Abstract

The new spray system is proposed by using a pipe with hygroscopic needle electrode In order to develop an air-cleaning ESP with high collection efficiency for submicron particles and high removal efficiency for NOx, SO$_2$, NH$_3$. Fundamental characteristics of charging water spray, which is not an usual wet type, are investigated experimentally. As a result, corona discharging mode and ozone generation rate are significantly affected by the operational conditions, such as the applied voltage and wet condition of the needle electrode.
