An improved wet electrostatic precipitator for cleaning fuel gas

摘要

An improved wet electrostatic precipitator for cleaning fuel gasThe present technique is a wet electrostatic precipitator (ESP) for removing particulates from a gas to produce a clean gas on a clean gas side of the wet ESP. The gas flows through a duct of the wet ESP in a flow direction substan-tially horizontally from an inlet to an outlet of the wet ESP. The duct comprises an ionization zone for receiving the gas from the inlet, at least one discharge electrode assembly extending into the ionization zone, and a precipitation zone downstream of the ionization zone and fluidly connected to the ionization zone. The precipitation zone includes at least one precipitation electrode assembly. The discharge electrode assembly is suspended from the clean gas side towards the ionization zone such that a discharge electrode of the dis-charge electrode assembly for generating a corona discharge inside the duct is positioned inside the duct.
