Precipitator Plate Imperfections and Eccentricities
Publication: Journal of the Energy Division
Volume 105, Issue 2
Abstract
Electrostatic precipitators are currently the key elements in air pollution control for coal-burning power generation plants, and their efficiency is highly related to the surface accelerations of their rapped collecting plate systems. The effect of minor plate imperfections and eccentricities in the suspension system on these surface accelerations is studied using standard linear dynamic finite element analysis as contained in the SAP-IV computer program. The in-plane and out-of-plane acceleration time histories for a typical point on a simplified numerical model of a suspended plate system are obtained for a variety of sinusoidal ripple imperfections of the plate surface and different hanging eccentricities. It is concluded that reasonable estimates of the maximum acceleration can be obtained without recourse to much more expensive nonlinear finite element analysis. Also, the qualitative effects of different imperfection and eccentricity details can be studied quickly and economically.
