Self-Cleaning, Economic and Energy Efficiency Arc Plasma Torch for Materials Processing

G. Gelenidze, Mining Institute, Tbilisi, Georgia; F. D. S. Marquis, Naval Postgraduate School, Monterey, CA

In work it is submitted arc plasma torches, cooled by evaporations heat of water filled in arc plasma torch (0.2-0.4 kg). Allocated thus of pairs water it is used for formation of a jet of plasma. Advantages of this kind arc plasma torches are: 1. Is absent external water supply and gas supply, which is ensured by development of self-cooled and stabilizing arc plasma torch eliminating necessity of an external water supply and gas supply, 2. Ecological cleanliness is excluded formation of harmful gases (NO, CO) and allocation pair a process able material decreases, which is ensured by them, that the plasma jet forming gas, instead of air, is formed by the steam, getting at cooling of units of arc plasma torch; 3.Energy-efficiency of the plasma torch -that is ensured by development of arc plasma torch in which the heat taking off from arc plasma torch for cooling is reverted in a plasma jet. Thus the Energy - efficiency of arc plasma torch is increased on 10-15 %; The following types of self-cleaning arc plasma torches are developed: 1.Arc plasma torches direct action for processing metal products; 2.Arc plasma torches indirect action for processing not metal products; 3.Arc plasma torches with the free arc blown own ferry of water, in exchange argon torches; 4. Arc plasma torches with a free arc for dividing are sharp metals instead of electro arc are sharp metals. Field of application: 1.Metal working industry; 2. Small enterprises and house hold conditions; 3.Mounting and repair of the sanitary equipment; 4. Mounting both repair of mains pipelines and pipelines of different technological purpose; 5. Processing building materials: cutting, glazing and art processing; 6.Auto or truck service and repair; 7. Factory and farm maintenance; 8. Cutting of reinforced-concrete items of the fallen off buildings both structures at terrorist enters.

Summary: In work it is submitted arc plasma torches, cooled by evaporations heat of water filled in arc plasma torch. Allocated thus of pairs water it is used for formation of a jet of plasma. Advantages of this kind arc plasma torches are: 1. Is absent external water supply and gas supply, 2. Ecological cleanliness is excluded formation of harmful gases (NO, CO) and 3. The energy - efficiency of arc plasma torch is increased on 10-15 %.
