摘要：

Charged water mist has been widely used in industrial dust controlling due to its charged characteristics. But the study for controlling fire is less. Therefore, in this paper, extinguishing experiments of kerosene fire was carried out with water mist which was charged by a corona discharge in a small-scale and confined space. Water mists with different charge-to-mass ratios was obtained by changing the voltage. The effects on extinguishing time, flame temperature and flame image changes were analyzed. The experiments show that the charged water mist can effectively reduce the extinguishing time, flame temperature and inhibit flame compared with the ordinary water mist. Additionally, the extinguishing efficiency significantly increases with the increase of charge-to-mass ratio. (C) 2014 Published by Elsevier Ltd.
