Abstract: An AC plasma ejection gun, the method for supplying power to the gun and a pulverized coal burner are provided. The ejection gun comprising: a power supply device, having a live wear and a null wear; an electric front electrode, inside of which a front chamber is set, a nozzle connected with said front chamber is set at the outlet of the front electrode, an air inlet pipe connected with said front chamber is set at the inlet of the front electrode, and the front electrode is connected with said null wire; an electric rear electrode, connected with the inlet of said front electrode by an insulated ring, there is a gap between the electric rear electrode and said front electrode, said rear electrode is connected with the live wire, a spinning air inlet ring is set at the outside of the gap between said front electrode and said rear electrode, compressed air from the air inlet pipe passes the spinning air inlet ring and enters into the front chamber; wherein, the arc between said front electrode and said rear electrode discharges, ionizing the compressed air into plasma in the gap between said front electrode and said rear electrode, and the plasma is ejected out of the nozzle from the front chamber. The ejection gun in present invention can work with small current and large power, so that the life of the plasma ejection gun is prolonged.
