive pipe, an inflow pipe, an inflow guide pipe, a cathode lid, and a sealing spacer. A lining for generating an electric arc is combined with the front of the cathode. An alloy plate is used as the cathode plate. The nozzle used to cool the cathode is divergent and is located in the middle of the conductive pipe. The plasma ignition device has an advantage of stable combustion. The plasma ignition device can be used not only as a main burner for a boiler but also as an ignition burner. Because no oil is used, a large amount of oil is saved. |
