A consumable set is provided that is usable in a plasma arc torch to direct a plasma arc to a processing surface of a workpiece. The consumable set comprises a nozzle and an alignment surface. The nozzle includes: 1) a nozzle body defining a longitudinal axis extending therethrough, and 2) a nozzle exit orifice disposed in the nozzle body for constricting the plasma arc. The nozzle exit orifice defines an exit orifice axis oriented at a non-zero bevel angle relative to the longitudinal axis. The alignment surface is generally parallel to the exit orifice axis and dimensioned to align the exit orifice such that the plasma arc impinges orthogonally on the processing surface of the workpiece. The alignment surface is configured to lay at least substantially flush against a guiding surface angled relative to the processing surface of the workpiece.

A plasma gas water ionization purification system that purifies waste water into clean water by removing inert waste solids from the waste water. The plasma gas water ionization purification system includes an ionization chamber and a plasma emitting device. The ionization chamber receives the waste water. The plasma emitting device is operatively connected to the ionization chamber and generates a stream of plasma to heat the waste water in the ionization chamber to generate purified steam from the waste water, thereby resulting in separation of the purified steam from the inert waste solids in the waste water, with the purified steam then being condensed into liquid form forming the clean water, which is collected for later use.

A plasma generation device includes one electrode, a nozzle case made of a conductor and having a cylindrical internal space, a nozzle made of a conductor, installed rotatably about a central axis of the internal space of the nozzle case, and configured to eject generated plasma gas, a fluid supply device configured to supply a fluid into the internal space, a rotation mechanism made of an insulator and configured to rotate the nozzle by the fluid supplied from the fluid supply device, a conductive path formed between the nozzle case and the nozzle, and a power supply configured to apply a voltage to the electrode, in which the nozzle case is grounded, and the plasma gas is generated by a potential difference between the electrode to which a voltage is applied by the power supply and the nozzle grounded by the conductive path.
