Flue gas conditioning system
Patent
·
OSTI ID:5748372
This patent describes improvement in a system for conditioning boiler flue gas with sulfur-trioxide for removal of entrained particles with an electrostatic precipitator, including means to provide a controlled flow of sulfur dioxide and air at a temperature only in excess of the condensation temperature of sulfurous acid. The improvement comprises: means to divide the flow of air and sulfur dioxide into a plurality of air-sulfur dioxide flows of reduced volume; a plurality of sulfur dioxide converter assemblies, each sulfur dioxide converter assembly comprising a small heater for the flow of air and sulfur dioxide and a contiguous small catalytic converter, the heater and catalytic converter having a heating capacity and SO{sub 3} conversion capacity sufficient for the reduced volume of one of the plurality of air-sulfur dioxide flows.
