Abstract
The characteristic of the spiked electrode electrostatic precipitator was numerically studied. Complicated electrohydrodynamic flow was observed and vortices were formed in the ESP with the maximum gas velocity 30.9 m/s in this study. The spiked electrode had significant effects on the distribution of electric field and charge density. The corona charge was confined to six semi-ellipsoidal regions around the tips of the spiked electrode, which was 1.04 × 106 μC/m3 at the tip surface. The particle trajectories were complicated due to the EHD flow. High working potential and low gas velocity were beneficial to the removal of particles.
