The cost-effectiveness of sulfur oxides and particulate matter removal is improved by placing a sulfur oxides or other acidic gases removal system and a multi-stage electrostatic precipitator within a single housing. The sulfur oxides or other acidic gas removal system works by spraying a neutralizing slurry or solution into incoming flue gas to form neutral salts which dry in a reaction zone provided between the sulfur oxides or other acidic gas removal system and the electrostatic filtration module. This system also provides for simple retrofitting of existing systems to include SO2 or other acidic gas removal systems. |
