ABSTRACT:
Electrostatic precipitators, including wet electrostatic precipitators, having a bank of conductive tubes which receive a gas stream having entrained particulates and an electrode connected to an electric current, wherein the tubes each include an internal restriction creating a hydrostatic pressure more evenly distributing the gas flow between the tubes eliminating the requirement for flow distribution devices, such as air straighteners and perforated plates.
