THREE PHASE ELECTRIC ARC HEATER
OF "ZVEZDA"-TYPE
(PLASMATRON, PLASMA TORCH)

The main advantages:

• Absence of a transformer and a rectifier

• High reliability

• High electrode lifetime

• Uniform load of three-phase network

• Uniform temperature distribution

Performance data:

• Input power 0.1 ... 40 MW

• Three-phase voltage 6 ... 10 kV

• Working gas Air (N2, Ar, He ...)

• Mass flow rate 0.1 ... 4 kg/s

• Maximum temperature 6000 K

• Pressure 0.2 ... 10 MPa

• Thermal efficiency, max 0.8

• Electrode lifetime at 200 A >500 h

The arc heater can be used for:

• Treatment of toxic wastes (such as trichlorethylene, methylchloride, polychlorbiphenyls, varnishes, lacquers, paints, etc.) and medical wastes;

• Plasma coating of the parts, tools etc;

• Micron powders making from the different metals.

• Production of basalt fibres
