| 摘要 | This invention relates to a plasma igniter for directly igniting the coal-powder furnace. Said plasma igniter consists of a plasma generator which includes a composite anode, an assembled cathode, an electromagnetic coil and a transmitting coil; a coal powder burner which comprises mutt-stage pipes for conveying igniting coal, an equipment for adjusting thickness of coal powder and a four-stage burner canister; and a generator brace. Said assembled cathode consists of a cathode plate, a fixation nut, a conductive pipe, a inflooding pipe, a inflooding guiding pipe, a cathode lid and a sealing spacer. The lining for generatoring electric arc is assembled with the front of cathode. An alloy plate is used as the cathode plate. The nozzle that used for cooling the cathode is first convergent and then expansive, and is placed in the middle of the conductive pipe. The plasma igniter has the advantage of stableburning. It can be used as not only a main burner for the boiler but also a igniting burner. Since oil is not used, lots of petroleum source is saved. | ||||||
