The paper discusses a system of integral particle charging and collection in a combined electric and flow field that has been developed to provide pressure drop reductions that are larger than previously reported in electrified fabric filtration. A mathematical model has been developed that predicts the nonuniform deposition that results and the relative pressure drop as compared to conventional nonelectrified filtration. The paper gives the background in applying electrostatics to fabric filtration. It discusses the technique for integral particle charging and collection in a combined electrical field. It describes an experimental program that would provide the data needed to prepare a mathematical engineering design model. Measurements of areal density, drag, thickness, and dust cake bulk density were made upon particle layers deposited on fabric filters with integral particle charging and collection with a combined electric and flow field.
