An electric arc plasma torch and an application method thereof. The torch comprises a cathode, an anode, a torch barrel, and a rear base. The rear end of the torch barrel is connected to the rear base forming a torch body; the cathode is connected to the front end of the torch barrel wherein an annular space forms a torch nozzle; a space in the torch barrel forms a gas chamber; the rear base forms a closed end at the rear of the torch barrel; the front end of the anode extends into the torch barrel via a through hole on the rear base, a space between the front end of the anode and of the cathode forms an electrical discharge space; the rear portion of the anode body is outside of the torch body; a service water interface is connected from the outside of the torch body into a cooling chamber of the anode. The application method is as follows: using water as a coolant of the anode and of the cathode of the arc plasma torch, then vaporizing the water into water vapor, using the vaporization latent heat to absorb heat from the anode and the cathode, avoiding or slowing anode and cathode ablation; then using the water vapor as a service gas or an object to be heated, forming an activated chemical by means of electric field ionization, decomposition, and activation, and spraying into a gasification chamber to have a chemical reaction with carbon forming synthesized gas.
