To improve the safety and reliability of local ventilation of heading face in the coal-mine and prevent gas accumulation effectively, the paper develops a flameproof 660V- high power three-phase emergency power supply (EPS) for auxiliary fan in the mine. The paper illustrates the design and implementation of the battery system which is the core of the EPS, including the design of constitution of high-voltage...
Bipolar pulsed discharge in the Gas-liquid-solid mixture was studied using a packed bed plasma reactor with gas bubbling. Effect of different packings on the treatment performance was investigated. Light emission and the active species formed during the discharge process were measured. Experimental results proved that bipolar pulsed discharge in the packed bed reactor with gas bubbling had a good...
Plasma-facilitated selective catalytic reduction (PF-SCR) is an effective way for automobile exhaust treatment. Pellets size of the packed bed plasma reactor has important effect on treatment efficiency. This paper aims to investigate the effect of particles size on the treatment efficiency using a pecked bed plasma rector powered by ac high-voltage power at 50 Hz. Electric distribution of the packed...
