Abstract: Electrostatic precipitator apparatus for cleaning a particle-laden gas flowing therethrough including a shell with a gas inlet duct and outlet duct, spaced collector electrodes suspended within the shell defining gas passages therebetween, discharge electrodes suspended within the gas passages for ionizing particles in the gas for collection by the collector electrodes, and hoppers suspended below the collector electrodes for collecting the particles dislodged therefrom. The inlet duct includes a gas distribution baffle having a rigid pervious upper portion and flexible substantially impervious lower portion, preferably a chain curtain, to permit particle accumulations in the inlet duct to pass into the shell for collection in the hoppers.

Abstract: An electrostatic precipitator for cleaning a gas flowing therethrough comprising a shell having a gas inlet and outlet port and defining a gas chamber therein. Sets of spaced collector electrodes are suspended within the shell, the collector electrodes defining gas passages therebetween. Discharge electrodes are suspended within the gas passages for ionizing particles in the gas for collection by the collector electrodes. Hoppers are suspended below the collector electrodes for collecting the particles dislodged from the collector electrodes, each of the hoppers being suspended beneath at least two of the sets of collector electrodes.
