Multi-electrode Designed Shape for Small Scale Plasma Incinerator

Currently electronic waste has increased due to the growth of an industrial economy. Conventional method of waste destruction was to use burner that heats up and finally forming hydrocarbon to an atmosphere. Recently, plasma technology is an alternative method that has an efficiency and safe to use as a mean for waste destruction due to its higher temperature. This research is an improvement design of electrodes tip used for plasma head assembly using small scaled power supply. The designed shape and materials such as graphite, steel and tungsten were simulated and used to evaluate the generated plasma. In addition, electrode designed group were compared for a current density and current distribution from a simulation which will also determine for a plasma length, temperature and durability of material on actual experimental. Electrode shape was designed with sharp cornered that has cross sectional area indicated that it has highest current distribution at the tip of electrode surface. Based on the simulation results, the proposed designed electrode was capable of highest current density when compared with others. The simulated and experimental results have been shown to agreed well for plasma length and temperature.
