| Abstract |
|
Effects of operating parameters on electrical properties and ozone generation of Plasma Gun for ballast water treatment were investigated in a laboratory scale experiment. Electrical discharges and ozone generation initiated with applying voltages higher than discharge onset value. Ozone concentration was almost linearly increased with the increase of applied voltage. The optimum electrode gap distance which gave the optimum energy efficiency of ozone generation was 1.95 mm in the experimented apparatus. The effect of inner
electrode material on the electrical energy transfer was negligible, however, the difference of electrical and thermal conductivities between electrode materials significantly influenced the ozone generation. In a constant geometrical structure, the electrical energy density played an important role in the ozone generation. The increase of oxygen content in the feeding gas enhanced the ozone generation by lowering ionization potential and promoting ozone source. |
