Abstract— Some fundamental aspects of the electrostatic precipitator are investigated via a combination of tests in a high-voltage rig and numerical computations. The electric field and charge distribution in the duct are computed numerically using the commercially available FEM solver Comsol Multiphysics. The derived properties are compared with experimental data and general operating experience. Overall the agreement between numerical results and experiments is very satisfactory. The numerical solutions provide detailed insight into a number of basic phenomena governing the precipitator behaviour, and may give qualitative guidance also in the practical design of precipitators.
