Abstract: Electrostatic spray technology provides a new method to improve combustion efficiency and decrease emis-sions for liquid fuePs spray combustion. Electrostfltic atomiza-tion principle of liquid particles is analyzed. A new kind of charging device of liquid fuel and a device of particle charge to mass ratio are developed. Experimental research on spray prop-erties of kerosene is carried on. The electrostatic spray field of kerosene is firstly investigated by PIV, Experimental results show that the kerosene' s atomizing quality and the field prop-erties of spay can be improved and ameliorated by charging.
