electrostatic precipitation system of flu gas desulpharisation process with view diagram

Before entering the scrubbing system, the flue gas passes through mechanical collectors and an electrostatic precipitator (Wheelabrator-Frye) for primary particulate removal. The hot flue gas 132 C (270 F) then enters the scrubbing trains through conical wetted—wall quench sections contained in the venturi scrubbers
