The development of a new recycling technology for waste concrete scraps becomes a big issue in Japan due to the increase of the scraps and the decrease of the natural coarse aggregates. In the present work, a new technology of concrete aggregates recycling using pulsed discharges was performed. A Marx generator was used as a pulsed power source and a point to hemisphere mesh configuration electrode...
In Japan, the treatment of waste concrete scraps has been one of the environmental issues. Therefore, the new application using pulsed power technology has been developed as the recycling method of coarse aggregates in waste concrete scraps. In the work, the dependences of the quality of the recycled coarse aggregate on the consumption energy and gap distance were investigated and the best condition...
Summary form given only. Pulsed power technology has been used in many applications such as control of NOx and SOx from exhaust gases, treatment of dioxins, removal of volatile organic compounds, generation of ozone and excitation of excimer laser. Since pulse duration of applied voltage to discharge reactor has a strong influence on energy efficiency of pollutants removal, the development of short...
The non-thermal, chemically active plasma is one of the promising technologies for the removal of the hazardous environmental pollutants. Pulsed streamer discharges in atmospheric pressure gases have received a great deal of interest for many years. It is very important to know the propagation mechanism of streamer discharges in order to improve the energy efficiency of pulsed discharge systems. In...
Presently, all the solid-state pulsed power generators have been developed for industrial applications, such as exhaust gases control, ozone generation, treatment of dioxins and laser excitation [1, 2]. However, miniature pulsed power generator which is suitable for portable applications, e.g. in a vehicle is rarely proposed. In this paper, a miniaturized pulsed power generator using a single-stage...
