Class 39(i) Apparatus for electrostatically precipitating charged suspended particles from a fast-moving gas stream comprises an elongated casing having inlet duct 1, Fig. and outlet 3, porous partition 2 through which the flows in direction normal to general of flow; area is large compared with cross-sectional so that speed flow low longitudinal flow. A non-discharging electrostatic field established between opposite wall 5 forms particle collecting surface. As shown 8 conical similarly shaped casing. wire 10, forming discharge electrode charging passes down middle 6, attached apex insulator 11. The unit may be cylindrical form or hexagonal cross-section, several units arranged parallel. consist gauze backed by steel wool, perforated metal sheet. porosity preferably decreases end According Provisional Specification flattened form, number electrodes are provided. Further, reversed, plate being provided centre unit.
